ABSTRACT:
A diversity antenna arrangement to reduce cost and the number of switching operations between different antennas includes an antenna changeover switch for switching between antennas, and an evaluation circuit for evaluating reception quality of a signal derived from a signal received from at least one of the antennas and conveyed to a receiving device via the antenna changeover switch. The evaluation circuit emits an evaluation signal based on the determined reception quality. A control device drives the antenna changeover switch based on the evaluation signal. A weighting device, using a first coefficient, weights the signal conveyed to the receiving device via the antenna changeover switch, and using a second coefficient, weights a signal received from at least one further antenna. A summing circuit adds the weighted signals. A regulating circuit generates the coefficients to minimize the temporal amplitude fluctuations of the composite signal, which is evaluated by the evaluation circuit.
