Publication number: 20070257855Abstract: A horizontally polarized, substantially omnidirectional broadband transmitting antenna uses parasitic dipoles to increase azimuthal circularity over frequency. Because the magnitude of nulls in the field strength increases with frequency, the dipoles are preferentially sized for optimum reradiation at the highest frequency expected for the antenna. For maximum reinforcement of signal strength in the nulls, the longitudinal axes of the dipoles in a preferred embodiment lie in the center planes of the multiple bays of the antenna, are perpendicular to the proximal axes of radiation, and are centered on the nulls. The dipoles are suitable for use with several antenna styles, and are expressly compatible with crossed bowtie slot antennas.Type: ApplicationFiled: May 2, 2006Publication date: November 8, 2007Inventors: Andre Skalina, John Schadler
