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 ...

Preventing adversaries from interfering with communications is crucial to national security. Tactical satellite communications (SATCOM) focus on securing reliable communications channels against ...

This article originally appeared in the Sept. 2, 2019 issue of SpaceNews magazine. Satellite operators ranging from lean startups to powerful defense agencies are experimenting with flexible materials ...

Why a reflective array offers benefits compared to active elements in a high-density array. How a binary phase-control scheme is used in place of conventional phasing for extremely low power, ...

In the last decade, there has been an expectation that increasing amounts of complex data be delivered faster ― and at higher quality ― through the use of revolutionary antenna systems. To expedite ...
