Abstract
Designing phase shifters having small insertion loss and footprint for mm-wave applications is challenging. The disclosed methods and devices provide solutions to overcome such challenge. Devices based on limited ground coplanar waveguide structure are also disclosed wherein the 180° phase shift is created using through and changeover mm-wave switches.
