Abstract
The invention is directed to a cavity backed dipole antenna that has at least a reduced length relative to a reference dipole antenna at the same first frequency of operation and, in some embodiments, an improved bandwidth relative to a reference dipole antenna. In one embodiment, the cavity backed dipole antenna comprises a driven bowtie dipole antenna and a parasitic folded sheet dipole antenna with the driven bowtie dipole antenna located with a boundary defined by the parasitic folded sheet dipole antenna.
