Abstract
An antenna device includes antenna units, transmission lines and switching circuits. The antenna units are used to be operated in a directional mode or an omni-directional mode. The transmission lines are coupled to the antenna units. The switching circuits are coupled to the respective transmission lines, and are used for selectively connecting the transmission lines according to control signals. At least one transmission line is disconnected when the antenna units are operated in the directional mode. All the transmission lines are connected when the antenna units are operated in the omni-directional mode.
