摘要
根据微波暗室中天线近场测量系统的需要,设计了一副频率范围为0.5~4.5GHz的Vivaldi宽频带微带天线,并利用高频结构仿真软件HFSS对所设计天线的几何结构进行了优化,计算了天线的驻波比、方向图等重要的电性能参数。仿真结果表明该天线在整个工作频段内的电磁特性能很好地满足宽频带天线的技术指标要求,加工成型后可用在宽频带测量系统中作为标准的接收天线。
According to the requirement of near field measurement system in anechoic chamber,a Vivaldi wideband microstrip antenna in 0. 5~4.5 GHz is designed. By using high frequency structure simulation software HFSS,its structure is optimized and VSWR and radiation pattern are computed. The results show that electricmagnectic performance in whole band satisfies with the need of wideband. Furthermore,it can be a standard receiving antenna in wideband measurement system after processed.
