The dual-polarized patch element is useful in indoor wireless networks for broad bandwidth and modest gains. The focus of this paper is placed on an inset matching network used with a patch element. The purpose of the design is to increase the bandwidth of a microstrip patch by using a thicker substrate with low dielectric constant. However, with such a combination, the input impedance of the antenna becomes inductive. The inductance must be neutralized to obtain a real impedance at the resonant frequency. This is achieved by cutting, on the surface of the patch, a square ring around each connector probe of the patch. This design has a capacitive nature and improves the antenna's response. Experimental results will be presented to demonstrate the performance of the design.
