Abstract :
A simple formula for the input impedance of rectangular patches is derived using the cavity model and the mode matching technique. It is shown that the input resistance, Rin, can be written in a closed form at ´resonant frequency´ defined for the dominant TEM mode. The reactance, Xin, requires a large number of higher mode coefficients.
