Abstract

A numerical technique previously developed by the authors (IEEE Trans. Antennas and Propagation, vol.AP-34, p.1080-1091 (1986)) is extended to various microstrip antennas fed by a probe through a ground plane. The modeling technique adopted a dynamic Green´s function formulation. The substrate thickness considered here is arbitrary. The rigorous analysis is based on a reaction integral equation derived from the reciprocity theorem. The method of moments is applied to solve for the unknown current distribution in the integral equation. Therefore, this numerical method is particularly suitable for high-frequency applications where the substrate is usually electrically thick.<>
