Abstract:
An antenna device includes first antenna units, second antenna units, first switching circuits and second switching circuits. The first antenna units generate radio frequency (RF) signals operating at a first frequency. The second antenna units generate RF signals operating at a second frequency. The first frequency is larger than the second frequency. The first switching circuits selectively enable at least one of the first antenna units. Each of the first switching circuits includes a first switch element and a second switch element. The first switch element is connected in parallel with an inductor. The second switch element is connected in parallel with another inductor. The second switching circuits selectively enable at least one of the second antenna units.
