Design of a planar Transversal Signal Interference-Based Bandstop Filters for Millimeter-Wave Applications

Abstract

In this research, we demonstrate the realization of a compact millimeter-wave bandstop filter (BSF) by employing Microstrip technologies The arrangement is based on the concept of transversal signal interference, which is accomplished by connecting two transmission lines in parallel with defined characteristic impedances and electrical lengths. This design allows for sharp rejection of unwanted signals without the need for additional resonators. The designed filter utilizes a ROGERS RT/Duroid 6002 substrate with specific properties, including a thickness of 0.252 mm, a dielectric permittivity constant of 2.94, and a loss tangent of 0.0012. To ensure its effectiveness, the filter undergoes optimization and validation using two electromagnetic solvers: ADS, and CST-MWS.
