Study On Antenna Technologies For Modern Wireless Communication Systems

With the high-speed development of modern communication technology, wireless communication technique for excellent performance and high capacity is coming to people's great attention in related fields, of which high altitude platform stations (HAPS) communication and wireless local area networks (WLAN) technique have receiving more and more attention with their unique technical advantages. Antenna is one of the necessary components in wireless communication. Through designing the antenna radiation character effectively, antenna beams'directionality and other character can be controlled, high channel capacity and utilization rate of spectrum can be achieved, resulting in optimizing the performance of the system.Firstly, a brief introduction about the antenna used in HAPS communication system and WLAN is presented in this paper. In the aspect of HAPS, much attention will be paid on the multi-beam antenna used in this...
