Abstract: A dual polarization antenna that includes a conductor and two dipoles. The conductor has four radiation arms, each radiation arm forms a branch of the conductor, and two adjacent radiation arms are connected by a connection bridge. The two dipoles are arranged in a cross manner to form four sectors, one radiation arm is arranged in each sector, and the connection bridge is disposed above or below the dipole between the two radiation arms connected by the connection bridge.

Abstract: A multi-band dual-polarized antenna includes a first radiator and a second radiator, each having a rotationally symmetric structure. The first radiator has two feeding ports that are 90° rotationally symmetric with respect to a geometric center of the first radiator. The second radiator is annular, the first radiator and the second radiator are coplanar, the first radiator is disposed in the second radiator, and an annular gap is provided between the first radiator and the second radiator.

Abstract: Embodiments of the present invention disclose a dipole antenna and a wireless terminal device, which relate to communications technologies and enable an antenna to have a relatively high performance and a relatively low production cost. The dipole antenna includes a first radiation arm, a second radiation arm, and a balun. The first radiation arm and the second radiation arm are both soldered on a dielectric substrate. The first radiation arm and the second radiation arm are separately connected to the balun electrically. The balun is electrically connected to a feeding point and a reference ground separately. The present invention may be applied to a terminal device.
