摘要

A model is developed to calculate the input impedance of a coaxially fed circular microstrip disc antenna in L band and C band. A mode matching approach with both electric and magnetic surface current is used, which makes it possible to improve the effects of modes. In addition, the method of images is used to remove the ground plane. Finally comparison is made with CST studio results, as it can be seen the theoretical calculations for input impedance are in good agreement with CST studio results except for minor shift in frequency.
