An antenna assembly, and a method of operating it, comprising at least two antennas each adapted to communicate at at least a predetermined wavelength, the antennas being positioned along a predetermined direction and extending at least 0.1 times the wavelength along the predetermined direction. The assembly further comprises an electrically conducting element positioned between two of the antennas and having an area which, projected on to a plane perpendicular to the predetermined direction, covers between 0.07 times the predetermined wavelength squared and 0.7 times the predetermined wavelength squared. This conducting element acts to increase the gain/sensitivity along the direction, whereby the antenna(s) may be dimensioned to have larger gain at large angles to the direction, so that an overall gain increase is seen. |
