A Simple Radiation Model for Micristrip Antennas

An approach that uses a combined theoretical and experimental best-fit technique for developing radiation models for patch type microstrip antennas is proposed. Far-field expressions involving two major parameters relating the equivalent electric and magnetic type sources in the model are derived. The appropriate values of these parameters are obtained by comparing the computed patterns with the measured ones. Using the proposed model, some antenna characteristics may be more accurately determined compared to the results of some previous studies.
