Abstract (en)
[origin: EP0297328A2] In a multiple antenna arrangement having a plurality of antennas for antenna diversity, for reception preferably in the metric waveband (VHF), e.g. for a motor vehicle, having a heating panel arranged in the region of a window, e.g. a car rear window, with conductor parts arranged on the end for supplying the heating current, and with conductor parts to be heated arranged between them, at least three diversity antennas are provided and at least two of the diversity antennas have such conductor parts (4a, 4b, 4c, 4d) arranged on the end, and conductor parts (2a, 2b) to be heated arranged between them, and a terminal pair. In this arrangement, each terminal pair has an earth connection point (14a, 14b) and a conductor part connection point (5a, 5b) and the conductor part connection points of the diversity antennas are arranged such that, in RF terms, they are largely decoupled from one another. Elements (6a-d) blocking RF power are provided in the heating current supply lines, and at least one antenna conductor connection point is provided as a part of a further antenna in the part of the surface of the window which is not covered with conductors, together with a connection terminal pair, formed by an earth connection (52, 14c, 14d) and the antenna conductor connection point (5c, 5d), and the antenna conductor with the connection terminal pair is arranged such that each diversity antenna is largely decoupled from the others in RF terms. <IMAGE>
