Abstract :
A Novel EBG grounded PIFA has been designed for Universal Mobile Telecommunication System (UMTS) frequency band (2.1 GHz) with good directivity. In this paper a uniplanar compact Electromagnetic Band Gap (UC-EBG) structure is designed to use as ground for a Planar Inverted F Antenna (PIFA), to improve its radiation pattern and suppress the surface waves. The proposed EBG grounded PIFA has shown improvement over conventional PIFA in directivity, front to back ratio and radiation pattern. The front to back ratio has been improved from 8.75 dB to 15.80 dB.
