A broadband differential-line-to-waveguide transition covering the 260-300 GHz band was developed in this study. This transition consists of a differential line inserted from the narrow wall of the waveguide that excites an X-shaped patch located at the waveguide center. As the two corners of the patch are excited electromagnetically via differential signal lines in the opposite phase, orthogonal current components that radiate the TE 10 mode into the waveguide are generated. Broadband operation is achieved via the double resonance of the X-shaped patch and a cavity formed by the via-hole arrangement with apertures patterned in a multi-layer substrate. The transition geometries are optimized via electromagnetic simulation using a finite element method. Transition performance is evaluated through measurements and simulations.

A novel transition between rectangular waveguide (RWG) and balanced transmission line with magnetic closed loops has been developed. A conventional RWG directly mounts on a printed circuit board that actualizes energy transition. Using a pair of centrosymmetric magnetic closed loop, the TE10 mode converts to TEM mode, and balanced ports are obtained. Based on the structural characteristics investigation, the transition is fabricated and measured. The center frequency of the operation is 32.5 GHz, and the bandwidth is wider than 27% for insertion loss no more than 0.6 dB and return loss more than 15 dB. Between the two balanced ports, the magnitude imbalance is less than 0.4 dB, and the phase difference is less than 3°. Integration within the balanced ports makes the transition a promising candidate for miniaturized system in antenna.

“…Another potential application of the transition is the testing of PCB-based millimeter-wave passive circuits, circuits, such as antennas, filters, and power dividers. In the open literature, various WG-microstrip line (MSL) transitions have been reported [2][3][4][5][6]. In [2], a vertical WGdifferential MSL (DMSL) transition was reported, in which bandwidth was enhanced using a short-end parasitic patch.…”

“…In [2], a vertical WGdifferential MSL (DMSL) transition was reported, in which bandwidth was enhanced using a short-end parasitic patch. In [3], Chebyshev-based vertical impedance transformers were designed in the WG section and connected to a DMSL, which does not require a backside cavity, as in [2]. In [4], a wide-band transition was designed by combining an E-plane probe and an MSL transition that covered the whole W-band.…”

In this work, a design of a transition from a standard D-band waveguide to substrate integrated waveguide (SIW) technology is presented for 6G applications. The waveguide is connected to an SIW by carving a slot at the bottom metal of the printed circuit board (PCB). A pair of vias is added to shift the inband null to a higher frequency, whereas a parasitic patch is used to improve impedance matching. A prototype of a back-to-back SIW transition is fabricated and measured using D-band VNA extenders. The measurement shows a −10 dB impedance bandwidth of 26.5 GHz (135–161.5 GHz) and a 3 dB bandwidth of 28 GHz (133.8–161.8 GHz). The transition can be integrated with a D-band antenna for 6G applications.
