Research on the Development of Reconfigurable Antenna in Wireless Communication System

Antenna is the core component of wireless communication system, and its performance has a key impact on the signal quality of wireless communication, communication distance and battlefield situation. Reconfigurable antenna has attracted extensive research and attention due to its excellent characteristics of flexibility, timely switching and stable performance. In view of the practical needs of reconfigurable antenna, this paper first introduces the concept, classification and development trend of reconfigurable antenna, and combs the design methods of reconfigurable antenna and the current difficulties in the design of reconfigurable antenna. This paper focuses on the analysis and summary of the reconfigurable antenna in the amplitude frequency characteristic separation and active switch (varactor) feeding solutions, which provide theoretical guidance and positive suggestions for the reconfigurable antenna design and reconfigurable development direction applied in modern wireless communication system.
