Antenna device

Abstract

An antenna device includes a first substrate, plural antenna elements, a second substrate, plural circuit units, plural circuit patterned layers and plural conductive structures. The first substrate is defined with a first surface and a second surface opposite to each other. The antenna elements are arranged on the first surface of the first substrate. The second substrate is connected to the second surface of the first substrate. The circuit units are arranged at the second substrate. The circuit patterned layers are arranged on the first substrate and the second substrate. The conductive structures are connected to at least ones of the circuit patterned layers. One of the circuit patterned layers includes plural induction units corresponding to the antenna elements, at least ones of the circuit units correspond to the induction units, and the induction units and the antenna elements transmit a carrier signal to each other by electromagnetic induction.
