Abstract: An antenna array assembly comprises a ground plate (1), a linear array of patch radiator elements (2, 2a-2c) disposed in a spaced parallel relationship with a first face of the ground plate, and a first and second elongate passive radiator (3, 4), and a third and fourth elongate passive radiator (5, 6). Each passive radiator comprises one or more substantially planar conductive parts and is generally upstanding in relation to the first face of the ground plate is 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 (5, 6) are disposed further from the linear array than are the first and second elongate passive radiators (3, 4). Each of the each of the third and fourth elongate passive radiators (5, 6) is narrower than projects further from the ground plate than does each of the first and second elongate passive radiators (3, 4).

Abstract: An antenna array assembly comprises a ground plate (1, 14), a linear array of patch radiator elements (12a-12d, 11a-11d) disposed in a spaced parallel relationship with a first face of the ground plate, and a first and second elongate passive radiator (4, 5) each comprising a plurality of conductive parts (22a-22c, 23a-23c) each disposed to be generally upstanding in relation to the first face of the ground plate and being electrically isolated from the ground plate. The first and second elongate passive radiators (4, 5) 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.
