DIELECTRIC SUPPORT OF COAXIAL TRANSMISSION LINE Russian patent published in 1995 - IPC

FIELD: SHF devices. SUBSTANCE: dielectric support of coaxial transmission line has dielectric washer 1 with through holes 2 having form of arc-shaped slits which longitudinal walls are coaxial to side surface of dielectric washer and are limited by radii forming central angle α. Sum of central angles a equals 2π. Dielectric support functions in the following way. Width of slits chosen by means of formula equivalent for dielectric permittivity of cylindrical multilayer capacitor such that wave resistance of coaxial line in section of dielectric support is equal to wave resistance of regular coaxial line. Diameters of concentric circumferences forming slits are so chosen that rigidly of washer is provided. Dielectric washer enables high level of matching within wide frequency range to be ensured. EFFECT: reduced reflection. 2 cl, 2 dwg
