Patent ID: 7295825

Claim:
A diversity antenna arrangement, comprising: a plurality of different antennas; an antenna changeover switch for switching between the different antennas to provide an output signal that represents a signal received from one of the different antennas; an evaluation circuit for evaluating a reception quality of a signal that is derived from a received signal of at least one of the different antennas and for generating an evaluation signal as a function of the reception quality; a receiving device to which the signal is fed via the antenna changeover switch; a control device for driving the antenna changeover switch as a function of the evaluation signal; a first weighting module that, using a first coefficient, weights the output signal of the changeover switch to provide a first weighted signal; at least one further antenna providing a further received signal; a second weighting module that, using a second coefficient, weights the further received signal to provide a second weighted signal; a summing circuit for producing a weighted composite signal by adding the first weighted signal and the second weighted signal; and a regulating circuit for generating the first coefficient and the second coefficient by minimizing a temporal amplitude fluctuation of an amplitude of the weighted composite signal, wherein: the evaluation circuit evaluates a reception quality of the weighted composite signal.
