Abstract

In this paper, the miniaturization of linear polarization microstrip patch antenna is studied by attached Irises near the square linear polarization microstrip patch antenna which are induced the increase of current path. Microstrip patch antenna having the Irises is designed and fabricated at the resonant frequency of 1.575 GHz. The result is like that the resonant length of patch is reduced 41.5 mm which correspond to 50.9 % of that of plane type(81.5mm). The return loss is -28.5 dBd and -10 dB bandwidth is 103 MHz( 6.5 %). And as the radiation pattern is broad through the size reduction of patch, the gain is 5.9 dBd and -3 dB beamwidth of E-plane is $111.9^{\circ}$.
