This paper presents results of a study on a bandpass and bandstop waveguide filter design using printed-circuit discontinuities, representing resonating elements. These inserts may be implemented using relatively simple types of resonators, and the amplitude response may be controlled by tuning the parameters of the resonators. The proper layout of the resonators on the insert may lead to a single or multiple resonant frequencies, using single resonating insert. The inserts may be placed in the E-plane or the H-plane of the standard rectangular waveguide. Various solutions using quarter-wave resonators and splitring resonators for bandstop filters, and complementary split-ring resonators for bandpass filters are proposed, including multi-band filters and compact filters. They are designed to operate in the X-frequency band and standard rectangular waveguide (WR-90) is used. Besides three dimensional electromagnetic models and equivalent microwave circuits, experimental results are also provided to verify proposed design. Another aspect of the research represents a study of imperfections demonstrated on a bandpass waveguide filter. Fabrication side effects and implementation imperfections are analyzed in details, providing relevant results regarding the most critical parameters affecting filter performance. The analysis is primarily based on software simulations, to shorten and improve design procedure. However, measurement results represent additional contribution to validate the approach and confirm conclusions regarding crucial phenomena affecting filter response.

This paper presents a Complementary Loaded Split Ring Resonator (CLSRR) based compact, wideband, waveguide bandpass filter. Three identical CLSRRs were fabricated and placed on the transverse plane of a standard WR-90 waveguide at a quarter wavelength distance to form the filter. The proposed filter was initially simulated using Ansoft HFSS (version 14) and then fabricated and measured. The measured result shows a fractional bandwidth of 18.80% at 10.05 GHz. Total length of the filter is only 20.33 mm which is compact enough. Detailed design procedure has been presented along with the equivalent circuit of the filter. A table has been provided to compare the performance of the proposed filter with those already available in the literatures. The table shows that the proposed filter is compact and has higher bandwidth, lower insertion loss and higher return loss.
