Plane unequal-power-division waveguide H-T power division network

Abstract

The invention relates to a plane unequal-power-division waveguide H-T power division network which comprises a plurality of equal-arm-length equal-power-division waveguide H-T power dividers and a plurality of equal-arm-length unequal-power-division waveguide H-T power dividers. Each equal-arm-length unequal-power-division waveguide H-T power divider comprises a waveguide input arm, a first waveguide output arm, a second waveguide output arm, a power distribution diaphragm, an impedance phase position adjusting block and an impedance tuning diaphragm, wherein the introduction of the impedance phase position adjusting blocks enables the equal-arm-length unequal-power-division waveguide H-T power dividers to be equal in arm length and enables the equal-arm-length unequal-power-division waveguide H-T power dividers to still meet requirements when the power division is large. The designed plane unequal-power-division waveguide H-T power division network is located in the same layer, the longitudinal dimension is small, therefore, the structure is simple, and the manufacturing cost is low. The lateral dimension is compact, and therefore the plane unequal-power-division waveguide H-T power division network is suitable for occasions with the limited space.

Description

technical field [0001] The invention relates to a planar unequal power dividing waveguide H-T power dividing network, which can be used as a feeding network for microwave circuit devices and array antennas. Background technique [0002] Whether it is used as a microwave circuit device or an antenna, a low-loss feeding network is required, and the waveguide feeding network is the best choice for a low-loss feeding network. [0003] The general waveguide feeder circuit is formed by cascading several equal power dividers and unequal power dividers, and the commonly used unequal power dividers usually use unequal arm length and unequal power divider waveguide H-T power dividers. The equal arm length and unequal power splitter waveguide H-T power splitter realizes the equal phase output of the two waveguide output ports of the power splitter by changing the length of the output arm, so the lengths of the two waveguide output arms are not equal, because the unequal arm length does...
