Square waveguide line

Abstract

Abstract PURPOSE:To efficiently radiate power in phase through the power radiation slot by connecting a horn waveguide to a square waveguide via a power supply aperture and providing the power radiation slot radiating power in phase. CONSTITUTION:Plural power radiation slots (slot holes) 15 are formed nearly concentrically to a square metallic plate 3 of a couple of metallic plates 3, 4. Then metal-made circumferential walls 1, 2, 7, 8 connecting the circumference of the square metallic plates 3, 4 are provided to form a square waveguide space S surrounded by the square metallic plates 3, 4 and the metal-made circumferential walls 1, 2, 7, 8 and a horn waveguide 5 as a feeding means is connected to the power supply aperture 20 formed in the middle of the square metallic plate 4. In supplying power to the square waveguide space via the power supply aperture 20, the feeding power is split into two in axial-symmetrical direction. Thus, the power in phase is radiated in the axial symmetry main lobe even when the frequency is changed more or less through the bidirectional power radiation slots 15.
