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.

Two transmission line structures propagate signals according to two different electromagnetic propagation modes, such as TE, TM, TEM and quasi TEM modes. The two transmission line structures are operatively coupled to different components of the antenna array. One transmission line structure may be a stripline or microstrip, and the other transmission line structure may be a waveguide such as a Substrate Integrated Waveguide. Both transmission line structures may branch to reach multiple elements of the antenna array. The transmission lines may share common features, for example by embedding the stripline within the waveguide.

摘要： 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.

摘要： 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.

摘要： Signals are received from antenna elements in an antenna array, and respective phase shifts are applied to the received signals. The respective phase shifts are relative to a channel phase shift associated with each antenna element, and correspond to side angles from a current antenna beam direction of the antenna array. Control signals based on the phase shifted signals are generated to control the channel phase shifts, to provide beamforming tracking.

摘要： 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.
