一种微带馈电的双陷波超宽带天线

摘要

为适应超宽带通信的需求,设计了一种小型印刷超宽带天线。天线采用五边扇形金属贴片作为辐射贴片,通过开U形缝隙实现阻带特性,利用仿真软件HFSS对天线的阻抗特性及方向图进行研究。结果表明,该天线在3.0~14.0 GHz的频率范围内驻波比〈2,其中在3.25~4.10 GHz和5.3~5.86 GHz两个频率范围内有阻带特性,可用于超宽带通信系统。%In order to meet the needs of ultra-wideband communications,we design a printed UWB Antenna in a small scale.We apply with five-sided metal fan as a radiation patch,adopt the U-shaped slot to achieve stop-band characteristics,and study the impendence char
