MIT researchers have developed a low-power scanning reflectarray antenna that improves anti-jamming satellite communications while reducing size, weight and energy consumption for low-Earth orbit ...

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

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 ...

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 ...

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: In this letter, a reflectarray antenna with a small focal diameter ratio (F/D) is presented. It is found that when the F/D is extremely small, the phase constant used in calculating the ...

Abstract: This letter presents a versatile reconfigurable reflectarray that integrates with solar cells. The solar cell serves as the reflectarray element and energy harvesting cell, simultaneously ...
