Abstract

In this paper, we present a THz near-field scanning system for antenna measurement. It entails software and hardware designs and system integration. Software design includes motor control, near-field data acquisition and near-field to far-field transformation. For hardware design, a 3D printed absorber is incorporated into the THz probe to reduced ripples in the measured data. For system integration, we employ a phase detection technique for probe alignment. In principle, the system can work up to 1.1 THz but is currently limited to 0.75 THz due to the availability of the required open-ended waveguide probe.
