It can be difficult to align the antennas in an array in phase and amplitude so they can be used together effectively. As the number of antennas increase in an array, the test time to do the alignment increases drastically.
This application note addresses the challenge of aligning the antennas in an array precisely, while reducing test time. It also provides details on a multichannel, phase coherent test solution which can be customized to quickly and precisely align antenna elements in an active array, both in phase and amplitude.
