“…The CSRR structure consists of two diamond-shaped split resonant rings with their openings opposite (face to face) to each other for tight coupling between them. As CSRRs are integrated with SIW, a passband with an evanescent resonant mode lower than the SIW's cutoff frequency is created, miniaturizing the size of the conventional SIW [13].…”

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.

“…To avoid the deficiencies mentioned above, a new design structure to implement a quasi-elliptic SIW filter is proposed. Coplanar waveguides (CPW) [17] and complementary split-ring resonators (CSRR) [18][19][20] have been embedded in the SIW cavities to achieve miniaturization, but they result in bad insertion loss. The spoof surface plasmon polariton (SSPP) waveguides that support the surface wave transmission on thin, planar corrugated metals [21,22] have attracted the interest of researchers due to their exceptional properties, such as high confinement [23], low loss [24], potential for solving severe on-chip signal integrity and interference issues [25], as well as the possibility for minimizing the circuit area [26,27].…”

Wideband Substrate Integrated Waveguide Chip Filter Using Spoof Surface Plasmon Polariton

This article presents a novel wideband bandpass filter based on the integration of a substrate integrated waveguide (SIW) and a spoof surface plasmon polariton (SSPP). An SIW cavity with periodic arrays of meander-slot units is etched on the top metallic layer to achieve the characteristics of a multi-order filter with good performance. The passbands can be flexibly selected by varying the geometric parameters of the SIW and SSPP to adjust the lower and upper sidebands independently. Using a redistribution layer (RDL) process, a novel 3D capacitive interconnection called a through-dielectric capacitor (TDC) is proposed and collaboratively designed with an interdigital capacitor to achieve capacitive source-load cross-coupling. The proposed filter has a center frequency of 60 GHz, with a wide 3-dB fractional bandwidth of about 45.8%. The improved simulated sideband suppression has a 30 dB rejection at 40 GHz and 75.4 GHz, corresponding to a 30-dB rectangular coefficient of 1.28.

In this article, a novel left‐handed (LH) waveguide transmission line with good filtering performance is proposed and implemented below the TM mode cutoff frequency. TM11 mode is employed and transmitted inside the waveguide. The LH passband is achieved by TM mode cutoff operation and complementary split‐ring resonator (CSRR) loading, which are able to provide negative μ and ε, respectively. It constitutes the main novelty here with the rectangular waveguide TM mode and CSRR to realize the LH characteristics, which has not been done before. Based on this passband, two bandpass filters with high‐selectivity are designed and fabricated. The measured results are in agreement with the simulated data. It shows a good LH passband below the cut‐off frequency and TM11 mode propagation is also detected at higher frequency above the cutoff.
