Title

Improved Isolation in a Rectangular Microstrip Patch Antenna with defected Ground Plane and Patch using coaxial probe fed for wireless LAN Application

Abstract

A Microstrip Patch Antenna (MPA) with defected ground plane and patch to improve isolation between co-polarization to cross-polarization (XP) radiation is proposed. The proposed MPA consists of two rectangular slots as DGS elements in the ground plane and one circular slot/dot etched near the probe on the patch. Due to these elements, the proposed MPA reduce the cross-polarized (XP) radiation up to 20 dB to provide higher isolation without affecting the dominant mode input impedance and co-polarized radiation pattern of a conventional MPA. The conventional MPA is designed with a centre frequency of 5.2 GHz with a coaxial probe feed using dielectric substrate FR4 epoxy having dielectric constant r = 4.4 and thickness h = 1.6mm. The proposed MPA resonates at 5.04 GHz with a bandwidth of 240 MHz and having S11 of -14 dB. The XP level of proposed MPA is shifting form -20 dB to -40 dB over -650 to 650 by suppressing XP of 20 dB compare to conventional configuration. The proposed MPA achieves an total isolation of almost 45 dB from co-pol peak gain to cross-pol cross-pol radiation.
