Grooved waveguide shorting block and method of assembly

摘要

A waveguide or waveguide phase shifter is terminated with a short circuit provided by a rigid conductive block which is sized to be a close tolerance fit within the waveguide. The block has grooves in its faces adjacent to the waveguide walls. The walls of the waveguide are deformed to project into these grooves to permanently secure the waveguide to the block.
