Microswitch beam-steering grid [PDF]
International Conference on Millimeter and Submillimeter Waves and Applications 1994, 2017 We propose new microswitch beam-steering grids to operate at 90 GHz and 240 GHz. The microswitch beam-steering grid has potential advantages over mechanical-scanning devices or active beam-steering reflectors based on diode grids such as lower loss and simple control circuits.
