In this paper, a rectangular patch antenna is miniaturized by changing tile middle of patch into narrow microstrip line except the edges of the patch where the fringing field occurs. Miniaturizing rate, gain, radiation patterns of suggested antennas were compared with general square microstrip antenna by using simulator Ensemble. As a result, it reduces the size of antenna by 30% and improves the characteristic of X pol as a advantage while it reduces gain and bandwidth.
