PURPOSE:To attain the connection of different polarized waves, by inserting a metallic plate having slits symmetrical over respective polarized waves on bonding surfaces of two rectangular waveguides and using the slot mode propagation oscillated in response to the wavelength of electromagnetic waves propagated on the slits. CONSTITUTION:A thin metallic plate having Z-shaped, step-shaped and key- shaped slits is provided between two waveguides 11 and 12 in place of a metallic plate 13. In each slit, lateral and longitudinal total length of the slits are equal and they are proportional to the propagated wavelength. The slits are produced on a copper plate having 50mum thickness with the etching method. In the operation, each slot is used as the slot coupling to enclose the electromagnetic energy resonated in the slits, and the electromagnetic waves are converted into polarized waves having the phase by 90 deg., by using the resonance energy as interposition. |
