Summary:
A Planar Inverted-F Antenna (PIFA) with novel compact double-layer Electromagnetic Band-Gap (EBG) structure is presented. The upper layer of the EBG structure is formed by an interdigital structure and a cross-slot is embedded in a metal patch as the lower layer. Compared with a conventional PIFA, the simulated -10dB impedance bandwidth of the proposed PIFA is broadened by 48% with similar directivity pattern characteristics. In order to verify the simulated analysis, antenna prototypes are fabricated. From the measured results, the bandwidth has been improved from 550MHz to 800MHz, which means an expansion of 45%. The measured results basically show agreement with the simulated results, which illustrates the superiority of this PIFA with the EBG ground plane.
