Millimeter wave array antenna and mobile terminal

Abstract

The present invention provides a millimeter wave array antenna including: two metal grounding layers and a sandwich metal layer between the two metal grounding layers. The sandwich metal layer includes a top surface, a bottom surface and a plurality of antenna slots. The top surface is connected with the two metal grounding layers along a long axis direction, the bottom surface is opposite to and in parallel with the top surface, the antenna slots space the array along the long axis direction, penetrate the top surface and bottom surface and are connected with the two metal grounding layers. The metal grounding layers are provided with feed parts at positions corresponding to each antenna slot, and, each of the antenna slots, the metal grounding layers and the sandwich metal layer forms a slot antenna unit.
