Abstract :
In this paper, a physically-based numerical model is proposed to analyze single/double line-fed patch antennas and circuits based on the method of moments (MOM), where the number of unknowns can be significantly reduced using simplified meshes. In the proposed model, two kinds of new basis functions are used to describe the currents on the feedlines and the feedline-patch junctions. The accuracy and efficiency of the improved MOM model are illustrated by numerical results.
