Abstract

An antenna device disclosed by the present invention comprises an antenna unit, the antenna unit comprises a first substrate and a second substrate which are oppositely arranged, a phase shift region is formed in the overlapped region of the first substrate and the second substrate along the thickness direction of the first substrate, and the second substrate comprises a first step protruding out of the phase shift region along the first direction. A plurality of first bonding pads arranged in the second direction are arranged on the side, close to the first substrate, of the first step, the first bonding pads are located on the side, close to the first substrate, of the second substrate, the first direction intersects with the second direction, the first bonding pads are connected with the first connecting line, and the second bonding pads are connected with the second connecting line. And the first bonding pad receives a driving signal output by an external driving circuit through the first connecting line. According to the antenna device provided by the embodiment of the invention, the first bonding pad is arranged to receive the driving signal output by the external driving circuit through the first connecting line, so that the width of the first step is reduced, the size of the whole antenna device is reduced, and the miniaturization application of the antenna device is realized.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to an antenna device. Background technique [0002] The phased array antenna is an important radio device for transmitting and receiving electromagnetic waves. The phased array antenna controls the phase of the radio frequency signal of the antenna unit in the array antenna through a phase shifter to change the radiation direction of the antenna to achieve the purpose of beam scanning. [0003] However, the existing phased array antenna has the problem of large size, which is not conducive to the miniaturization application of the phased array antenna. Contents of the invention [0004] The invention provides an antenna device to reduce the size of the whole antenna device and realize the miniaturization application of the antenna device. [0005] An embodiment of the present invention provides an antenna device, including an antenna unit; [...
