Abstract: In this letter, a 10 × 10 conformal reflectarray antenna (RA) operating at 9 GHz is designed and fabricated based on flexible materials. By controlling the operating state of the p-i-n diode ...

Keeping satellite communications secure is becoming more important as space becomes increasingly crowded. Military and ...

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 ...

Anywaves marks a significant milestone in the space industry by becoming the world’s first commercial equipment provider to deploy a Reflectarray in orbit. This achievement follows Anywaves’ selection ...

High-frequency signals, like those used in 5G communications, are reflected by impedance discontinuities. Their shorter wavelengths can change their impedance. When a signal arrives at an impedance ...

Abstract: We present an electronically reconfigurable reflectarray capable of performing 2-D beam-scanning. This reflectarray uses an electronically reconfigurable unit cell, consisting of an antenna ...
