Abstract: Technologies directed to a mechanically steered antenna with improved efficiency are described. One antenna includes a first reflector, a second reflector, and an antenna feed element. The second reflector is located on a reflecting side of the first reflector. The second reflector is offset from the first reflector. The second reflector receives an electromagnetic signal from the antenna feed element and outputs an inverted electromagnetic signal corresponding to the electromagnetic signal. The first reflector receives the inverted electromagnetic signal and outputs a collimated beam corresponding to the inverted electromagnetic signal. The antenna further includes a mechanism coupled to the first reflector. The mechanism rotates the first reflector about a first axis. The first axis is along a direction of the inverted electromagnetic signal.
