Title:
MILLIMETER WAVE ARRAY ANTENNA AND MOBILE TERMINAL
Document Type and Number:
WIPO Patent Application WO/2020/029661
Kind Code:
A1
Abstract:
Provided by the present invention is a millimeter wave array antenna, comprising metal ground layers and a sandwich metal layer, the sandwich metal layer comprises a top surface connecting the two metal ground layers along a long-axis direction of the sandwich metal layer and a bottom surface opposite to the top surface in parallel; the sandwich metal layer further comprises multiple antenna slots arrayed at intervals along the long-axis direction; the antenna slots penetrate the top surface and the bottom SURFACE and are connected with the two metal ground layers; the metal ground layers are provided with feed parts corresponding to each antenna slot; the feeding is performed through the feed parts; and each antenna slot and the metal ground layers and the sandwich metal layer surrounding the antenna slot form a slot antenna unit. Compared with the correlation technique, the present invention has the following advantages that the thickness is thin, the array antenna can be arranged at one end of the mobile terminal and occupies small thickness space, so that the electromagnetic wave concentration and radiation can be performed in forward and backward directions of the mobile terminal.
