微带馈电的双陷波超宽带天线

一种微带馈电的双陷波超宽带天线

内容简介：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。

Abstract：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 characteristics and antenna pattern using simulation software HFSS.The results show that in the frequency range of 3.0 GHz to 12.5 GHz,the proposed antenna can provide an ultra wide voltage standing wave ratio（VSWR2） and two notched bands of 3.25~4.10 GHz and 5.3~5.86 GHz,which can be used for ultra-wideband communication system.
