Abstract
An omnidirectional vertically polarized antenna. A number of antenna elements are each fabricated on a backing, such as a printed circuit board. The front of each antenna element has conductive strips and slots, arranged in an alternating pattern. The back of each antenna element has an antenna feed circuit. An electrically absorptive layer is attached to the back of each antenna element. The antenna elements are assembled together in a nonconductive housing with circumferentially arranged compartments that receive the antenna elements.
