The solution comprises a VectorStar VNA that sweeps from 70kHz to 220GHz with patented NLTL technology-based millimetre-wave (mmWave) extenders. The mmWave extenders convert up/down signals to 220GHz and are so small that they can be easily mounted on a robotic arm that performs a scan around the AiP in a pre-programmed, high-resolution step yielding accurate antenna radiation pattern measurements at D and G band frequencies. The robotic arm and the probe station are provided by MPI and ATV systems who excel in their respective domains of probe stations/probes and measurement automation expertise.
The AiP can be probed/fed from either the side of the antenna, which can be placed on a glass substrate or any other material, or it can be probed from the bottom so that the probing does not interfere with the radiation of the antenna. The special Titan Probes used for probing the AiP is connected to the VectorStar mmWave modules. They can be single ended or differential depending upon the application.
