Design and Simulation of Dual Band Planar Inverted F Antenna (PIFA) For Mobile Handset Applications

Praveen Kumar, B Amulya

Abstract


In this paper, dual band Planar Inverted F Antenna (PIFA) is presented for mobile handset applications at dual frequencies. PIFA is a flat structure, simple and easy to fabricate. The idea of U-shaped slot technique is introduced into the basic rectangular patch antenna for higher GSM frequency. The impedance bandwidth covers GSM 900 and GSM 1900 bands. The PIFA covers a bandwidth of 31.9MHz (0.88-0.911GHz) or about 3.5% with respect to the resonance frequency at 0.89GHz. For the higher resonant mode the impedance bandwidth is 112.7MHz (1.873-1.985GHz) or about 5.83% with respect to resonance frequency of 1.93 GHz. The PIFA has a gain of 2.59dB and 5.12dB at lower and higher resonating frequencies respectively. PIFA is analyzed using High Frequency Structure Simulator (HFSS).

Keywords: Planar Inverted F antenna, Return loss, GSM 900, GSM 1900
