Abstract
In this paper, a single band PIFA antenna designed and simulated in High Frequency Structural Simulator (HFSS) with metamaterial superstrate. The PIFA antenna resonates at a frequency of 2.4 GHz with radiating patch of quarter wavelength (λ/4) parameters consisting of length 26mm and width 30mm placed on top of a ground plane with half wavelength (λ/2) parameters at a height of 10mm. Metamaterial is designed on a substrate of FR4 epoxy having permittivity 4.4 and 0.16mm of thickness with Split Ring Resonator (SRR) structure, placed on top of PIFA separated with a foam material of thickness 1mm. The simulated results are then compared with PIFA without metamaterial and there is a considerable improvement in metamaterial loaded PIFA over the conventional PIFA antenna. Where the return loss is observed at −54.613 dB and a Gain of 5.29 dB. Hence, this antenna serves for practical purpose such as WLAN, Bluetooth, WiMax devices.
