WAVEGUIDE
Document Type and Number:
Japanese Patent JP2004048486
Kind Code:
A
Abstract:

To provide a waveguide that is constituted of two half split members and can be manufactured easily.

This waveguide 1 is constituted by joining the two half split members 2 and 3 which are split along H or E surfaces and formed of a resin or metal. In addition, this waveguide 1 has a trapezoidal, pentagonal, or hexagonal cross section in the direction perpendicular to its lengthwise direction. The half split members 2 and 3 are formed by using a molding inner frame and a molding outer frame. For example, the second internal surface 221 of the member 2 adjoining to the first internal surface 211 of the member 2 which is formed in parallel with the H-surface of the member 2 is inclined against the first internal surface 211 at an angle of ≥90.1° and <180° so that the molding inner frame may be removed easily from the member 2 during the course of forming the member 2.
