MIT researchers have developed a low-power scanning reflectarray antenna that improves anti-jamming satellite communications ...

Preventing adversaries from interfering with communications is crucial to national security. Tactical satellite ...

Reflectarray antennas combine the low profile of phased arrays with the simple geometry of reflectors to steer microwave beams for satellite links. They are composed of an array of scattering elements ...

DARPA's Radio Frequency Risk Reduction Deployment Demonstration (R3D2) is set for launch in late February to space-qualify a new type of membrane reflectarray antenna. The antenna, made of a ...
