20150155609 | FEEDING NETWORK FOR BASE STATION ANTENNA - The present disclosure relates to feeding networks for base station antenna. Embodiments of the disclosure may comprise first and second phase shifters, and a 3-way power divider, including an input terminal, a first output terminal for feeding a first unit, a second output terminal connecting to the first phase shifter, and a third output terminal connecting to the second phase shifter. The feeding network may also comprise a first 2-way power divider, including an input terminal connecting to the first phase shifter, a first output terminal for feeding a second unit, and a second output terminal for cascading a third phase shifter. In addition, the feeding network may comprise a second 2-way power divider, including an input terminal connecting to the second phase shifter, a first output terminal for feeding a third unit, and a second output terminal for cascading a fourth phase shifter. | 06-04-2015 |
20140354492 | MICROWAVE ANTENNAS FOR EXTREMELY LOW INTERFERENCE COMMUNICATIONS SYSTEMS - Microwave antennas having optimized performance are provided. The microwave antennas include a primary reflector having effective foci arranged in a generally circular or elliptic range around a central axis thereof, and a matching component filling a hole at a bottom center portion thereof. The structural parameters of the microwave antenna are tuned by an aperture field analysis method to optimize the overall performance. | 12-04-2014 |
20130265204 | COMPACT FOUR-WAY TRANSDUCER FOR DUAL POLARIZATION COMMUNICATIONS SYSTEMS - A compact four-way transducer (FWT) is provided for a microwave communications system. The compact FWT is a compact assembly that is configured to process microwave signals in dual-polarization antenna feeds and to provide single polarized signals for four communications channels. The compact FWT includes four terminals facing different directions at one end for receiving/sending single polarized signals, and a terminal at an opposite end for receiving/sending dual polarized signals. | 10-10-2013 |
20130187822 | WIDEBAND DUAL-POLARIZED RADIATION ELEMENT AND ANTENNA OF SAME - A wideband dual-polarized radiation element includes two pairs of cross polarized dipoles and baluns which correspondingly feed current to each dipole in a balanced manner. Each dipole includes a pair of unit arms aligned on a top end of the corresponding balun. One end of each unit arm is connected on top of the balun, and the other end of one unit arm is bending inwards to form inward loaded line, and the other unit arm is bending downwards to form downward loaded line. An antenna includes a metal reflector and at least one wideband dual polarized radiation element, which has excellent radiation and polarization performance. | 07-25-2013 |
20130155588 | Phase Shifting Device - A phase shifting device, including: a housing; and at least one multipath phase shifter assembly in the housing, wherein the multipath phase shifter assembly includes at least two phase shifters disposed in parallel in a planar arrangement. | 06-20-2013 |
