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.
In the first part the fundamental parameters of a base station antenna are discussed in the context of radio network design. In particular we discuss parameters such as gain, radiation patterns, frequency bands and beam forming and put them in the context of cell planning, propagation and capacity.
Thereafter, we give an overview of the underlying theory of diversity, MIMO and massive MIMO antenna systems. In particular we look in detail at the implementation of multiple antenna systems and the various transmission modes into the 3GPP standard.
In the following parts we discuss the design of advanced antenna systems (AAS) for low-, mid- and millimeter wave bands as well as antenna designs for Fixed Wireless Access (FWA)
We then continue to discuss the design of antennas for Wi-Fi, small cells and mesh networks.
The final part of the course deals lens antennas of various kinds (both Luneburger and Butler type), their design and application in both cellular and Wi-Fi networks
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 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.
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”.
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.
