1. A phase shift element comprising:
an antenna;
a first dielectric layer;
a ground plane mounted to a first surface of the first dielectric layer;
a reflecting circuit mounted to a second surface of the first dielectric layer, wherein the first surface is opposite the second surface;
a single antenna-reflector line connected between the antenna and the reflecting circuit through the ground plane and the first dielectric layer, wherein the antenna-reflector line is formed of a conducting material; and
an interconnect line connected between the antenna and the ground plane, wherein the interconnect line is formed of a conducting material,
wherein 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; and
wherein 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.
