Abstract

The invention belongs to the technical field of microwave communication, and particularly relates to an E-plane waveguide directional coupler and a 16-way waveguide power divider applying the coupler. The coupler comprises a first rectangular waveguide and a second rectangular waveguide which are constructed by E-plane coupling; and a ladder-shaped section for realizing a broadband phase supplementation function is arranged on the second rectangular waveguide, so that the low-amplitude volatility of each output port of a power divider with a high power division rate can be ensured. The 16-way waveguide power divider applying the coupler comprises two groups of waveguide E-plane power dividers, wherein a first E-plane waveguide directional coupler is arranged between the last-stage E-T branch waveguide of the first waveguide E-plane power divider and the previous three stages of power dividing networks, and a second E-plane waveguide directional coupler is arranged between two groups of waveguide E-plane power dividers, so that the amplitude uniformity and phase uniformity of the 16-way power divider can be effectively improved, the problem of large amplitude fluctuation of the power divider with a large power division rate can be synchronously solved, and a broadband designing requirement can be realized.

Description

technical field [0001] The invention belongs to the technical field of microwave communication, and in particular relates to an E-plane waveguide directional coupler and a sixteen-way waveguide power divider using the coupler. Background technique [0002] The power divider is an antenna feeder device widely used in modern communications. Traditional power dividers include Wilkinson, E-plane waveguide, H-plane waveguide, etc. The Wilkinson power splitter has a low profile and has the advantage of miniaturization, but the low power capacity and large dielectric loss of the microstrip transmission line limit its application in high-power requirements. The waveguide power splitter is favored for its excellent characteristics such as low loss, high power capacity and wide transmission bandwidth, and is widely used in high-power systems such as radar and satellite. In the waveguide power divider: the H-plane power divider is distributed by the wide side of the waveguide, and the...
