Abstract: 

A new slide-screw impedance tuner structure uses multi-section, disc-shaped, rotating metallic
probes. This ensures probes covering multiple frequency bands to be served using a single
vertical control mechanism, instead of multiple axes, motors, motor control and double or triple
carriages. Additional benefits are high resolution in the area where the gap between center
conductor and probe is small (high GAMMA), smooth increase of proximity between probe and
center conductor (basic anti-corona form) and the possibility to compensate for the negative
phase slope at higher GAMMA, native to traditional slide screw tuners.
