Mutual Coupling Reduction in Patch Antenna Array Using Combination of Shorting Pins and Metallic Walls

Abstract : A method of loaded patch antennas with shorting pins and erected walls in between patch antenna arrays is introduced to reduce surface wave and free space wave coupling in both E and H-plane, respectively. This simple technique works equally well in both orientations by reducing coupling upto -19dB and -15dB (measured value) in E-plane and H-plane, respectively, as compared to conventional patch antenna array. The scattering parameters are studied and conclusions are made on amounts of mutually coupled power and the band width of the rejection band (S12). A parametric study of the variation in level of mutual coupling with respect to height of the wall has been carried out in both E and H-planes. The simulation results are well verified through measurements.
