U-Slot Patch Antenna Design Using First-Principles Models
There are two principal design methodologies for wideband U-slot patch geometries. The first is based on Coupled Mode Theory and the second is based on Characteristic Mode Analysis. For both, the impedance locus of the resonators is determined by the resonant frequency. In order to generate a good design, it is imperative to use first-principles models. These models can be used to develop a schematic and perform numerical studies. Slot Gbosky
