摘要

波导缝隙阵列仍然是微波和雷达天线最流行的解决方案之一。除了标准的矩形槽外，人们对非矩形槽越来越感兴趣，因为它在某些应用中性能更好。本文给出了一种计算椭圆槽自导纳的完整方法，它比矩形槽具有更好的功率处理能力，并且当偏心距接近1时，交叉极化也很低。利用矩量法在谱域中进行分析，提出了一种计算狭缝(等效)磁电流傅里叶变换的新方法。

Method-of-Moment Analysis of Slender Elliptic Slots

Waveguide slot arrays are still one of the most popular solutions for microwave and radar antennas. In addition to standard rectangular shunt slots, there is an increasing interest in non-rectangular slots, which can perform better is some applications. We present here a complete approach to the computation of the self-admittance of a single elliptic slot, which has a better power handling than rectangular slots and, when the eccentricity is close to one, also a low cross-polarization. The analysis is done in the spectral domain using the Method-of-Moments, and a new approach to the computation of the Fourier transform of the slot (equivalent) magnetic current is presented.
