Novel Shape of UWB Microstrip Patch Antenna with Enhanced Gain Using EBG Structure
A novel shape of microstrip UWB planar monopole with enhanced gain using EBG structure is presented.The structure is composed of a rectangular patch fed by a microstrip line constructed on a 22 × 22mm2,FR4 dielectric substrate.The patch is mitered at the corners of the first radiating slot(45°).Two slots were inserted in the partial ground plane lateral to the microstrip feed line.Mushroom-like circular EBG structures encircle the radiating patch.The operational bandwidth of this antenna extends from 3.5 to 13.5 GHz,with minimum return loss of 50 dB,with average directivity,gain and radiation efficiency of 7.5 dBi,6.5 dBi,82%,respectively.At the upper end of the spectrum,the gain increases to reach 11 dBi.Also due to using EBG structures,the antenna resonates at higher frequency range of 22 to 29 GHz,such that the design applications may be extended to other areas such as vehicular ones.
