5G Antenna Characterization in the Far-Field

5G Antenna Characterization in the Far-Field

5G mobile devices and base stations will be operating antenna arrays and beam-steering techniques in the millimeter-wave region. The question of the far-field measurement distance is particularly critical for such technologies as a larger over-the-air test range means dynamic range issues and significantly larger cost. The traditionally used formula for the far-field distance aims at…
