## Abstract This article presents an electronically tunable varactorโloaded microstrip bandpass filter based on the planar split ring resonators (SRRs). The varactor is a reverseโbiased semiconductor diode, and is connected between the concentric rings of the SRR. An individual varactor loaded SRR
## Abstract One novel bandpass filter implemented with combination of two different structuresโcomplementary split rings resonators (CSRRs) and substrate integrated waveguide (SIW) is proposed in this article. Several CSRRs are etched on the surface of SIW to form the stopband with very sharp rejec
