Probe-Based Antenna Measurements at Sub-THz Frequencies

In this work, we integrate a probe platform and an over-the-air chamber to realize a probe-based antenna measurement system at sub-THz frequencies. Only one-time probing is needed to measure the S parameters and 3D radiation pattern. This probing operation is suitable for antenna-in-package modules where the feed point is at the opposite side of antenna. In addition, a sub-THz reflector is carefully designed for compact antenna test range so that the far field condition can be fulfilled in a small chamber.
