PARIS — The Intelsat New Dawn satellite launched April 24 has been unable to deploy its C-band reflector antenna, depriving the satellite of half its intended functionality, because the antenna’s ...
GPU-accelerated electromagnetic simulation is redefining how engineers design and validate antennas in complex, electrically ...
Engineers at Los Alamos National Laboratory are reinventing the mirror, at least for microwaves. Their invention could replace the familiar satellite dishes and microwave horns seen on rooftops and ...
Dual reflector antennas are considered as pencil beam antennas that can produce radiation identical to searchlight. Cassegrain Reflector Antenna Design consists of various effects caused by blockage ...
An advanced antenna reflector designed and built by Harris Corporation (HRS) has been successfully deployed in space onboard the Sirius FM-6 satellite which was designed and built by Space ...
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 ...
Seventeen days after NISAR’s launch from southeastern India, an essential piece of science hardware has unfurled in orbit. Spanning 12 metres, the drum-shaped antenna reflector on the NISAR (NASA-ISRO ...
A 6m-diameter composite reflector frame that could be collapsed into a 1.83m by 0.36m envelope for launch, weigh less than 13 kg and then deploy as expected in the zero-gravity LEO environment. A ...
Designing equipment that meets stringent size and mass restrictions for use on aircraft brings extra challenges for instrument developers, as Tamara Clelford explains Antennas are used for a huge ...
