PURPOSE:To prevent crack of a magnetic substance, by increasing slightly the shape of a pair of magnetic substances holding an inner conductor comprising a triplate line in-between larger than the inner conductor. CONSTITUTION:The shape of a part of the magnetic substances 6, 7 in contact with an inner conductor 1 is formed into Y shape by shaping an outer circumference of a sector being a circle divided equally into three in a recessed circular arc so as to be slightly larger than the shape of the inner conductor 1. The circulator is assembled by placing the magnetic substance 6, the inner conductor 1 and the magnetic substance 7 in order on a ground conductor 3a fixed with a magnet 5a, placing a ground conductor 2b fixed with a magnet 3b on the magnetic substance 7 and tightening and fixing them with screws 4a- 4c. Since the magnetic substances 6, 7 are shaped into the Y shape, the effect of bending of the ground conductors 3a, 3b is less, allowing to prevent the destruction of the magnetic substances. |
