带引向器的非对称平衡对拓Vivaldi天线设计
Design of an Asymmetric Balanced Antipodal Vivaldi Antenna with a Director
摘要
Abstract
A modified asymmetric balanced antipodal Vivaldi antenna is designed.The outer edges of the radiation patches are modified by a 3-order polynomial curve to achieve an extremely large impedance bandwidth.A metal patch is inserted in the antenna aperture to enhance the radiation characteristics.The beam tilts in E-plane are further compensated by introducing structure asymmetry on radiation patches.The measured results show that the proposed antenna achieves a very wide bandwidth from 2 to more than 40 GHz with peak gain ＞0 dBi and ＞14 dBi over the 15 ～ 30 GHz frequency range.Moreover,the squinted beam of E-plane is less than 3° from 6 to 40 GHz.The proposed antenna has advantages of simple structure,compact size(44 mm×98 mm),and stable radiation patterns.This antenna can be a good candidate for phased array,ultra-wideband(UWB) system and so on.关键词
