ABSTRACT:
This invention relates to a radiating element, such as a microstrip antenna, having a low input impedance and being capable of allowing high RF power to be supplied to the radiating element. The radiating element incorporates impedance transformation capabilities by providing a dielectric member with an electrically conductive ground plane formed on one side of the dielectric member. A metal patch element is formed on the other side of the dielectric member and spaced from the ground plane by the dielectric member. The patch element is capable of radiating RF energy when coupled to a source of RF input energy applied thereto. An impedance transforming section is selectively located within the perimeter of the patch element to give a desired input impedance at a feedpoint of the impedance transformation section.
