Abstract: | The electromagnetic field integral equation in the quasi-optical cavity is obtained using the dyadic Green's function. An
expression is derived for the input impedance of a single microstrip patch cavity excited by a coaxial probe using moment
method. The input impedance of a rectangular microstrip patch is discussed with this method. The result of this paper is similar
to that of the microstrip antenna. This paper is of very important value for designing microstrip quasi-optical oscillator.
