Analysis of P-Band Parabolic Cylinderical Reflector Antenna Using Method of Moments
P 波段抛物柱面天线的矩量法分析

A numerical simulation is conducted to analyze a parabolic cylinderical reflector antenna with 7-half-wave-dipole array as feeder using the method of moments(MoM).The influence of offsetting the feeding array from the focal line is numerically studied.Results show that minus or plus offetting of feeder along the radial direction induce different effects both on the pattern and on the input impedance.Results also show that different diameter of dipoles impact much more on the input impedance than on the radiation pattern.Beam steering is also simulated.
