✦ Synopsis

An analysis of a probe-fed circular patch antenna etched on an electrically thick substrate is conducted. The probe is considered to be the primary source of radiation and the unknown induced current on the patch is determined from the reaction concept. The integral transformation technique is employed in order to obtain various radiation characteristics of the patch. Numerical results reveal that the resonant frequency, input impedance, bandwidth and radiation efficiency vary widely with the thickness of the dielectric substrate. This study may find application in high-frequency printed antennas, especially at the millimeter-wave frequency range.
