Abstract: Exemplary embodiments are disclosed of switching arrangements for antenna devices. Exemplary embodiments are also disclosed of antenna arrangements and portable radio communication devices including such switching arrangements. An exemplary embodiment includes a switching arrangement for an antenna device operational in at least two frequency bands. In this example, the switching arrangement generally includes a switching device that is switchable into at least a first state and a second state. The switching device includes at least a first port, a second port, and a third port. The first port is connectable to an antenna device. The second port is connected to the first port in the first state. The third port is connected to the first port in the second state. The switching arrangement includes an inductor connected between the first port and ground.
