The disclosed structures and methods are directed to antenna systems configured to transmit and receive a wireless signal in and from different directions. An antenna for transmission of electromagnetic (EM) waves comprises a phased array and a metastructure. The phased array has radiated elements configured to radiate the EM waves. The metastructure is located at a phased array distance from the phased array to receive the EM waves at the first angle and to transmit the EM waves at a second angle, the second angle being larger than the first angle. The metastructure comprises three impedance layers arranged in parallel to each other and each impedance layer comprising a plurality of metallization elements. Each metallization element has a first dipole and a pair of first capacitance arms located on each end of the first dipole approximately perpendicular to the first dipole.

A dual-polarized antenna and a dual-polarized antenna assembly including the same are provided. A dual-polarized antenna includes a base board, feeding unit supported on the base board, and radiation plate supported on the feeding unit. The feeding unit includes a first and a second feeding boards arranged to cross each other on the base board. The first feeding board includes a first feed line configured to supply a first reference-phase signal to a first point on the radiation plate and supply a first antiphase signal having an antiphase relative to the first reference-phase signal to a second point on the radiation plate. The second feeding board includes a second feed line configured to supply a second reference-phase signal to a third point on the radiation plate and supply a second antiphase signal having an antiphase relative to the second reference-phase signal to a fourth point on the radiation plate.

The present disclosure describes strand mounts for small cell radios. A strand mount may include a top plate, a bottom plate, and opposing side plates that form a housing having an interior cavity dimensioned to fit around one or more small cell radios, a plurality of mounting members, each mounting member coupled to the top and bottom plates within the interior cavity and configured such that a small cell radio can be mounted thereto, and one or more mounting brackets. The strand mount has the dual-capability of being mounted either horizontally on a cable strand or vertically on a pole. Alternative strand mounts and strand mount assemblies are also provided.

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.
