摘 要 附 图: 摘 要:

PURPOSE: To change the frequency

characteristic of the filter through the

change in the height of a boss by forming

the boss separately from a square

waveguide so as to adjust the

height. ;CONSTITUTION: A thread hole 4

whose inner circumferential face is

threaded is provided to a wall of a wide

face of a square waveguide 1. A boss 5 is

a cylindrical screw whose outer

circumferential face is threaded and the

boss 5 is fitted by screwing it to the hole

4. Since the boss 5 is the cylindrical

screw, the insertion length to the thread

hole 4 is set freely. Thus, a desired

characteristic is easily obtained by

deciding the insertion length of the screw

5 while observing a passing and a

blocking frequency characteristic at the

electric adjustment.;COPYRIGHT:
