Abstract
Modern mm-wave 5G links rely extensively on phased arrays to achieve high array gain for sufficient coverage. However, the proximity of antenna elements often results in element-to-element coupling, which leads to significant element-level antenna-impedance mismatches (i.e., poor VSWR), depending on element locations and beamforming settings. Such array VSWR, often rapidly changing due to fast beamforming, severely degrades mm-wave front-ends, reduces scan-angles, and renders DPD ineffective or intractable [1]-[3]. Show more
