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.

Abstract: The present disclosure provides an antenna system, including a mainboard having a system ground, a metal frame disposed around the mainboard and being closed-loop without any breakpoints, a first wire, a second wire, a third wire, a feed terminal, and a ground terminal. The system ground is electrically connected to the metal frame. The first wire is connected to the feed terminal and is opposite to and spaced apart from the metal frame, so that the first wire forms a first antenna unit. The second wire is connected to the ground terminal and is spaced apart from the first wire, and the second wire and the first wire are at least partially opposite, so that the second wire and the first wire are coupled with each other, to form a second antenna unit.

Abstract: The antenna unit includes a first radiation patch, a feed structure, a second radiation patch, a ground plate, and an insulating dielectric layer. The first radiation patch is electrically connected with the ground plate. The feed structure includes a feeding post and an outer ring. The feeding post passes through the insulating dielectric layer and the ground plate, and one end of the feeding post is connected with the second radiation patch, the other end of the feeding post extends out of the ground plate. The ground plate is provided with a first avoidance hole for avoiding the feeding post, and an outer wall surface of the outer ring is connected with an inner wall surface of the first avoidance hole. The feeding post is coaxial with the feeding outer ring and arranged separately from the feeding outer ring. A dual-frequency and a dual-polarization are formed in the present disclosure.
