Abstract :
The wall admittance of a circular patch on an electrically thick substrate is formulated. Both the electric and magnetic surface currents are considered to be the sources of outside radiation. For the external field, the analysis is carried out in the Hankel transformed domain. Numerical results for the resonant frequency and the input resistance at resonance are shown.<>
