Abstract
A planar microstrip antenna includes one or more aperture-fed circular patch radiating elements capacitively coupled to respective parasitic strip elements. The circular patches are symmetrically disposed above respective ground plane apertures, and the parasitic strip elements are annular sectors that are co-planar and concentric with the circular patches, and placed adjacent to the periphery of each circular patch. The disclosed geometry enhances the input impedance bandwidth, and significantly reduces off-boresight radiation variability to provide beam directivity that is more uniform over both frequency and direction.
