How is the mathematical modeling of UWB microstrip patch antennas typically approached?

Microstrip patch antennas are traditionally narrowband, yet UWB designs rely on geometric modifications and complex field behavior. I am interested in how researchers mathematically model these antennas, what assumptions are made, and where analytical methods give way to numerical or hybrid approaches.

From my experience working with UWB microstrip antennas, I have seen that purely closed-form models are rarely sufficient across the entire band. Designers usually start with modified transmission-line or cavity models to capture dominant resonances, then extend them using equivalent circuits to represent slots, stubs, or tapered edges. I would recommend treating mathematical modeling as an interpretive tool rather than a predictive one. It helps explain bandwidth generation and impedance behavior, but full-wave simulations and measurements are essential to validate performance, especially when higher-order modes and dispersive substrates dominate UWB operation.
