In this paper a probe based measurement setup is presented that allows the characterization of antennas in the frequency-range between 220 GHz and 325 GHz. The radiation pattern, as well as the gain and the return loss of the antenna under test (AUT) can be measured. The limits of the system in terms of accuracy and dynamic range are given. To demonstrate its functionality a 240 GHz patch-antenna on Gallium Arsenide (GaAs) substrate is measured. A comparison between simulation and measurement shows very good agreement.
