The broadcast antenna was based on an active phased array, allowing it to steer without physical movement.

For instance, a phased array consists of two or more simple antennas which are connected together through an electrical network.

She has a keen interest in emerging radio astronomy technologies, including the use of phased array feeds.

But these antennas, often called "adaptive" or "phased array" systems, are a long way from home use.

Research is going on to achieve scanning of laser beams through phased arrays.

When phased arrays are used in sonar, it is called beamforming.

"Are you familiar with your concept of a phased array?"

The latter had the sound bar split into two units, with a phased array of three full-range drivers in each.

These early phased arrays, replaced around 1980, were responsible for the distinctive square-looking island.

In a conventional phased array the individual antenna elements are mounted on a flat surface.
