摘要： The disclosed structures and methods are directed to antenna systems configured to transmit and receive a wireless signal in and from different directions. A switchable lens antenna has excitation ports radiating radio-frequency (RF) wave into a parallel-plate waveguide structure, and a frequency selective structure (FSS). The antenna presented herein is configured to operate in two modes depending on a steering angle of the RF wave propagating in the parallel-plate waveguide structure. When the steering angle is about or less than a threshold steering angle, FSS is OFF due to its stubs being electrically disconnected from the parallel-plate waveguide structure. When the steering angle is higher than the threshold, FSS is ON with stubs being electrically connected to the parallel-plate waveguide structure. When ON, FSS provides phase variance to the RF wave propagating in the parallel-plate waveguide structure and increases steering angle of the RF wave.

摘要： A Printed Circuit Board (PCB) comprising various integral components and method of manufacture are provided. The PCB includes a Substrate Integrated Waveguide (SIW), integrated waveguide antennas disposed above the SIW, apertures formed in SIW for coupling with the waveguide antennas, a transmission line routed above the SIW and using the SIW as a ground plane thereof, and further antennas, integrated into the PCB and disposed above and coupled to the transmission line. The SIW and the transmission line may be branched structures for feeding corresponding arrays of waveguide antennas and further antennas. Coplanar waveguides may also be integrated into the PCB and coupled to the SIW and the transmission line via integral impedance matching structures. PCB feature re-use and component interleaving may provide for a desirable and manufacturable PCB structure.

摘要： A variable capacitance and control system used in a compensative manner to improve efficiency in power amplifier arrangements arranged to receive a power input which is voltage-modulated responsive to at least one control signal representative of the data signal. Also included are methods and software for controlling said power amplifier arrangements including the variable capacitance and control system. The data input to the power amplifier is pre-distorted and the resulting power amplification is substantially linear. The arrangement may be used in wireless base station transmitters, for example. Improved data transmission services are also provided which make use of such power amplifiers.
