Abstract :
A ridged circular patch antenna element excited by a transmission line proximity method is analyzed. The approach is based on conserving the reaction at the ridged position using the cavity model with the assumption of a linear variation of the current distribution on the overlap region of the line and the patch. For a given thickness and patch radius, the smallest line to ground plane spacing for which the radiator is matched to the line is found. Finally, our results are compared with measured data
