Abstract
An antenna device includes a first substrate, a second substrate, a radiation portion and a cross-shaped exciter. The first substrate has a first top surface. The first substrate is stacked on the second substrate. The second substrate has a second top surface and a bottom surface. The second top surface faces away from the bottom surface. The radiation portion is disposed on the first top surface, and includes a first radiation component, a second radiation component, a third radiation component and a fourth radiation component. The first radiation component and the fourth radiation component are arranged on the first top surface symmetrically along a diagonal of the first top surface. The second radiation component and the third radiation component are arranged on the first top surface symmetrically along another diagonal of the first top surface. The cross-shaped exciter is disposed on the top surface.
