In this paper, a Ku-band corrugated feed horn antenna for a Cassegrain reflector is designed and optimized. The horn dimension parameters are optimized so that it has a radiation pattern with a ...

3-dimensional rendering of metamaterial lined feed horn antenna with low loss, low weight, and over an octave bandwidth for satellite communications shown with satellite. Cheaper, lighter and more ...

PARIS — The Intelsat New Dawn satellite, whose C-band reflector antenna has remained stuck in folded position since the satellite’s April 22 launch, also had trouble deploying its Ku-band antenna, a ...

TAMPA, Fla. — Spire Global said May 10 it is installing Ku-band antennas from fellow smallsat operator Kepler Communications on at least three satellites to offer higher capacity data services ...

New in-flight data and communications services on commercial airlines in the United States, Asia and Europe are driving development of smaller antennas with greater functionality for both data and ...

Metamaterials provide an unprecedented ability to manipulate electromagnetic waves and are an enabling technology for new devices ranging from flat lenses that focus light beyond the diffraction limit ...

Kymeta, the company reimagining satellite connectivity, has announced a major technological leap: simultaneously operating across both Ku and Ka satellite bands in a single, compact antenna – laying ...

Cheaper, lighter and more energy-efficient broadband devices on communications satellites may be possible using metamaterials to modify horn antennas, according to engineers. Cheaper, lighter and more ...
