“…Since the planar circuit of the SSL is suspended between two ground planes, a much higher portion of the electromagnetic field of the SSL is exposed to air, which results in reduced dielectric loss. Thanks to this property, the SSL has been adopted to realize various types of microwave circuits [1,2,3], such as mixers, frequency multipliers, filters, and so on. On the other hand, the metallic waveguide still plays an essential role in microwave circuits and systems for its high power-handling capacity and high-Q property.…”

A full Ka-band in-line suspended stripline (SSL) to rectangular waveguide transition is proposed in this paper. The antisymmetric probes are introduced to transform the quasi-TEM mode of the SSL to the TE10 mode of the rectangular waveguide. Two slots with polygonal shapes are cut on the two probes respectively to improve the bandwidth of the transition. To verify this design, a back-to-back structure is fabricated and tested. The experimental results show that the insertion loss of better than 0.32 dB and the return loss of more than 14.2 dB are obtained from 25 to 40 GHz. The measurement results agree well with the simulations.

“…Similar to SSS structure, a filter with a coaxial tube housing the suspended resonators was reported in [7]. Menzel et al [8][9][10][11] used a quasi-lumped approach to design some SSS filters and diplexers. In their works, coupled SSS resonators of various shapes were adopted in filter design.…”

Abstract-This paper presents the design of two suspended substrate stripline (SSS) bandpass filters (BPFs), both with a source-load coupling structure embedded to create a transmission zero (TZ) near each side of the passband edges. For the first BPF, the physical circuit layout is proposed first and followed by the establishment of an equivalent LC circuit. The optimization of element values of the LC circuit using a circuit-level simulator leads to quick adjustment of the structural parameters of the physical circuit layout with the aid of a full-wave simulator. For the second BPF, the ingenious equivalent LC circuit modified from that of the first one is proposed for bandwidth enhancement, which is achieved by exciting two extra loaded resonances in the passband. With the element values of the LC circuit optimized, proper reshaping the physical circuit layout from that of the first BPF is easily accomplished. The presented lumped and full-wave mixed approach is very efficient in that the circuitlevel simulator is used to the largest extent and the time-consuming full-wave simulator is employed only at the later stage of the design. Experiments are conducted to verify the design of the two SSS BPFs and agreements are observed between the measured and simulated data.

“…This results in low insertion loss in the passband. Suspended stripline bandpass filters, comprising capacitively coupled quasi-lumped resonators on both substrate sides, have a small size and wide upper stopband [1][2][3]. A dual-mode version of such broadband filters is described in [4].…”

Abstract-Miniature bandpass filter constructions based on a novel dual-mode suspended stripline resonator are proposed. Because of a special structure of the resonator, the frequencies of two first oscillation modes may be brought closer together. That allows realizing narrowband filters with the wide upper stopband. The filters have low insertion loss in the passband at small dimensions. Several transmission zeros substantially improve the filter performance. The derived coupling coefficients account for some features in the frequency response of the filter. The second-order and fourth-order filters with transmission zeros have been fabricated and measured.
