An NPA, resembling its radiofrequency counterpart, consists of several typically identical optical antennas. Each antenna emits light of a specific amplitude and phase to form a desired far-field ...

Phased array antenna systems are at the cusp of ubiquity. We now see Multiple-Input Multiple-Output (MIMO) antenna systems on WiFi routers. Soon phased array weather radar systems will help to predict ...

How large-area electronics can be adapted to create a gigahertz phased-array antenna. The potential advantages of this approach versus discrete components. The test arrangement used and some test ...

The operation of ground stations and phased-array antennas. How SDRs are integrated into ground stations. Issues to be considered when incorporating SDRs into phased-array antennas. Examples of ...

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 ...

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 ...
