一种改进的对拓Vivaldi天线设计
Design and improvement of an antipodal Vivaldi antenna
摘要
Abstract
In this paper,a novel antipodal Vivaldi antenna (AVA) is presented.The radiation flares were modified by a new composite compound exponential curve.A novel director containing two hybrid elliptical metal patches was adopted to improve the radiation parameters (gain,beam tilts and cross-polarization).The measurement results show that the proposed antenna operates from 1 GHz to more than 40 GHz with peak gain > 0 dBi in the range of 1 ~40 GHz and >12 dBi over the 15 ~40 GHz range.The squinted beam of E-plane is less than 3° from 3 to 40 GHz and less than 2° from 20 to 40 GHz.关键词
