| 摘 要： | 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. |
