Long used in expensive military radar and satellite applications, electronically scanned phased-array-antennas offer performance that could benefit a variety of other applications, such as commercial ...

A new phase shifter does not need clean-room facilities for fabrication, so is inexpensive to manufacture. The liquid-metal enabled phase shifting elements have a 'passive' nature, unlike the 'active' ...

Phased array technology is far from new. Phased-array antennas have been used for decades in a variety of military applications. Now, however, their use in 5G systems in the Band 2 frequency range is ...

One limit to the use of phased array radars is the physical size of the arrays. Their large size prevents their use in collision avoidance systems in automobiles and other platforms that could benefit ...

(Nanowerk News) Chip-scale silicon photonics optical phased array (OPA) is widely used in free-space communication. However, due to the limitation of optical device design and manufacture, the ...

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, ...

A new type of high performance ‘phase shifter’ for use in advanced phase array antenna systems has been developed at the University of Birmingham. Researchers led by Dr Yi Wang from Birmingham’s ...
