Measurement and Analysis of the Lowest Resonant Mode of a Spherical Annular-Sector Patch Antenna

Abstract

The cavity model for patch antennas has been used extensively since the 1970s. This model gives excellent first order estimates for the antenna's internal fields near any resonant frequency. While frequently used for planar geometries, there is no reason why the model cannot be employed for other geometries. This paper discusses some of the complexities in selecting the correct pair of linearly independent associated Legendre functions when attempting to employ the cavity model using a spherical geometry.
