Abstract

Based on the microstrip antenna transmission-line model, patch-to-patch mutual coupling and slot-to-microstrip coupling model, a novel model method to analyze aperture-coupled rectangular microstrip antennas with parasitic elements has been presented. MATLAB codes have been developed to analyze the input impedance and the far-field radiation patterns of patches with and without parasitic elements. After that, some interesting phenomena have been observed. Comparison between the derived results and experimental results has shown the efficiency and accuracy of this method.
