摘要：
The analysis and calculation of patterns of Cassegrain antennas are presented in detail. Usually in the calculation it is unavoidable to compute the integrals across the main reflector of the antenna. Thus for a large reflector the computation time is very long. Here this question is studied systematically. By means of a series of mathematical evaluations the integration across the main reflector of the antenna is transferred to the aperture of the feeder and therefore the computation labour is drastically reduced. Moreover, a series is given of simplified formulas of patterns suitable for numerical calculation by ordinary microcomputers. © 1990 IEEE
