传统的超宽带天线概念是在频域下定义的,有些不能作为时域脉冲天线使用。为实现时域天线的定向性、低剖面、小尺寸、可承受高功率等性能,结合领结天线的低剖面特性和TEM喇叭天线的定向辐射特性设计双极变张角时域天线,该天线是根据光导开关的时域响应设计天线激励源的低剖面定向时域超宽带天线,仿真结果表明,该天线是一种高性能的时域天线。
- Abstract:
- The traditional ultra-wideband antenna is defined in the frequency domain,so some of them can not be used in time-domain pulse antenna.The bipolar variable angle antenna which has performance of directional property,low profile,small size and withstand highpower,combined the advantages of low-profile in bowtie antenna and directional radiation in TEM horn antenna,the novel time-domain antenna is proposed,concerning the photoconductive switch as the generating pulse.This paper gives simulation results of the bipolar variable angle antenna and its main radiation characteristics
