Researchers from Southeast University have developed a compact, dual-band, dual-polarized phased array for B5G/6G millimeter-wave communication. The array integrates four independent beamforming ...

Optical phased arrays (OPAs) and beam steering technologies represent a transformative approach in photonic systems, offering rapid and reliable control of light propagation without reliance on ...

This white paper explores basic phased-array theory and the design considerations behind next-generation antenna systems. It examines the new capabilities recently added to the NI AWR Design ...

Micromachining can be used to create a infra-red beam-forming phased array, according to engineers at University of California, Berkeley, who have made a 160 x 160 array on a 3.1 x 3.2mm die that can ...

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 ...

In Part 1, we introduced the phased array concept, beam steering and array gain. In Part 2, we presented the concept of grating lobes and beam squint. In this section, we begin with a discussion of ...

Analog Devices is aiming at X-band and Ku-band phased-array antennas with an active analogue beam-forming chip that includes four channels of transmit and receive gain and phase control, plus a ...

The current network of weather radars in the United States was installed in the late 1980s and into the 1990s. There are nearly 160 weather radars in the network. The radars are the NEXRAD WSR-88D ...

The SBX, shown here on a cargo vessel in Texas, practiced two days of "weather avoidance" when Hurricane Emily arrived in the Gulf of Mexico during 2005 testing. The range of the array inside the dome ...
