This short course gives the participants an overview of the application, implementation, and design of base station antennas for 5G, Wi-Fi 6 and beyond.
The course explains underlying theoretical and practical implementation aspects of base station antennas in both cellular communication networks and Wi-Fi, and discusses also their requirements and design.
In particular the course is aimed at microwave-, RF- and antenna engineers working in the wireless area: However, it may also be useful for researchers looking for relevant research topics, and system engineers working on 5G and Wi-Fi 6 needing a deeper understanding of the antenna as a component of their system.
We will give a brief introduction to quantum theory in general, and then introduce the quantization of electromagnetic field, and quantum Maxwell’s equations. We will discuss how dispersion effect can be included into quantum Maxwell’s equations. Then we will talk about quantum numerical mode decomposition, quantum FDTD. We will also discuss how qubits can be modeled, as well as the use of CEM methods in them.
This short course will cover technological areas related to wideband, reconfigurable, beamforming, multifunctional antenna technologies. It is well-known that the forecast wireless communications require the systems to be high-speed, multi-polarization, frequency-reuse, and actively-beamforming for high volume, fast speed and large channel capacity purposes. The system likes 5G starting to launch in the year of 2020 with both microwave and millimeter-wave bands for seamless communications. The frequency spectrum will further extend to terahertz bands for supporting future 6G communications in 2030. However, this goal must be achieved with advanced antenna technologies at such high frequencies. It is therefore, the demonstration of designing high frequency antennas and arrays are very important for the recent wireless communications, in particular to the antenna society. The audience will learn and explore the up-today terahertz and millimeter-wave antennas design through the participation in this proposed short course session.
This short course will cover latest antenna developments for satellite, deep-space and ground applications. It reviews the existing technologies and provides new technologies related to space, deep-space and ground antennas developed over the past 3 years. It includes high frequency antennas, GPS antennas, multi-band antennas and wide-coverage antennas. CubeSats are enabling space-based Earth and planetary science observations, making space science affordable, accessible, and rapidly deployable for institutions such as NASA as well as other space agencies, universities, and private space enterprises around the world. An overview of CubeSat antennas will be provided with a particular emphasize on deployable mesh reflector antennas and reflect-arrays.
Computational electromagnetics (CEM) find extensive applications in antennas, wave propagation, RF/microwave circuits metamaterials and even quantum electrodynamics. In addition, CEM also find usefulness to enhance teaching and learning of electromagnetic (EM) and microwave courses that are often regarded by students as difficult, abstract and complex. This short course will present some contemporary CEM methods with applications to teaching and learning of EM/microwave subjects. Since no students like to wait long for EM simulation demonstrations in class, the CEM methods in this course focus particularly on those that allow `real-time’, ‘fast-forwardable’ computations, covering explicit and implicit finite-difference time-domain (FDTD) methods. Some brief expositions are also given to stable and eigen-free spectral domain analysis of wave propagation in multilayered complex (bi)(an)-isotropic media, as well as frequency domain stability analysis of two-port parameter representations for microwave (circuit, metamaterial, or antenna) networks. The instructor will present several such CEM methods that have been formulated to be well-suited for implementation on mobile devices. Some demonstrations are given for 2D/3D visualizations of wave polarization, reflection-transmission, Smith chart, wave propagation, coupling and resonance on transmission lines, coupled lines, filters, etc. The incorporation of efficient CEM methods onto versatile educational apps on mobile devices could help to enhance instructor teaching and improve student learning, as well as enabling quick initial design and analysis anytime, anywhere.
From frequency selective surfaces (FSS) to electromagnetic band-gap (EBG) ground planes, from impedance boundaries to Huygens metasurfaces, novel electromagnetic surfaces have been emerging in both microwaves and optics. Many intriguing phenomena occur on these surfaces, and novel devices and applications have been proposed accordingly, which have created an exciting paradigm in electromagnetics, the so-called “Surface Electromagnetics”. This short course will review the development of various electromagnetic surfaces, as well as the state-of-the-art concepts and designs. Detailed presentations will be provided on the unique electromagnetic features of EBG ground planes and advanced metasurfaces. Furthermore, a wealth of antenna examples will be presented to illustrate promising applications of the surface electromagnetics in antenna engineering. The course covers representative materials from recent books by the lecturers, “Surface Electromagnetics: With Applications in Antenna, Microwave and Optical Engineering” (Cambridge University Press 2019) and “Electromagnetic Band Gap Structures in Antenna Engineering” (Cambridge University Press, 2009”.
The 5G communication technology will bring new experiences including higher bandwidth, higher data rate or greater capacity, security, and lower latency and will create new opportunities for society.
Mm wave frequency ranged will be adopted in the coming 5G and beyond systems. The realization of these high level technologies brings about new challenges for the antenna and microwave engineers.
In this course, we will the recent progress on 5G mm wave antenna system, antenna design and integration, OTA and EMF, focus on mobile user device application.
In conjunction with the development of conventional natural antennas, the emergence of metamaterials has enabled the development of innovative metamaterial antennas (metaantennas) and broadened the range of antenna applications. These natural and metaantennas can be applied to modern wireless communications between vehicles and base-stations, vehicles and satellites, ships and base-stations, and so forth. This short course presents recent progress in natural and metaantennas, with a focus on beam steering. The course is composed of three chapters.
Chapter 1 starts with the definition of natural and metamaterial antennas, followed by an overview of antenna analysis methods. Some formulations that are useful for antenna design are discussed.
Chapter 2 presents five antennas that radiate a linearly polarized (LP) beam and have beam-steering capability. Firstly, beam steering for three natural antennas (four-leaf, disc-Ts, and BOR-based antennas) is discussed, where LP radiation is generated by a resonant current. Secondly, the discussion focuses on beam steering for two antennas (natural rhombic grid array and bent c-type metaline antennas), where the LP beam is generated by a traveling current i.e., a non-resonant current.
Chapter 3 achieves beam steering for six circularly polarized (CP) antennas: (i) a natural loop grid array; (ii) a metaspiral, a four-metaline, a bent p-type metaline, and a multi-metaloop; and (iii) a patch-metaline. The currents on the antenna conductors in (i) and (ii) flow in a traveling wave fashion. In (iii), standing- and traveling-wave currents flow on the antenna conductors.
Note that the antenna height of the metamaterial antennas presented in this short course is extremely small: on the order of 1/100 wavelength at the operating frequency.
The terminology standards on antennas (IEEE Std. 145) and radio wave propagation (IEEE Std. 211) are important documents that guarantee the right use of accepted terms in technical papers and reports. IEEE Std. 149 (antenna measurement), IEEE Std. 1720 (near field antenna measurement) & IEEE Std. 1502 (radar cross-section measurement) prove useful when performing antenna measurements. The short course will provide an overview of these standards that have been developed by the IEEE Antennas & Propagation Standards Committee.
The course includes printed copies of the antennas & propagation terminology standards:
The short course is limited to a maximum of 15 participants on a first come first serve basis.
The terahertz gap (0.3 – 3 THz) remains still an underused electromagnetic spectral band sandwiched between conventional electronics and optics. It holds promise however for many applications ranging from high-speed wireless indoor communication, high-resolution imaging, security screening and molecular spectroscopy.
For all these applications, THz technology needs to be developed to the standards of microwaves and optics. In this quest, engineers need to be well aware of the current technology and the challenges related to THz in order wangle the next generation of THz components and systems.
This Short Course aims to provide an opportunity for attendees to familiarize with THz technology (CW and pulsed) and dig into the reasons why THz technology lags behind. The storyline of the Short Course will build upon the presenter’s experience with the commercial instruments: (CW) ABmm vector network analyser, Keysight N5247B PNA-X with VDI frequency extenders and TeraSense Tera-1024 imaging system; (pulsed) Teraview Spectra 3000 and Menlo TERA K15 spectrometers, and with an in-house (University College London) near-field time-domain spectroscopy system.
The objective of this course consists in presenting the state of the art and the on-going developments in Multi-Beam Antennas (MBAs) and Beam-Forming Networks (BFNs). They find application in several fields including communications, remote sensing (e.g. radars, radiometers, etc.), electronic surveillance and defense systems, science (e.g. multibeam radio telescopes), RF navigation systems, etc. They may be installed on board satellites, airplanes, trains, buses, buildings, cars etc. MBAs and BFNs are becoming also fundamental elements in emerging MIMO, 5G and 6G communications. The course content is regularly updated by the organizers who are involved since more than twenty years in this domain.
The workshop will present the latest development of AL technology in electromagnetic wave and electromagnetic coupling with neuron-science, such as new electromagnetic challenges in AI chips, Neuromorphic Chips, heterogenous package integration.
The idea of the workshop is to invite worldwide research institutes, Universities, and companies to present their latest work on mmW antenna development. The topics in the workshop are all related to the new antenna development and its applications in MIMO Radar system. The topics may cover following area but not limited by those fields: new antenna proposal and its system implementation, new facilities of simulation tools and measurement tools, MIMO design in mmW Radar system, etc.
