A phased array, in antenna theory, is an array of antennas in which all of the phases of each signal that feeds each antenna are set in such a way that the effective radiation pattern of the entire array is set toward the desired direction and that the signals emanating toward undesired ...
Why use a phased array antenna for radar applications? As mentioned above, PARs do not have moving parts, which is enormously beneficial for radar applications. First and foremost, the field of view can be changed in a few microseconds. This is significantly faster than a conventional rotating ...

There are different kinds of antenna arrays. A linear array has one phase shifter, and antennas arranged in a line. The rays can be deflected in only one horizontal or vertical plane, but a planar array can steer beams in two planes. This type is more complex and each antenna includes a...

but these antenna arrays tend to be large and very expensive. Applying this technology to commercial wireless — where the antenna arrays will need to be much smaller and less costly — introduces many new challenges. There is a long list of 3GPP required tests for base stations, including rad...
