Resume In this article, we proposed a band pass filter; the proposed filter is mainly based on a half mode substrate integrated waveguide (HMSIW). The proposed filter operates in S band with a measured transmitted bandwidth of 1.1 GHz. The proposed structure has dimensions, of 48.5 mm × 16 mm with a measured insertion loss of -1.2 dB. The upper stopband rejection range from 4 GHz to 8 GHz with an attenuation below -15 dB. The filter operates in a transmission bandwidth of [2.9 GHz - 4 GHz] with a fractional bandwidth (FBW) of 27.5 %. A good agreement is reported between the measured and simulated results.

“…Half-mode SIW (HMSIW) and Folded half-mode SIW (FHMSIW) designs have significantly reduced the physical footprint of various RF components while maintaining excellent performance. They are widely used in power dividers, filters, and antennas, utilizing complex techniques like quartermode, half-mode, and folding SIW cavities [5,[6][7][8][9][10][11][12][13]. Further, it is especially significant to trace the progress of fixed/tunable filters.…”

This manuscript introduces an innovative customizable dual pole bandpass filter using a substrate-integrated waveguide technology on a conventional Rogers RT/Duroid 5880 high-frequency laminate. This structure is bifurcated into two identical cavity resonators to get the band stop-band pass-band stop behavior. The structure comprises lumped capacitors to indicate each resonator's operating frequency. Additionally, altering the capacitors in the proposed design facilitates the generation of the tunable dual pole in passband frequency, adding to its versatility. Further, measured and simulated results indicate that the design attains large tuning bandwidth, excellent insertion loss (better than 0.4 dB) and return loss (> 22 dB), high Q-factor (11.8 to 16.87) with fractional bandwidth of 4.8% to 8.9% throughout the tuning range, affirming its practicality and functionality in X-band. A total of 12.3% of tunability is achieved from the structure.

Microwave planar bandpass filters are indispensable in wireless communication systems in most applications. With miniaturization and limited spectrum, there is a great need for a compact, selective bandpass filter with a wide stopband performance. Substrate integrated waveguide (SIW) has become a potential technology for designing and developing microwave and millimeter-wave components, circuits, and systems. This chapter presents novel, compact metamaterial-based bandpass filters with improved stopbands. Several filters’ design methodology and performance are evaluated using broadside-coupled complementary split-ring resonators (BC-CSRR) and edge-coupled complementary split-ring resonators (EC-CSRR) techniques. A comprehensive method to evaluate negative permittivity and permeability for designing the proposed metamaterial structure is also described. These filters have not only compact size but also a wider upper stopband resulting from bandstop resonator characteristics.
