Performance Analysis of a Patch Antenna Array Feed for a Satellite C-Band Dish Antenna

This paper proposes a patch antenna array as an alternative feed for dish antennas on board satellites to solve the weight problem constituted by conventional feed horns. An 8x1 linear, C-Band, circular patch antenna array configuration with a broadside radiation pattern is designed as feed for a dish antenna with F/D ratio of 0.36 corresponding to aperture illumination of 140 degree. The result of analysis and simulations of the model using MATLAB and PCAAD5.0 software suggest that the patch antenna array feed radiation performance is very competitive when compared to that achieved with conventional feeds for dish antennas of the same F/D ratio.
