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. Simulations predict that a 4-bit controlled 10-layer microswitch beam-steering grid can have phase-shift resolution of 22.5° with a loss of 1.6 dB and a maximum phase error of 5° at 240 GHz.
