Validation of OTA Measurement Setup At 28GHz Using A Plan Wave Generator

In this paper, we thoroughly test and validate the complete active signaling measurement setup using a Plane Wave Generator (PWG), Radio Communication Tester (RCT), and a well-known antenna standard. The results of our study demonstrate excellent agreement between the Equivalent Isotropic Radiated Power (EIRP) measurements obtained using the active setup with the PWG, and those obtained using a passive measurement system employing the multiple probe spherical near-field technique. Furthermore, the Total Radiated Power (TRP) values derived from the active setup with the PWG are within expected uncertainty to the measured conducted power at the Horn input port. The measurements are done at 28GHz. The measured TRP using active OTA and conducted measurements are within 0.31 dB (6.9%) difference. This robust comparison illustrates the reliability and confidence in utilizing the PWG-based active measurement system.
