A FURTHER RESEARCH ON THE JACOBI-BESSEL SERIES METHOD IN ANALYSIS OF REFLECTOR ANTENNA
对面天线分析中雅可比-贝塞尔级数方法的进一步研究

Based on the work on reflector antenna with circularly projected aperture accomplished by E. Mittra and others (1979), this paper extends the Jacobi-Bessel series method in analysis of reflector antenna to the area where far-field of paraboloid reflector with elliptically projected aperture can be evaluated by using the unique recurrence relatio ns of modified Jacobi polynomials. Meanwhile, a new kind of partial recurrence relations of the series expasion coefficients pBmn is deduced so that whole CPU time for numerical integration can be saved about three times.
