A New Method for Analyzing Large Size Parabolic Cylindrical Reflector Antenna

This paper proposes a new method for analyzing the reflector antenna by incorporating the simulating results from EM software into the theoretical computation, and the coupling effect between the horns can be considered by this method. To show the accuracy and validity of the proposed method, a parabolic cylindrical reflector antenna with a horn array feed is investigated. Compared with entire simulation by EM software, this method can save the computation time and improve the computational efficiency. It is very proper to analyze the large size reflector antenna
