Abstract

An antenna device includes first to third antenna units and a feed-in line. An angle between the second antenna unit and the first antenna unit is substantially equal to 90 degrees. An angle between the third antenna unit and the first antenna unit is substantially equal to 90 degrees. The feed-in line crosses over each of the first to third antenna units in a view, and is configured to turn on and turn off each of the first to third antenna units. The first antenna unit and the second antenna unit are configured to generate a first polarized signal, the third antenna unit and the second antenna unit are configured to generate a second polarized signal, and the first polarized signal and the second polarized signal have different polarizations.
