Abstract
The present invention provides a millimeter wave array antenna and mobile terminal. The millimeter wave array antenna includes several antenna elements arranged in an array, each antenna element includes a first radiation patch, a second radiation patch, a first grounding plate, a power divider layer and a second grounding plate sequentially stacked from top to bottom. The first radiating patch is spaced apart from and coupled to the second radiating patch. The second radiating patch is provided with two feeding ends, and each feeding end is provided with two feeding notches. The power divider layer includes two transmission lines, each includes one input port and two phase-inverted output ports electrically connected to the input port. The two phase-inverted output ports are respectively coupling-fed two feeding notches of one feeding end. Each antenna element generates orthogonal polarization and dual-band resonance under excitation of two input ports.
