Enhancement of the Performance Parameters of Microstrip Slotted Patch Antenna using Defected Ground Structure

摘要

This article represents the Microstrip patch antenna with corner slots in the patch and the corner slots in the ground plane. The antenna is developed on Rogers RT Duroid having Dielectric constant 2.2 with height of 1.6 mm fed with coaxial feed at optimized location. The performance parameters of the proposed patch antenna are characterized by measuring Return Loss, Gain, Efficiency, Axial Ratio, Radiation Pattern and Directivity. The presented antenna has low profile and resonates at 12 GHz which can be operated in Xband and KuBand applications like Terrestrial communications and Networking, Motion detectors, Traffic light crossing detectors, Fixed Satellite service and Broadcast satellite service, VSAT etc.
