چکیده
A simple and ridged circular patch antenna element excited by a transmission line proximity method is analyzed. The approach is based on conserving the power action at the ridged position using the cavity model with the assumption of a linear variation of the current distribution on the overlap portion of the line and the patch. The smallest line to ground plane spacing for which a match of the radiator to the line is feasible is found for a given thickness and the patch radius.
