摘    要:结合倒F天线和可重构天线的优点设计一个用于中国移动多媒体广播的频率可重构的倒F天线。天线使用微波PIN二极管和变容二极管来实现频率可重构功能。测试结果说明本文设计的天线在450-800MHZ频率范围内,反射系数<-10dB的工作频率是连续可调的,结果同时说明在整个频率范围内不同工作频率下辐射方向图近似全向辐射且方向图比较稳定。

关 键 词:倒F天线  频率可重构天线  地面广播  中国移动多媒体广播  CMMB

Abstract:A frequency-reconfigurable printed inverted-F antenna for terrestrial broadcast application is presented.PIN diodes and variable capacitor diodes are used in this antenna to reconfigure the operating frequency.In order to expand its operating frequency bandwidth,two inverted-F structures are integrated in a printed circuit board.Simulation and measured results show the operating frequencies are varied with the junction capacitance or the reversed-bias voltage of varicaps.The far field radiation patterns ill...
Keywords:inverted-f antenna  reconfigurable antenna  terrestrial broadcast  CMMB
