Optically tunable microwave antennas for 5G applications

Multiband tunable antennas are a critical part of many communication and radar systems. New research by engineers at the University of Bristol has shown significant advances in antennas by using optically induced plasmas ...

A view inside ESA's cavernous Hertz chamber for radio-frequency testing of satellites, which will be on show to the public during this Sunday's ESA Open Day in the Netherlands.

Many antennas, multiple benefits

A concept that balances large-scale installations of low-cost and low-power antennas to boost cellular coverage in difficult environments will also provide better connectivity to more users. Developed by A*STAR, this new ...

Building better high-speed robots with the help of cockroaches

Love them or hate them, cockroaches are notoriously good escape artists and can flee at astonishing speeds. However, this speed can make it difficult to sense the world around them: 'When animals move slowly they rely mostly ...

Inflatable antennae could give CubeSats greater reach

The future of satellite technology is getting small—about the size of a shoebox, to be exact. These so-called "CubeSats," and other small satellites, are making space exploration cheaper and more accessible: The minuscule ...
