基于MEMS开关的方向图可重构天线的设计
Design of pattern reconfigurable antenna based on MEMS switch
摘要
Abstract
This paper presents a broadband and wide-angle pattern reconfigurable antenna. The antenna is composed of four different linear arrays, in which the element is designed with different phase shift. The pattern of the whole antenna can be changed by the RF-MEMS switch, which is planed in the feed network. The feed network uses a novel compact broadband impedance transformer, and the microstrip slot antenna acts as an antenna element. The VSWR of the antenna element in a broadband from 2.4 GHz to 3.4 GHz is less than 2. The simulation result demonstrates that the reconfigurable antenna realizes different patterns(0°,25o,40°and 50°) in different RF-MEMS switching states, furthermore, the VSWR of the reconfigurable antenna under each of these four different states is less than 2 from 2.5 GHz to 3.25 GHz except for part frequency points.关键词
