Introduction of a Novel Technique for the Reduction of Cross Polarization of Rectangular Microstrip Patch Antenna with Elliptical DGS

This paper describes a new technique in reducing the cross-polarization (XP) radiation in a rectangular microstrip patch antenna with elliptical defected ground structure (DGS). The use of DGS on the ground plane of the substrate is easy and can simply be applied in many microwave designs. This proposed structure only reduces cross polarization without affecting the characteristic impedance and co-polarization pattern compared to a conventional standard microstrip patch antenna. Simulation results for return loss, co-polarization and cross-polarization (XP) of the designed rectangular microstrip patch antenna with elliptical DGS are presented.
