Miniaturized Multilayer Dual-Mode Substrate Integrated Waveguide Filter With Multiple Transmission Zeros

Abstract

Abstract-A compact multilayer substrate integrated waveguide (SIW) dual-mode filter with multiple transmission zeros for highselectivity application is presented. By introducing mixed coupling between source and load, the proposed filter could have four transmission zeros which can be controlled flexibly. Owing to the multilayer structure, the proposed filter occupies similar area in comparison with conventional dual-cavity dual mode SIW filters, but exhibits better frequency selectivity. An experimental filter with a center frequency of 10 GHz is designed using low temperature co-fired ceramic (LTCC) technology to validate the proposed structure, and measured results agree well with simulated ones.

Multi-Mode Substrate Integrated Waveguide Wideband Filter Design With Wide Stopband Rejection Using Complementary Split Ring Resonators and Defected Ground Structures

“…Recently, substrate integrated waveguide (SIW) multiple mode resonators were investigated as an important technique to design RF/microwave filters, due to their numerous advantages such as size compaction, flexible response, high selectivity, high Q-factor, low cost, and easy integration with planar circuits. The most suggested multi-mode resonators in SIW technology are the dual and triple modes resonators [1][2][3][4]. However, their narrow passband prevents their use in the modern communication system as 5G.…”
