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: A multi-band single feed dielectric resonator antenna (DRA) and DRA array are provided. The DRA is made of a dielectric material having a first and second antenna regions wherein the second antenna region has a different dielectric constant than the first antenna region. The dielectric material is supported by a feeding substrate. The feeding substrate has a top surface ground plane having a slot positioned below the first antenna region of the dielectric material and a microstrip feeding line on the bottom surface in alignment with the slot on the top surface ground plane.

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.
