Abstract
The input impedance of a cylindrical cavity-backed slot antenna has been derived based on the mode matching method and the complex Poynting theorem. Two cavity-backed slot antennas were fabricated to verify the theory. Numerical results agree very well with measurements. It is pointed out that the results should have many applications in conformal antennas and arrays.<>
