Abstract
The present invention concerns a front-end circuit (FEC) that is connectable to at least two radiators (RADM, RADD), wherein the front-end circuit (FEC) comprises sub-circuits (SC) and each sub-circuit (SC) is associated to one radiator (RADM, RADD). Further, each sub-circuit (SC) comprises a signal path (SP), an antenna port (AP) that is electrically coupled to the signal path (SP) and connectable to the radiator (RADM, RADD), a grounding port (GP) that is connectable to the radiator (RADM, RADD), a ground termination circuit (GTC), and a grounding switch (GS) that is electrically coupled to the grounding port (GP) and to the grounding termination circuit (GTC).
