Abstract:
An antenna circuit, comprising:at least two signal paths; an antenna connection device connected to an output via the at least two signal paths and to which at least one first antenna is capable of being attached, wherein: a second antenna signal that has been received and then conveyed via a second one of the at least two signal paths is attenuated by a predetermined attenuation value in comparison with a first antenna signal that has been received and then conveyed via a first one of the at least two signal paths; an analyzer unit for determining a level of a weighting signal derived from magnitudes of at least one of the first antenna signal and the second antenna signal provided to the output; and an operating device for connecting only the first one of the at least two signal paths to the output when the determined level of the weighting signal is below a first predetermined level, and for connecting only the second one of the at least two signal paths to the output when the determined level of the weighting signal is above the first predetermined level.
