Abstract: A multiband antenna device includes a first antenna, a second antenna, and a switch. The switch is connected with the first antenna and the second antenna, respectively, and it controls a conducting state between the first antenna and the second antenna.

In the invention, signals in different frequency bands can be received, and the volume of a design circuit can be reduced. Reflecting energy of the signals feeding in the antennas can be reduced by adjusting impedance values of the antennas to make the multiband antenna device achieve an optimized receiving and transmitting state.
