In a phased array, time delay is the quantifiable delta needed for beam steering. But time delay can also be emulated with a phase shift, which is common and practical in many implementations. We will ...

This is the second article of our three-part series on phased array antenna patterns. In Part 1, we introduced the phased array steering concept and looked at the influencers on array gain. In Part 2, ...

These PAA systems use multiple phase shifters to provide the controlled phase increments that steer the radiation beam (see picture ... that controls the phase shift via a liquid-metal material ...

A new OPA design OPAs perform beam steering by electronically controlling light’s phase profile to form specific light patterns. Most OPAs use an array of waveguides to emit many beams of light ...
