Abstract: An antenna for a phased array comprises a plurality of rectangular sub-arrays of individual array elements. The rectangular sub-arrays in the plurality are tiled to reduce periodicity of phase centers of the sub-arrays. The antenna utilizes a phase shifter for each sub-array as opposed to using a phase shifter with each individual array element.

Abstract: A phased array antenna is described that groups radiating elements into rows and columns. The radiating elements in a row are fed by a common phase shifted signal and the radiating elements in a column are fed by a common phase shifted signal. As such, each radiating element is fed by two different phase shifters. The overlapping groupings of rows and columns allows the antenna to be electronically steered by varying the phase shift applied to the rows and columns. The overlapped sub-arrays of the phased array antenna reduces the number of required phase shifters for the antenna array.

Abstract: 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 an initial steering angle of the RF wave propagating in the parallel-plate waveguide structure. When the initial 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 initial 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.

Abstract: A vertical combiner for an overlapping linear phased array is provided. The vertical vector combiner enables two strip-line signals from different layers to be combined, or divided, by vertical transitions between substrate layers and produce a desired output signal phase. The combiner can terminate in a short to act as an antenna. In an antenna application, the antenna provides multiple substrate layers for each strip-line signal, each having a metal ground plane. The ground planes are be coupled by vertical transitions access enabling a stepped ground within the structure which increases bandwidth. The multi-layer combiner architecture enables integration with phased array feed networks for millimeter wave phased array antennas.

Abstract: Systems for a dual-band transceiver that re-uses a lower frequency transmitter to drive a local oscillator (LO) for high frequency circuits are disclosed herein. The need for a LO lineup requiring high frequency and high power is eliminated. The output of a lower frequency band is modified to be used as a LO drive for the higher frequency band transceiver. Using a carrier recovery loop, the system is operable to simultaneously operate in both bands. The result is a solution that eliminate the design of a high performance LO circuits for a higher band of a mmW dual-band system. This significantly reduces the overall complexity of the system. Furthermore, the inventive architecture reduces the design complexity and overall cost to implement dual-band circuit.
