Support structure for coaxial transmission line using spaced dielectric balls

摘要

A support structure for a coaxial transmission line includes a plurality of groups of dielectric balls compressibly mounted between the inner and outer conductors of the coaxial transmission line, the balls being "locked" into position via recesses located in the outer face of the inner conductor with holes centrally located in the balls and aligned parallel with the longitudinal axis of the transmission line sewing to compression relieve the balls and improve the VSWR of the transmission line, and with seventy-degree V-grooves being located on either side of the recesses in longitudinal alignment with the coaxial transmission line, for further improving the VSWR by adding inductance to compensate for the capacitance added by the presence of the balls.
