Analysis of Curved Frequency Selective Reflector Antenna Systems – a Combined Approach

This paper presents a combined analysis approach suitable for analyzing complex reflector antenna systems comprised of both simple PEC reflectors and frequency selective surfaces. The approach joins several methods and models, including Complex Conical Beams, Physical Optics, Spectral-Domain method and the Uniform Theory of Diffraction. The method is tested on a frequency-selective dualreflector system of the Gregorian type, designed for the operating frequency of 25 GHz.
