Latest Patents

Ji-Fu Ma holds a patent for a "Mechanically Steered Antenna with Improved Efficiency." This invention describes technologies directed to a mechanically steered antenna that includes a first reflector, a second reflector, and an antenna feed element. The second reflector is strategically located on the reflecting side of the first reflector and is offset from it. This design allows the second reflector to receive an electromagnetic signal from the antenna feed element and output an inverted electromagnetic signal. The first reflector then receives this inverted signal and outputs a collimated beam. Additionally, the antenna features a mechanism that rotates the first reflector about a first axis, which is aligned with the direction of the inverted electromagnetic signal.
