Abstract
A patch-type antenna is disclosed for radiating electromagnetic radiation in the microwave band. The antenna comprises first and second electrically conductive plates which are supported in spaced-apart parallel relationship. The first plate serves as a ground plane, whereas the second plate forms a patch antenna element. A feed element supplies RF energy to the patch antenna without physically contacting it. This feed element is formed by an elongate, electrically conductive strip line arranged between the two plates and extending from one edge of the second plate to an interior point thereof. The length of this feed element, in its longitudinal direction, is approximately equal to one fourth of the wavelength of the EMR radiation by the antenna at the radio frequency applied thereto.
