LEO mega-constellations are expected to deploy thousands of satellites to provide broadband services with data rates ...

First, the payload requirements and problems faced by traditional multi-beam antenna are described. The user beam of the VHTS payload system mainly uses Ka-band multi-beam antenna for a large range of ...

Within a few years, researchers at the United Kingdom’s University of Birmingham could provide a new beam steering antenna usable with ultra-high radio frequencies that may be critical to future ...

If you could squeeze two or three times more cellular telephone conversations into the same amount of bandwidth, how much would that be worth? To most wireless companies, the answer is, millions of ...

PARIS — Startup satellite ground antenna manufacturer Kymeta on April 24 said it successfully established a link with a satellite delivering high-definition (HD) television signals in Ka-band using ...

The US Army and USAF are exploring how optical beamforming antenna technology can be used to transmit data at high speed over commercial and military satellites. UK-based satellite antenna company ...

Birmingham scientists have revealed a new beam-steering antenna that increases the efficiency of data transmission for ‘beyond 5G’ – and opens up a range of frequencies for mobile communications that ...

IEEE Spectrum – new antennas based on metamaterials, though, may soon rescue Web-addicted travelers from expensive connections in the air and elsewhere, and a group at the patent-licensing firm ...

5G will ultimately become a combination of many technologies. The New Radio, commonly known as 5GNR, will incorporate 64QAM and 256QAM modulations. Another significant aspect is beam steering, which ...

Leaky-wave antennas (LWAs) represent a fascinating class of radiating structures that utilise travelling waves whose energy gradually leaks along the antenna’s length, thereby producing highly ...

Written by Joseph Darlington, P.E. When building any radio system, the scarcest and most precious system component is not the radios, the antennas nor the towers, but available “clean” radio channels ...
