Large Bandwidth Antenna for Electronic Attack

An new compact multi-polarization antenna element design, array and associated feeding arrangement is proposed that enables large multiband coverage to meet the need for a rugged, light weight solution to the electronic attack antenna requirment. The proposed solution meets essentially all of the solicitation's requirements with a retrofittable, cost effective and emminantly produceable design. The new element is electrically small and virtually 100% efficient, without the use of any temination. The array permits steering of the beam in the elevation plane, and a novel feeding approach permits vernier pointing adjustments in both the azimuth and elevation planes.BENEFITS: The proposed designs offer several potential benefits in commercial appications. The proposed element is smaller than corresponding antenna elements covering the same bands, efficiency and polarization regimes. This would enable smaller antennas for devices needing diverse frequency antennas such as cellular phones that might cover GPS and a diversity of network frequencies (PCS, GSM, etc.). Transmit and relay towers needing to service wide bandwidth markets might also find utility in the proposed designs, permitting the potential elimination of multiple antennas and arrays.
