Assessment of the Impedance Bandwith of a Proximity-Coupled Microstrip Patch Antenna

This article proposes a new strategy to design and estimate the impedance bandwidth of a two-layer and single-material PC-MSPA through a math close form. The simulated and experimental results present good agreement with the bandwidth model presented. The proposed analytical enable the evaluation of a proximity-coupled microstrip patch antenna (PC-MSPA) bandwidth that allows developing a framework for more effective designs.
