| 20080211727 | SYSTEM AND APPARATUS FOR TRANSMITTING A SURFACE WAVE OVER A SINGLE CONDUCTOR - A low attenuation surface wave transmission line system for launching surface waves on a bare and unconditioned conductor, such as are found in abundance in the power transmission lines of the existing power grids. The conductors within the power grid typically lack dielectric and special conditioning. Accordingly, the present invention includes a first launcher, preferably including a mode converter and an adapter, for receiving an incident wave of electromagnetic energy and propagating a surface wave longitudinally on the power lines. The system includes at least one other launcher, and more likely a number of other launchers, spaced apart from one another along the constellation of transmission lines. The system and associated electric fields along any given conductor are radially and longitudinally symmetrical. | 09-04-2008 |

| 20120188137 | BROADBAND ANTENNA SYSTEM ALLOWING MULTIPLE STACKED COLLINEAR DEVICES AND HAVING AN INTEGRATED, CO-PLANAR BALUN - A broadband antenna system is disclosed. The antenna system relates to a cylindrical structure, wherein the feed region comprises segmented radiators with tapered feed points, distributed around the circumference of the structure, and a balun that is co-planar with the cylindrical structure. This allows a plurality of feed lines, cables, piping, or other structures to be run through the center of the antenna without interfering with the performance of the antenna system. Segmentation of the radiators permits the integration of a corporate feed network, suppresses overmoding and permits operation without the need for a ground plane. The invention further relates to a stacked broadband antenna system wherein additional antenna elements or devices may be stacked collinearly on the antenna structure and operated via the plurality of feed lines or other structures. The overall system thus provides a wide range of transmitting, receiving, sensing and other capabilities over a virtually infinite bandwidth. | 07-26-2012 |

| 20140327590 | Method For Direct Connection Of MMIC Amplifiers To Balanced Antenna Aperture - A MMIC amplifier is directly connected to the balanced feed points at the aperture of an antenna to eliminate the distance between electronics coupled to the antenna and the antenna itself, such that interfaces, components and connection lines which introduce losses and parasitic effects that degrade system performance are eliminated due the direct connection. Expanding the aperture of the antenna to accommodate the direct connection of a MMIC amplifier to balanced feed points of an antenna has been found to have no deleterious effects on antenna performance. Moreover, when coupling the MMIC amplifier to an unbalanced coaxial line, any associated ripple is minimized due to the direct connection. | 11-06-2014 |
