1. A circuit, comprising:

  • a sensing circuit for a first antenna and a second antenna which concurrently participate in a communication, wherein the sensing circuit comprises an adjustable characteristic that is based on a proximity of an object to the first or second antenna used for transmission of a transmit signal, and wherein the sensing circuit comprises the first antenna or the second antenna;

    an evaluation circuit coupled to the sensing circuit, the evaluation circuit being configured to monitor the characteristic of the sensing circuit and to determine whether the characteristic fulfills at least one of a predetermined set of criteria; and

    a switching element configured to operatively couple the evaluation circuit to the first antenna during a first time interval and to operatively couple the evaluation circuit to the second antenna during a second time interval.
