An antenna includes a radiating element on a forward-facing surface of an underlying reflector, and a multi-element planar broadband lens in front of and within a radio frequency (RF) transmission path of the radiating element. The broadband lens includes first lens elements having first RF characteristics and second lens elements having second RF characteristics, which are different from the first RF characteristics. The first lens elements are arranged as a plurality of the first lens elements, which are encircled by an array of the second lens elements. Each of the first lens elements includes a first LC circuit, and each of the second LC circuits includes a second LC circuit with a smaller inductance relative to the first LC circuit.

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.

Disclosed is a radiator assembly configured to operate in the range of 3.4-4.2 GHz. The radiator assembly comprises a folded dipole with four dipole arms that radiate in two orthogonal polarization planes, whereby the signal of each polarization orientation is radiated by two opposite radiator arms that radiate the signal 180 degrees out of phase from each other. The radiator assembly has a balun structure that includes a balun trace that conductively couples to a ground element on the same side of the balun stem plate. The combination of the shape of the folded dipole and the balun structure reduces cross polarization between the two polarization states and maintains strong phase control between the opposing radiator arms.

A base station antenna includes first and second reflectors that are movable relative to each other, and each of the first and second reflectors includes a plurality of radiating elements on a main reflector surface thereof. A third reflector is movably coupled to the first and second reflectors, and movement of the third reflector causes the first and second reflectors to move relative to each other. A drive mechanism is utilized to move the third reflector and includes a drive shaft, an actuator configured to rotate the drive shaft, and a threaded shaft coupled to the drive shaft and configured to rotate in response to rotation of the drive shaft. Rotational movement of the threaded shaft causes linear movement of the third reflector. A control unit, such as a remote electrical tilt (RET) controller controls the actuator to rotate the driveshaft.
