“…However, the thing that makes SIW different from other microstrips is the presence of the two rows of metal cylinders, causing low-frequency signals to not propagate in the SIW [7]. Also, a wide operating bandwidth can be achieved using the SIW, as reported in [8]- [9]. In [8], a hybrid and periodically drilled SIW (PDSIW) structure are proposed.…”

Short range radar (SRR) uses the K-band frequency range in its application. The radar requires high-resolution, so the applied frequency is 1 GHz wide. The filter is one of the devices used to ensure only a predetermined frequency is received by the radar system. This device must have a wide operating bandwidth to meet the specification of the radar. In this paper, a band pass filter (BPF) is proposed. It is designed and fabricated on RO4003C substrate using the substrate integrated waveguide (SIW) technique, results in a wide bandwidth at the K-band frequency that centered at 24 GHz. Besides the bandwidth analysis, the analysis of the insertion loss, the return loss, and the dimension are also reported. The simulated results of the bandpass filter are: VSWR of 1.0308, a return loss of -36.9344 dB, and an insertion loss of -0.6695 dB. The measurement results show that the design obtains a VSWR of 2.067, a return loss of -8.136 dB, and an insertion loss of -4.316 dB. While, it is obtained that the bandwidth is reduced by about 50% compared with the simulation. The result differences between simulation and measurement are mainly due to the imperfect fabrication process.

“…Among the proposed spoof SPP waveguides, various groove or pillar structures providing high field confinement have been proposed [18][19][20][21][22] and demonstrated by near field detection techniques in THz regime [23,24]. Meanwhile, different spoof SPP functional devices such as amplifiers, wavelength filters, and sharp bends, have also been reported [25][26][27][28][29][30]. Nevertheless, it is still a great challenge to design and realize compact, low bending loss and high-precision THz integrated circuits, and this is further complicated by the fact that any practical integrated system may have curved connecting sections.…”

Strongly confined surface waves can be achieved on periodically structured metal surfaces and are known as spoof surface plasmon polaritons (SPPs). In this work, several terahertz SPP devices based on curved waveguides are demonstrated. The transmittance and bending loss of 90-degree curved spoof SPP waveguides with a radius of curvature ranging from 200 to 2300 µm are investigated to identify the regime for high transmission. A commutator is designed and experimentally demonstrated. Furthermore, coupling equations are derived and verified for efficient coupling between bend-straight waveguides and between bend-bend waveguides. The results will be of great value for future integrated terahertz plasmonic systems.

“…Meanwhile, it can also possess dispersion characteristic with certain cut-off frequency similarly to the natural surface plasmon polariton, which will benefit the frequency band tailoring with a wide stopband. Therefore, various types of SSPP structures and functional devices in microwave components have been developed [3]- [14] including filters [4]- [7], antennas [9]- [11], splitters [12]- [13] and so on. Among these studies, the symmetrically monometallic SSPP structures could support the odd-mode EM wave with equal-amplitude and reversephase signal [14].…”

In this paper, a filtering balun is proposed based on spoof surface plasmon polariton (SSPP) structure which composes of symmetric H-shaped periodic metallic strip, two types of microstrip-slotline cross-coupling structures and the transition structure between them. The SSPP structure is applied to support odd mode propagation with 180º phase difference and equal magnitude along both sides of the symmetric line, which could transmit the differential signal required for a microwave balun. And then, a new approach for effectively stimulating the odd mode of symmetric H-shaped SSPP structure based on waveguided slotline with a gradient transition structure is proposed and analyzed in detail. In addition, the dispersion characteristic of SSPP can intrinsically bring filtering feature with wide stopband in the balun design. Meanwhile, the two forms of microstrip-slotline cross-coupling structures can not only feed guided wave and realize a pair of balanced ports, but also improve the out-of-band rejection below the objective filtering band. For demonstration, a prototype filtering balun with operating frequency around at 2 GHz is designed, fabricated, and measured. The measured results agree well with the simulated ones which validate the proposed design method and reveal certain advantages of low insertion loss, good amplitude balance and out-of-phase performance as well as the wide stopband.
