Abstract
889,752. Matching waveguide impedances. MARCONI'S WIRELESS TELEGRAPH CO. Ltd. Sept. 16, 1960 [Jan. 11, 1960], No. 914/60. Class 40(8). A waveguide power splitter comprises a common rectangular waveguide 11 forking in the E-plane into two bends 12, 13 which are initially of unequal dimensions in the E- plane and which are tapered or widened to an E-plane dimension at their open ends equal to half the E-plane dimension of the common guide 11. The H-plane dimensions of the three portions are equal and constant throughout. The ratio of the power in the two bends is equal to the ratio of their E- plane dimensions at the junction and impedance matching is obtained at the junction over a wide band of frequencies for a wide range of power ratios. In order to equalize the impedances at the open ends of the three sections, the E-plane dimensions are equalized either by providing the common waveguide with a tapered section 6 or by providing the bends with flared sections 5. The Specification describes a known T-junction powersplitter having a wedge arranged with its apex facing the stem of the T.
