“…In [8], a bandpass filter using an optimized coupling matrix synthesis method is designed, which was large. In [9], a bandpass filter based on half mode substrate integrated waveguide, periodic CSRRs, and defected ground structures is proposed, but is large. In [10], a low-profile metamaterial bandpass filter loaded with a four-turn complementary spiral resonator for wireless power transfer applications is designed.…”

In this paper, Compact bandpass filters have been designed. A single bandpass filter was designed using novel triple concentric complementary split-ring resonators placed along the microstrip line in the ground plane. Gaps and via were placed on the microstrip line to control electromagnetic characteristics, resulting in a single bandpass filter. In turn, spiral resonators were attached to the microstrip transmission line at the gaps in the transmission line to obtain a compact dual passband filter. Stepped impedance microstrip line and Tshaped stubs were attached to the microstrip line in between spiral resonators. The structure designed resulted in a Triple bandpass filter. A fractional bandwidth of 3% was achieved at the center frequency of 3GHz. The filter had a 1.5dB insertion loss which is the minimum value in the operating frequency band. The filter resonance frequency was 1.32 GHz and 2.47GHz which have a fractional bandwidth of 7.5% and 4.85% respectively and the corresponding insertion loss was 1.3dB and 1.8dB respectively. The triple bandpass filter had a fractional bandwidth of 1. 16%, 11.4%, and 1.86%, centered at 1.29 GHz, 2.27 GHz, and 3.21GHz with 1.6dB, 1.3dB, and 1.8 dB insertion loss at the respective frequencies. The proposed bandpass filters are useful for GPS, WLAN, WiMAX, and radar applications.

“…This defected ground plane disturbs the flow of the surface current, and this disorder of the current alters the characteristics of the structure [8]. The HMSIW technique is used to reduce the SIW structure size, keep it with the same performance, and it was widely used in many implementations [9]. In the literature [11][12][13][14], many bandpass filters were proposed to overcome the above-mentioned problems.…”

A miniaturized half-mode substrate-integrated-waveguide (HMSIW) based bandpass filter with defected ground surface (DGS) for sub-5G applications is presented in this research. The novelty in this article is the proposal of an original configuration of a SIW Filter composed of a mix of DGS cells; each couple of C shapes is etched exactly beneath of two cross shapes, which give us long rejection. We have used six periodic cross-shaped slots as DGS in top of the cavity plane for disturbing the current and creating stopband rejection, and we have also used three couples of C-shaped DGS cells in the bottom plane to improve the performances of the proposed filter. This novel bandpass filter is developed on a 1.54 mm-thick FR-4 (with relative permittivity of 4.3 and tangent loss of 0.025) operating in the band ranging from 3.4 GHz to 3.8 GHz with a bandwidth of 400 MHz and having the size of 13.5 × 38.6 mm 2 . The proposed HMSIW-based filter is simulated, fabricated, and measured. The measurement results are in decent agreement with the simulation results.

“…The advantage of using a Hilbert curve as a resonator is that we can get diverse responses simply by varying line-to-spacing ratio and the orientation of the curve [8,9]. To improve the performance of components, Many papers have treated the combination between SIW and DGS [10,11]. To ensure a good adaptation between SIW and planar circuits, several types of transitions have been proposed for this purpose.…”

In this article, two compact Substrate Integrated Waveguide (SIW) bandpass filters based on Defected Ground Structure (DGS) technology are proposed. Hilbert Cell of second order is the resonator shape proposed for the DGS of both filters, where the first filter DGS consists of five pairs, and the second one uses only three pairs. The pair used in the first filter consists of two cells located side to side whereas they are placed face to face in the second filter. In order to enhance the performance of the second filter and based on the evanescent-mode technique, three other pairs of first order Hilbert cells are engraved on the top layer. Both bandpass filters are designed to operate in C band with a measured bandwidth of 1.8 GHz for the first filter and 0.86 GHz for the second one. The proposed structures have the same physical dimensions, which is 38.1 mm × 16 mm with different measured insertion losses of −2.5 dB and −2.7 dB. Both structures exhibit an upper stopband rejection with attenuation around −20 dB and −29 dB, respectively. The filters operate in a transmission bandwidth of 3 GHz] and [5.27 GHz-6.13 GHz] with a fractional bandwidth (FBW) of 28.1% and 15.09% for the first filter and the second filter, respectively. A good agreement is reported between the measured and simulated results.
