GPS patch antennas are gaining their importance nowadays due to their importance in the communication engineering. This present paper includes the designing of patch antenna for the applications of Global positioning systems antenna in the handheld equipment. The antenna will operate at the desired frequency of 1.57GHz. An RT-Duroid substrate of dielectric constant 2.2 and dielectric loss tangent of 0.009 is used in this present paper. Return loss, input impedance smith chart, 3D gain, radiation patterns and field distributions are simulated and presented in this paper by using commercial Ansoft-HFSS software.
