    Abstract: RF circuitry, which includes a first main RF switching circuit and a second main RF switching circuit, is disclosed. The first main RF switching circuit is capable of providing an RF signal path between a first main RF port and a first selected one of a first RF antenna and a second RF antenna. The second main RF switching circuit is capable of providing an RF signal path between a second main RF port and a second selected one of the first RF antenna and the second RF antenna. The first main RF switching circuit includes a first pair of RF switches coupled in series between the first RF antenna and the first main RF port; a second pair of RF switches coupled in series between the second RF antenna and the first main RF port; a first shunt RF switch; and a second shunt RF switch.

    Abstract: According to one embodiment, an antenna device includes first and second split ring resonators and a power supply line. The first split ring resonator includes a conductor enclosing a first opening and having a first void separating a part of the conductor. The second split ring resonator is opposed to the first split ring resonator, including a conductor which encloses a second opening and has a second void separating a part of the conductor. The power supply line feeds power to the first or second split ring resonator. The first split ring resonator is not electrically connected to the second split ring resonator. The first void does not overlap with the second void in an opposing direction of the first split ring resonator and the second split ring resonator.
