Contactless pin-flange adapter for high-frequency measurements
Paper i proceeding, 2012
We present a first contactless pin-flange adapter for high-frequency measurements based on gap waveguide technology. Conventionally, standard (WR) flanges are used, these require good electrical contact and are sensitive to small gaps. The pin-flange adapter has been fabricated and demonstrated for the frequency range 220-325 GHz. It shows similar or better results than a standard flange or a choke flange without requiring electrical contact. The pin-flange adapter has a lower noise level compared to the other flanges, almost 10 dB lower.
