20150070229 | ANTENNA ARRAY STRUCTURE WITH DIFFERING ANTENNAS - An antenna array structure includes a plurality of antennas, wherein a first antenna has a first geometric shape, provides a first radiation pattern, and has a first frequency bandwidth. A second antenna has a second geometric shape to provide a second radiation pattern and has a second frequency bandwidth. The first and second frequency bandwidths at least partially overlap to include channels of interest. An antenna processing circuit sends one or more transmit signals to one or more of the antennas for transmission via one or more of the channels of interest and receives one or more receive signals from the one or more of the antennas or from another one or more of the antennas via the one or more of the channels of interest or from another one or more of the channels of interest. | 03-12-2015 |
20150085710 | WIRELESS TRANSCEIVER WITH CIRCULATOR-BASED QUADRATURE DUPLEXER AND METHODS FOR USE THEREWITH - A wireless transceiver includes a transmit path configured to generate a radio frequency (RF) transmit signal for transmission via an antenna. A receive path is configured to receive an RF receive signal via the antenna. A circulator-based quadrature duplexer includes an in-phase circulator and a quadrature-phase circulator configured to couple the transmit signal from the transmit path to the antenna while generating a residual transmit signal on the receive path, and to couple the receive signal from the antenna to the receive path. The circulator-based quadrature duplexer promotes cancellation of the residual transmit signal on the receive path. | 03-26-2015 |
