[IEEE 2019 International Conference on Microwave and Millimeter Wave Technology (ICMMT) - Guangzhou, China (2019.5.19-2019.5.22)] 2019 International Conference on Microwave and Millimeter Wave Technology (ICMMT) - A Novel Power Divider Based on Hybrid Circuit of Surface Plasmon Polaritons and Substrate Integrated Waveguide

摘要： In this paper, a novel power divider based on hybrid circuit of spoof surface plasmon polaritons (SPPs) and substrate integrated waveguide (SIW) is proposed. The hybrid circuit consists of three paths including one input branch (SIW) and two identical output branches (spoof SPPs). The pass-band of the power divider is controllable by designing the geometrical parameters of spoof SPPs and SIW, which is because that spoof SPPs and SIW can adjust the upper and lower cutoff frequencies, respectively. Simulated results demonstrated the characteristics of power dividers, such as highly efficient transmission, low loss, and bandwidth adjustable. The combining of spoof SPPs and SIW provides more potential for the development of the integrated functional devices in microwave frequency.
