  • Planar wideband antennas
    Patent number: 7027002
    Abstract: Wideband antennas with omnidirectional coverage have both military and commercial applications. In one embodiment, the Planar Inverted Cone Antenna (PICA) is composed of a single flat element vertically mounted above a ground plane. A geometry of Planar Inverted Cone Antenna (PICA) is based on the conventional circular-disc antenna with trimmed top part having the shape of a planar-inverted cone. in a second embodiment, the Fourpoint antenna also provides balanced impedance over the operating band and has useful radiation patterns and dual polarization over its operating frequency.
    Type: Grant
