椭圆口径天线的一种新的设计方法

A New Design Method of Elliptic Aperture Antennas

利用口径坐标变换,比较了圆口径和椭圆口径天线方向函数的差异,得出了将圆口径分布方向图特性映射到椭圆口径的条件,并将圆口径天线最佳综合方法圆Taylor综合应用于椭圆口径天线的设计。将这一条件应用于椭圆离散阵设计,给出了设计实例,比较了连续圆口径分布与椭圆离散阵的特性,扩展了椭圆阵列的常规设计方法。

Applying the aperture coordinate transform, this paper compares the difference between circular and elliptic aperture antenna pattern functions, derives the formula of mapping circular aperture antenna pattern properties to elliptic aperture antennas and applies the optimum circular aperture antenna pattern synthesis, Taylor synthesis to elliptic aperture antenna design. And how to use this formula on discrete elliptic aperture arrays is discussed. The paper gives an example of applying this method and compares the pattern properties of continuous circular aperture antennas and discrete elliptic aperture arrays. The method extends the conventional design approaches of elliptic aperture arrays.
