A systematic method to design single-patch broadband microstrip patch antennas

A simple electrical network for a single-layer microstrip patch antenna (SLMPA) and the feeding structure (coaxial probe and compensating capacitor) is proposed to predict the input impedance. The mathematical analysis allows us to design an optimum feed that enhances the impedance bandwidth (BW). © 2001 John Wiley & Sons, Inc. Microwave Opt Technol Lett 31: 185–188, 2001.
