A broadband coplanar-to-rectangular waveguide transition using contactless electromagnetic bandgap (EBG) structure in the form of interdigital-pin bed of nails has been introduced in this paper. The electromagnetic (EM) wave propagates from the CPW, and then radiates from the probe into the WR4. The rectangular patch is adopted as the probe to accomplish a broadband performance without an impedance transformer. At the same time, CPW to rectangular waveguide (RW) directly transition without EBG unit also has been designed and the simulated results show the transmission performance has low tolerance to air gap. The interdigital-pin EBG structure is added to the machining splitter of the RW which is no need for strict electrical contact and is not harmful for transition performance. The greatest advantage of the interdigital-pin lattice has a significant pin gap increase and is easy to fabricate for millimeterwave (mm-Wave) and terahertz (THz) applications. The back-to-back prototype is designed, fabricated and measured. The measured jS 11 j is better than À10 dB over 170-260 GHz, covering a bandwidth of 41.8%.

“…With the ever increasing demand worldwide for high-speed data transmissions among mobile terminals, the components involved in the wireless communication links such as antennas, amplifiers, power dividers, transmission lines, and transitions have been under intensive study during the past decades [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. In order to achieve larger bandwidths within a limited spectrum, these components are pushed to operate at higher frequencies which already reach the ranges of millimeter-wave and terahertz (THz) frequencies.…”

“…Though most of the split-ring resonators reported in the literature are designed for narrow band operation at specific frequencies [28][29][30][31][32][33], some studies still show the potential of designing wideband split-ring resonators for high-speed data transmissions. According to [15], the designed split-ring resonator based on a rectangular ring structure achieves a fractional bandwidth of 36% centered at 140 GHz and it is implemented as a wideband transition between rectangular waveguide and coplanar waveguide (CPW). In [34], the split-ring resonators are placed on top of a dipole antenna for gain enhancement at Ka band, while the bandwidth of the dipole antenna is maintained.…”

This paper presents wideband split-ring antenna arrays based on substrate integrated waveguide (SIW) for Ka-band (26.5–40 GHz) applications. The antenna array is fed by a 2.92 mm coaxial connector (K-connector) and the power is equally distributed to each split-ring resonator. The designed coplanar waveguide (CPW), SIW, CPW-to-SIW transition, coaxial-to-CPW transition, and two-stage SIW power divider are described in detail. By using a thin Rogers 6002 substrate with silver epoxy-filled vias, a transition prototype is designed, fabricated, and tested in a back-to-back configuration. A wideband split-ring resonator is developed as a single element and four possible arrangements of antenna arrays are introduced. By combining the designed components and routing paths, two full layouts of the antenna arrays with four split-ring resonators are addressed. As a demonstrator, a 2×2 antenna array prototype in a compact format is designed, fabricated, and tested. The fabricated antenna array achieves a measured directivity of 15.0 dBi with a fractional bandwidth of 23.0% centered at 30.5 GHz.

“…As is reported in [6], a wire bonding was implemented into a rectangular waveguide-to-CPW transition at D-band which achieves similar performances as the E-plane probe while the packaging approaches are more versatile. Besides, by placing a wideband planar antenna at the end of the rectangular waveguide in the direction of maximum radiation, the electromagnetic waves can be guided to the connected CPW [8], [9]. However, in this case the bandwidth of the transition is normally determined by the antenna.…”

This paper presents a rectangular waveguideto-coplanar waveguide (CPW) transition using metal ridge at D-band (110-170 GHz). The proposed transition is useful in particular for packaging circuits with large dimensions. A CPW with extended ground traces is designed on a quartz substrate and its performance is compared with a conventional CPW. Besides, an absorber layer is added underneath for restricting parasitic modes. As the critical part of the transition, the metal ridge is described in detail. The proposed rectangular waveguideto-CPW transition using metal ridge is designed, fabricated, and measured in a back-to-back configuration. The electric field distribution as well as the assembly of the proposed transition is illustrated. For the fabricated transition prototype in a back-toback configuration, the measured return loss remains better than 12.5 dB at D-band which corresponds to a bandwidth of 60 GHz. From 122.5 GHz to 156.5 GHz, the measured insertion loss is less than 3 dB while it increases to 4 dB at the maximum. Thus, each fabricated transition contributes less than 2 dB insertion loss at D-band.
