Preliminary Assesment Of Millimeter Wave Plane Wave Generator For 5g Device Testing

In this paper, early performance assessments on a newly developed plane wave generator (PWG) at millimeter wave frequencies are reported for the first time. The PWG is integrated in an automated system suitable for 5G testing. Far-field radiation from devices such as pattern, beam pointing, and typical over-the-air (OTA) parameters can be measured in 3D space. Devices are positioned in the quiet zone (QZ) using a RF transparent positioner. Live person testing is feasible, using a chair placed in the system such that the device including head and upper torso of the test person is within the QZ.The PWG based system is described in this paper, including a preliminary evaluation of measurement performance and accuracy at system level. The assessment is based on system simulation, measurement post-processing, and actual test on a pilot system. The PWG technology discussed in this paper is currently being integrated as a standard product.
