一种紧凑型的宽频带单脊波导功分器
Compact broadband single-ridge waveguide power divider
摘要
Abstract
A broadband, miniaturized single-ridge waveguide power divider structure was presented. The branch waveguide adopted standard single-ridge waveguide, which expanded the dominant mode bandwidth of transmission mode under the condition of maintaining high power capacity. At the T-junction, a capacitive metal flat plate was connected with the branch single-ridge waveguide to form a broadband reactive tuning element, which effectively realized the broadband matching of the T-junction under the expansion of the main mode bandwidth. In order to connect with standard devices, a single-ridge waveguide-standard rectangular waveguide conversion device was designed. The impedance bandwidth of the conversion device was consistent with the T-junction by multi-step matching. This structure was simulated and optimized by HFSS. The simulation result shows that the return loss is below –20 dB in the range of 25-40 GHz, the signal variation is better than 0.04 dB and the power divider obtains a 46.2% of effective bandwidth. Compared with the standard rectangular waveguide power divider, the actual internal dimension of the single-ridge waveguide power divider is reduced by 38%. The single-ridge waveguide power divider takes the advantages of low loss, miniaturization and wide bandwidth, which can be widely used in radar, antenna and power amplifier.关键词
