Patent ID: 8837336

Claim:
An antenna arrangement, comprising: a first signal path connected to a first antenna; a second signal path connected to a second antenna; a third signal path that includes a measurement device configured to measure signal strength; a first directional coupler that couples the first signal path to the third signal path; a second directional coupler that couples the second signal path to the third signal path; and a plurality of filters that filter out signal components that are coupled by the antenna into the second antenna and by the second antenna into the first antenna; wherein the third signal path is split into first and second sub-signal paths; wherein the first sub-signal path is connected to the first signal path by the first directional coupler and the second sub-signal path is connected to the second signal path by the second directional coupler; wherein the third signal path has two diplexers that are arranged at input-side and output-side ends of the two sub-signal paths and connect the input and output sides of the two sub-signal paths to a respective common signal path; and wherein the two diplexers are connected to the measurement device.
