A wireless transceiver for a wireless communication network has an offset Gregorian antenna arrangement comprising a primary reflector dish, an electrically conductive reflector member comprising a secondary reflector and a conductive support wall, a planar array of antenna elements arranged as a feed for transmitting radio frequency signals to the secondary reflector and/or for receiving radio frequency signals from the secondary reflector and a conductive support block configured to support the planar array of antenna elements. The conductive support wall is connected directly to the conductive support block, and the conductive support wall is configured to be substantially perpendicular to the planar array of antenna elements.

Wireless transceiver having a high gain antenna arrangement

An antenna array assembly comprises a ground plate, a linear array of patch radiator elements disposed in a spaced parallel relationship with a first face of the ground plate and a first and second elongate passive radiator each comprising a plurality of conductive parts electrically isolated from the ground plate. The first and second elongate passive radiators are disposed symmetrically on either side of the linear array and parallel to a centre line of the linear array, on the same side of the ground plate as the linear array. At least some of the conductive parts of a respective elongate passive radiator are disposed in an arrangement having parallel ridges and grooves, in which, in a cross section in a plane parallel to the first face of the ground plate, the ridges extend towards the linear array and the grooves extend away from the linear array.

Antenna array assembly having high cross polar isolation

An antenna array assembly comprises a ground plate, a linear array of patch radiator elements disposed in a spaced parallel relationship with a first face of the ground plate, and a first, second, third and fourth elongate passive radiator, each comprising one or more substantially planar conductive parts which are electrically isolated from the ground plate. The first and second elongate passive radiators are disposed symmetrically on either side of the linear array and parallel to a centre line of the linear array, on the same side of the ground plate as the linear array. The third and fourth elongate passive radiators are disposed further from the linear array than are the first and second elongate passive radiators. Each of the third and fourth elongate passive radiators is narrower than and projects further from the ground plate than does each of the first and second elongate passive radiators.
