This talk presents recent trends and challenges in the development of base station antennas for the 5G wireless systems with high spectrum efficiency, deployment efficiency, and energy efficiency. To improve the spectrum efficiency, upgrading xTxR is applied for sub 1GHz and massive MIMO is adopted for upper 1 GHz. For achieving fast 5G site deployment, we propose the concept of “Active + Passive” antenna modernization to use one passive antenna to incorporate 2/3/4G frequency bands and one active antenna to deploy 5G, such as C-band massive MIMO. The signal direct injection feeding (SDIF) and laser welding technologies are introduced in base station antennas for high energy efficiency. The challenges and solutions for developing the aforementioned high-efficiency base station antennas will be discussed.
Weihong Xiao received the Bachelor and Master degrees from the University of Electronic Science and Technology of China (UESTC), Chengdu, China, both in Electronic Engineering, in 2003 and 2006 respectively.
Mr. Xiao has been with Huawei Technologies since 2006, where he is the CTO for Base Station Antenna. Under his leading of the antenna R&D, Huawei has become the Market Leader in base station antenna. The newly launched Huawei Blade AAU Pro has been widely recognized in the industry, packaging the iF Design Award, Red Dot Design Award, and Best Mobile Network Infrastructure Award. His research interests include the theory and design of antennas and arrays for base station, and the integration of antenna, filter and wireless algorithm for 5G mobile communications. He holds over 130 granted and pending US/WO/PCT/CN patents.
