<p>An antenna array (10) comprises a ground plane (12) and at least a first antenna array part (14). The first antenna array part comprises a first antenna (22) and a second antenna (24). Each of the first antenna and the second antenna is of generally truncated triangular shape and has a respective main axis (26) extending between a respective narrower end (30) and a respective wider end (34). The respective narrower ends are mutually facing one another and provide respective feed points for the first and second antennas. Each of the first antenna and the second antenna has a first part (40) diverging axially and linearly away from the ground plane in a direction from the narrower end towards an apex (38) and a second part (42) which extends in converging relationship with the ground plane from the apex in a direction away from the respective narrower end.</p>
