By combining the shared-cavity SIW Rotman lens and the shared-aperture antenna array, an orthogonal multibeam antenna capable of beam switching along two orthogonal planes is realized in the ...

Researchers revealed that the new low-power antenna is a type of millimeter-wave gradient index (GRIN) lens antenna. Although GRIN lenses have existed for over a century, the idea of developing a ...

Once considered an impossible concept, the new low-power antenna is a remarkable breakthrough in wireless technology. It’s a millimeter-wave gradient index (GRIN) lens antenna, a design rooted in over ...

Abstract: Millimeter wave operation in 5G base stations necessitates small cell size and advanced multi-beam capabilities. At millimeter waves, base station antennas must be highly compact, making ...

On the night of April 22, residents of Odessa heard something unfamiliar in the skies. It wasn’t the low, droning buzz that has become all too common since Russia began deploying its Geran-2 kamikaze ...

The focus will be on delivering a cutting-edge prototype GRIN lens antenna system for tactical 5G networks. The prototype will undergo field testing under the oversight of the U.S. Army's C5ISR ...
