In this thesis, the compact microstrip patch antennas in stackedrnconfiguration have been proposed. The microstrip patch antenna structurernconsists of a square patch with four equal u-shape on four sides of eachrnpatches. These structures provide an optimized patch area resulting in arnsubstantial reduction in size compared to a typical microstrip square patchrndesigned at the same frequency of operation. The characteristics of thernantenna are obtained in terms of return loss, gain, radiation pattern andrnbandwidth and are compared with the conventional microstrip patch. Thernstacked configuration enhances both gain and bandwidth of the microstriprnpatch antenna at 2.45GHZ operating frequency. A size reduction of 70% isrnobtained along width 24.4dB gain and 6.6519GHZ bandwidth. The empirernsoftware is used to obtain the optimized performance of the proposedrnantenna. This antenna is found to be suitable for WLAN communications.rnKey Words: size reduction, stacked microstrip patch antenna, gain,rnbandwidth.
