Conference Paper

A. Gopinath and P. Lal, R., “Substrate Integrated Waveguide Based Hybrid Cavity Filter For Ku Band Applications”, in 6th International Conference on Communication and Signal Processing 2017, A Adhiparasakthi Engineering College, Chennai, India, 2018.[Abstract]


In this paper a hybrid cavity substrate integrated waveguide filter is proposed and demonstrated for Ku band application. Hybrid cavity which is the combination of both circular and rectangular cavity, showcases a better frequency selectivity and Quality Factor in comparison with other cavity based substrate integrated waveguide filters. Quality Factor requirements are met by the introduction of shorting posts at specified points inside the cavity. Filter operates at a frequency of 13GHz with an optimized Q factor of 377.096. The detailed analysis of the proposed structure is simulated and studied using the ANSYS HFSS software.

In this paper an effective crossover is designed using Substrate Integrated Waveguide (SIW) technology. Reflection, transmission and isolation of the crossover is studied along with the electric field to substantiate the effectiveness of the crossover. At the operating frequency, an isolation better than 35 dB is achieved between the decoupled ports with a transmission of *1 dB through the coupled ports. © Springer India 2016.
