Abstract: A phased antenna array device comprises at least one input port for interfacing receive and transmit RF signals to/from an antenna array. A feeding line is provided to carry RF signals of two orthogonal polarizations from the input port P1, and at least one antenna feed element with an aperture or cross section having an order of symmetry C4 and supporting RF signals of two orthogonal polarizations is provided. At least one first substrate contains a plurality of antenna elements integrated into the substrate, with each antenna element capable of operating at two orthogonal polarizations. A plurality of phase shifters are connected to corresponding antenna elements, each phase shifter operating at two orthogonal polarizations, the output port of each phase shifter being connected to a short circuit.

Abstract: A phased array antenna comprises an array of reflective cells, each cell being defined by a wall positioned within the array the wall arranged to define a waveguide, and having a moveable reflector positioned within the wall. Each reflector is arranged such that it is not in electrical contact with its respective wall and such that, in use it can be moved to tune the antenna. A feed and subreflector are positioned within the array and arranged to transmit and/or receive electromagnetic signals to and/or from the array.
