中文摘要:提出了一种新颖的対拓Vivaldi天线。该天线的辐射耀斑用新的复合指数曲线修正。为改善天线的辐射特性(增益,波束偏离和交叉极化),提出了一个新的引向器,该引向器由两个混合椭圆金属贴片构成。测试结果表明该天线在1到40GHz频率范围内增益>0dBi, 并且在15到40G频段内天线的增益>12dBi。在3到40GHz频率范围内,E面的波束偏离小于3°,并且在15到40GHz不超过2°。

DESIGN AND IMPROVEMENT OF AN ANTIPODAL VIVALDI ANTENNA
Abstract:In this paper, a novel antipodal Vivaldi antenna (AVA) is presented. The radiation flares are modified by a new composite compound exponential curve. A novel director containing two hybrid elliptical metal patches is proposed to improve the radiation parameters (gain, beam tilts and cross-polarization). The Measurement results show that the proposed antenna operates for 1GHz to more than 40GHz with peak gain >0dBi and >12dBi over the 15-40GHz range. The squinted beam of E-plane is less than 3° from 3 to 40GHz and less than 2° from 20 to 40GHz.
