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.

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。
