Abstract
An antenna arrangement has a first signal path connected to a first antenna. A second signal path is connected to a second antenna. A third signal path includes a device that measures the signal strength. Directional couplers couple the first and second signal paths to the third signal path. Filters filter out signal components that are coupled by one antenna into the other antenna.
