In this paper, the authors describe variety of feeding techniques applicable for rectangular microstrip antenna for 2.4GHz ISM applications. Mirostrip lines are excited for radiation modes using different techniques which lead to best impedance matching between the feed line and the patch. A proper impedance matching condition between the line and patch without any additional matching elements are used. After describing various feeding techniques, the paper gives a better understanding of the design parameters of an antenna and their effects on bandwidth, return loss, efficiency and directivity.
