Abstract
There is disclosed an antenna arrangement for a vehicle window, particularly suitable for reception of signals in the UHF band while minimising the effect of fast fading. The antenna comprises antenna elements which generate at least two orthogonal or largely orthogonal modes. In reception, one or other mode may be selected such that the antenna effectively operates as a diversity antenna. Alternatively, the two modes may be combined to tailor the polarisation and directional properties of the antenna. For transmission, the properties of the antenna can be tailored to interact favourably with a particular vehicle to which it is applied. These properties may be controlled by a suitable combining circuit.
