Abstract

In this paper the analyses for the input impedance of the probe-fed microstrip disk antenna with a diaphragm at the coaxial aperture have been made by means of mode matching theory and integral equation method. The theoretical results are in excellent agreement with experimental data. It is shown that the change of the gap capacitance will affect the resonance frequency and the input resistance at the resonance significantly when the dielectric substrate is electrically thick.
