20120119968 | Radial-free collinear omni-directional antenna with gain and virtual ground - An omni-directional antenna operable absent ground radials and providing at least 3 dB gain at a chosen wavelength relative to a dipole includes first and second like-oriented J-pole antennas and, coupled intermediate said J-pole antennas, a quarter-wavelength non-radiating delay line. Each J-pole antenna includes a half-wave radiating element, and a quarter-wavelength non-radiating section. The quarter-wavelength non-radiating delay line together with the quarter-wavelength non-radiation section of the second J-pole provide a half-wave non-radiating delay line. The result is that RF energy radiated by the first and second half-wave radiating elements are in proper phase, whereby gain is achieved. RF energy is coupled to the first J-pole antenna a distance Δ above the zero impedance end of that antenna. | 05-17-2012 |

20090102737 | J-pole antenna - A J-Pole antenna disclosed including: shunt segment extending out of the plane of the J-Pole antenna. A shunt segment extending out of the plane of the J-pole antenna aids in attaching the antenna to a connector and allowing for a reduction in the size of the antenna and connector. The shunt segment also makes the antenna shorter while preserving the same gain and impedance performance as a conventional J-Pole antenna. A connector plate and connector may be used with the antenna having the shunt segment extending out of the plane of the J-Pole antenna. A protective enclosure may be used with the J-Pole antenna and allowing a radiating antenna segment of the J-Pole antenna to extend from the protective enclosure. | 04-23-2009 |
