Ultra Wideband PIFA Antenna with Supporting GSM and WiMAX for Mobile Phone Applications

In this paper the PIFA antenna with multiband resonance for GSM 900, GSM 1800, WLAN 2400MHz, Bluetooth, WiMAX, 3G, 4G and UWB frequency from 3.1-10.6 GHz application is presented. Slots or stubs on the ground plane produce lower frequency resonance. Taper feed line method has been used to achieve Ultra Wide Band. The final antenna results are compared by FEM and TDM techniques using HFSS and CST microwave studio 2011 simulation softwares. The antenna is built on FR-4 low cost substrate with dielectric constant εr = 4.4 and loss tangent tan δ=0.02. The substrate height is h=1.6 mm and the substrate dimensions are 120mm×60mm. Simulation results of Specific Absorption Rate (SAR) shows that antenna has 1.44 W/Kg and 2.65 W/Kg for GSM 900 and GSM 1800. The antenna has high gain between 2-6.5 dBi with Omni directional radiation pattern. The antenna results are compared with other pervious researches.
