Ka-Band Microstrip Patch array Antenna for Satellite Communication

Abstract

Microstrip patch antennas have been modeled and investigated at Ka-Band frequencies, to achieve high gain for satellite communications application. Structures of one, two, three and four elements arrays have been designed, modelled and simulated numerically using MATLAB and CST software at 29 GHz. Different configuration have been tested to find the optimum structure in terms of Gain, input impedance matching, phase matching and spacing between arrays. Various feeding techniques have been tested to find the optimum feed network, which is a combination of series and corporate feed. A gain of 12dB was achieved using the structure of four element arrays with beamwidth of 38 degrees.
