A metamaterial-based phase shifting element utilizes a variable capacitor (varicap) to control the effective capacitance of a metamaterial structure in order to control the phase of a radio frequency output signal generated by the metamaterial structure. The metamaterial structure is configured to resonate at the same radio wave frequency as an incident input signal (radiation), whereby the metamaterial structure emits the output signal by way of controlled scattering the input signal. A variable capacitance applied on metamaterial structure by the varicap is adjustable by way of a control voltage, whereby the output phase is adjusted by way of adjusting the control voltage. The metamaterial structure is constructed using inexpensive metal film or PCB fabrication technology including an upper metal island structure, a lower metal backplane layer, and a dielectric layer sandwiched therebetween. The varicap is connected between the island structure and a base metal structure that surrounds the island structure.

A beamforming antenna assembly is provided. The beamforming antenna assembly includes a mirror glass coated with a material, and a beamforming antenna disposed on a portion of the mirror glass. A pattern is formed on the portion of the mirror glass so that a beam radiated from the beamforming antenna passes therethrough.

A phase shift element includes an antenna, a first dielectric layer, a ground plane mounted to a first surface of the first dielectric layer, a reflecting circuit, and a single antenna-reflector line connected between the antenna and the reflecting circuit through the ground plane and the first dielectric layer. The antenna-reflector line is formed of a conducting material. The reflecting circuit is mounted to a second surface of the first dielectric layer. The first surface is opposite the second surface. The reflecting circuit is configured to reflect a signal received on the single antenna-reflector line from the antenna back to the antenna on the single antenna-reflector line. The reflecting circuit is further configured to be switchable between two different impedance levels that each provide a different phase shift when the signal is reflected by the reflecting circuit.
