Abstract
A cavity-backed rectangular 4-slot array can be used to emulate a monopole where flush mounting is required. The impedance and radiation patterns of this type of antenna are investigated. A mathematical model is developed with sufficient generality to allow analysis of a cavity filled with any homogeneous material. Several specific configurations are analyzed. Calculated results are compared with measured data
