GigaSpike E-field-probe series

Schottky-diode-based active 3D near-field detection

The GigaSpike field probe series features low-invasive micro-antenna structures with integrated Zero-Bias Schottky-diodes for the active measurement of 3D field amplitude distributions. GigaSpike probes are offered for the frequency range from 25 GHz to 330 GHz. Thanks to their low-invasiveness they allow field measurements in close proximity to a device under test with only a minimal amount of back-scattering of the probed field and parasitic coupling effects. The GigaSpike probe is hence an ideal device for 3D vector field amplitude or power density measurements in the far- and near-field regions of millimeter-wave emitters, such as 5G Wigig antenna arrays. They can also be used to measure the radiation profile of photo-conductive Terahertz emitters.
