High Q Power Divider/Combiner with High Output Isolation using Substrate Integrated Waveguide Technology abstract
A power divider (PD)/ power combiner (PC) with high quality factor and enhanced output ports isolation using substrate integrated waveguide (SIW) technology is proposed. An SIW cavity is designed to provide a high quality factor filtering response and an SMD resistor is attached between two output ports to realize the high isolation. The value of the applied resistor is calculated by using the even and odd mode analysis. The measured results obtained from testable model are in good agreement with the simulated results. These results show that the return loss is 23 dB, the minimum insertion loss is 4.55 dB including intrinsic 3 dB insertion loss of PD, and the isolation between output ports is 20 dB, which shows that the proposed design could be an important component in microwave circuits.
