AbstractThe input impedance of a probe-fed, annular-ring-loaded, circular-disk microstrip antenna is analyzed using three methods of increasing complexity. The first method uses a new variational formula. The second method uses a mode-matching method. The third method uses the mode-matching method with a diaphragm at the coaxial aperture. The mode-matching methods are identical to the variational formula under the single-mode approximation. When a diaphragm is present, the single mode approximation is insufficient, implying the variational formula is inaccurate when a diaphragm exists.
