Abstract: In this paper a microstrip patch antenna with defected ground structure is proposed for X-band applications. The antenna is compact with size profile of 20 x 25 x 1.6 mm3 and the used substrate for designing the present antenna is FR-4 epoxy. The substrate has relative permeability of 1 and relative permittivity of 4.4 with a loss tangent of 0.02. The impedance bandwidth of the proposed antenna is 0.38 GHz (8.06 GHz – 8.44 GHz) with resonates at 8.22 GHz and 0.54 GHz (9.79 GHz – 10.33 GHz) with resonates at 10.06 GHz. The excitation supplied through a 50ohm microstrip feed line. The performance of the present antenna has been simulated and analyzed with the High Frequency Structure Simulator (Ansys HFSS v15.0).
