This work analyses the performance of different feeding techniques for rectangular microstrip patch antennas used in wireless communications applications, such as in Wimax and LTE technologies. Three types of feeding arrangements are discussed here; Microstrip Line feed, Coaxial probe feed, and Aperture-coupled feed techniques. The performance of microstrip patch antenna system depends on the characteristics of the antenna element and the substrate as well as the feed configuration employed. Here the principal characteristics of interest are the antenna input impedance, mutual coupling, bandwidth, radiation pattern and return loss. In this paper, we analyze these characteristics for each feed technique, and compare them with those of the other techniques. This enables the system designer to make well informed judgement on the best feeding arrangement for his application. MATLAB has been used for the simulations and evaluations of the various performance metrics.
