Antennas installed at 18 U.S. high schools detected bursts of radio activity that can precede solar disturbances capable of ...

Results from an investigation into methods of modeling the radiation patterns of phased arrays that include the effects of radiative mutual coupling are presented. The approaches are based on either ...

SATCOM 17-21GHz receive and 27-31GHz transmit array panels for high-performance ground terminals, available in Q3 2025. A 24.25-27.5GHz 5G millimeter-wave dual-polarized 512-element antenna array ...

Testing, evaluating, and qualifying phased-array antennas bring new challenges to designers and developers in characterization, calibration, and production test. The cloud is expanding into space ...

Secondly, there is the impact that we can exert through beamforming the array, called the array factor (GA). The full array antenna gain pattern is the combination of the two factors, as shown in ...

In recent years, Sengupta’s lab has designed antenna arrays that help engineers make strides toward peering through matter, boosting communications in canyons of skyscrapers, putting a medical lab on ...

The electromagnetic compilation of antenna arrays with an N pattern is then reduced to a calculation on one reference cell with periodic walls in a new modal base. ... · Time required for ...

The array factor, GA(θ), was used for a 16-element linear array, with a λ/2 spacing, and a uniform radiation pattern. The total pattern is a linear multiplication of the element factor and array ...

Phased-array systems have many advantages over single antennas. One advantage of having multiple transmit and receive elements is that you can apply complex weighting to each element to form a beam.

Expanding on this theme, the radiation pattern of an array can be generated from the multiplication of the element pattern and the array factor. However, when an antenna gets deployed into an array, ...
