Abstract: The performance analysis of Patch antenna and PIFA (Planar Inverted F Antenna) for operating frequency of 2.4 GHz is presented in this paper. The proposed antenna structure covers WCS (Wireless Communications Service- 2.305-2.32 GHz and 2.345-2.36 GHz) and SDR (Satellite Digital Radio- 2.32-2.325 GHz) bands. The design steps and the detailed dimensions for the antenna structures are discussed. The results for return loss and VSWR are simulated with the help of Ansoft HFSS v13.0. The comparison of Patch antenna and PIFA antenna in terms of return loss is also discussed.
Keywords: HFSS, PIFA, SDR, WCS.
