Patch Antenna Cavity Model Overview
Patch Antenna Cavity Model was introduced in 1978
Models the patch antenna as a lossy resonant cavity.
Details are presented in this video.

Advantages:
Applicable to rectangular, circular, ellipse and triangular patch shapes.
Accounts for higher order modes.
Accounts for the feed inductance.
Provides physical insight into antenna operation (resonant modes).
Drawbacks:
Unable to analyze multilayer patch antenna elements.
