Abstract
A reception antenna arrangement for motor vehicles for the GHz frequency range that is formed as a combined system for the reception of circularly polarized waves and/or vertically polarized waves by a plurality of dipole antennas. Their length is not greater than ¾ of the wavelength. To form a diversity function, at least one switching or reversing device (2) is provided so that at least two signals that are different in terms of diversity and received from the dipole antennas are alternatively supplied to at least one antenna connection point for diversity reception so that one or several more favorable reception signals can be selected and provided to the antenna amplifiers.
Claims14
A reception antenna arrangement for diversity reception for motor vehicles for the GHz frequency range, for disposal over a conductive, horizontally oriented base surface for the reception of circularly polarized waves and/or vertically polarized waves comprising;
- a plurality of dipole antennas extending spatially not more than ¾ of the wavelength;
- at least one reversing device (2) coupled to said dipole antennas for receiving at least two signals of different diversity, and alternatively coupling said signals to at least one antenna connection point (5) for diversity reception, so that a more favorable reception signal (4) or a plurality of receptions signals (4) can be selected by said reversing device (2) to substantially reduce interference and enhance the quality of the received signals.
