Abstract
The band widening circuit consists of a section of microstrip with adjustable characteristic impedance connected in series with an adjustable capacitor both connected to the three interleaved conductive pattern of the circulator. The preferred mode consists of a microstrip with air as dielectric and a conductive plate movable with respect to the conductive strip in the shape of a spiral. The capacitor is a conductive plunger movable in a conductively coated recess of a substrate for the conductive strip of the microstrip line section.
