Analysis of Offset Dual Reflector Antennas Using the Zernike Polynomials

Zernike 다항식을 이용한 오프셋 복 반사경 안테나의 해석

Fast analysis method for calculating the radiation pattern of offset dual reflector antenna are presented. The validity of proposed method was verified by comparing with results of PO/PO, GO/PO, and the equivalent paraboloid method. Proposed method is the series expansion method using the Zernike polynomials. The calculated results by using the Zernike polynomials are in good agreement with obtained results by GO/PO and equivalent paraboloid method except PO/PO.
