摘要

本文采用补偿型螺旋紧凑型微带谐振单元(SCMRC)设计了微带大鼠-支路混合耦合器。所提出的结构可以实现尺寸的显著减小和谐波抑制。由于SCMRC完全由微带线构成,因此耦合器很容易使用传统的印刷电路板制造工艺制造。提出的大鼠赛跑耦合器的面积仅为传统情况下的30%,而带有补偿SCMRC的分支线耦合器的面积为传统情况下的24%。另一方面,所提出的耦合器的性能与相应的传统结构和深谐波抑制一样好。采用基于ADS动量的全波分析方法进行了设计和仿真

Miniaturization and harmonic suppression of branch-line and rat-race hybrid coupler using compensated spiral compact microstrip resonant cell
In this paper, a compensated spiral compact microstrip resonant cell (SCMRC) is applied to design a miniaturized microstrip rat-race and branch-line hybrid coupler. The proposed structures can achieve both a significant reduction of size and harmonic suppression. As the SCMRC are constructed entirely from microstrip lines, the couplers are easily fabricated using conventional printed-circuit board fabrication process. The proposed rat-race coupler occupies only 30% of conventional one's area, while the area of the branch-line coupler with the compensated SCMRC is 24% of the conventional case. On the other hand, the performance of the proposed couplers is as good as that of the corresponding conventional structures and deep harmonic suppression in addition. The design and simulation have been performed using full-wave analysis based on ADS Momentum
