基于波纹喇叭天线的模式转换器

为提高高功率传输系统的模式转换效率, 利用波纹喇叭的设计方法研究了TE11模至HE11模的转换器。设计了基于正弦－平行剖面以及tanh剖面的2种不同结构的模式转换器, 并利用商业软件进行仿真验证。仿真结果表明, 在94 GHz附近10 GHz的带宽范围内, 高斯度可以达到98.6%以上, 中心频点的高斯度达到99.2%以上。设计的2种结构中, 正弦—平行剖面具有输出束腰半径处于开口处的优点, 而tanh剖面具备尺寸小、相位中心固定的优点。

Abstract

The corrugated horn antenna is investigated for the application of TE11 to HE11 mode converter. Two types of structures, i.e. sin-parallel and tanh profile are designed and verified by using commercial software. It is showed that the Gaussainity is more than 98.6% over a bandwidth of 10 GHz centered at 94 GHz. The Gaussianity can reach 99.2% at the central frequency. It is also seen that the beam waist of the sin-parallel type is located at the aperture of the structure. The tanh type bears advantages of a low-profile and stable phase center.工程项目(2016jxtd055)；安徽新华学院校级重点建设学科项目(zdxk201702)；安徽新华学院校级研究所项目(yjs201706)
