| description | An antenna comprising a ground plane, a composite radiation patch, and an excitation circuit is described herein. The composite radiation patch is disposed on a printed circuit board and comprises a conducting plate and a plurality of conductive strips. The composite radiation patch comprises an outer region and an inner region separated by a circle of a given radius. The conducting plate comprises 1) a first set of arcuate slots disposed on the circle and 2) a second set of slots each contacting an external perimeter of the conducting plate at one end and a corresponding slot of the first set of arcuate slots at another end. The plurality of conductive strips is disposed within the outer region of the composite radiation patch, with one or more of the plurality of conductive strips galvanically contacting the conducting plate. The excitation circuit is disposed on the printed circuit board for exciting a right hand circularly polarized wave. The excitation circuit comprises a plurality of microstrip lines and a feeding network to which the plurality of microstrip lines are connected. |
