“…However, the limited bandwidth of transition, which is due to the enormous impedance difference between the rectangular waveguide and the transmission line is one of the biggest problems faced now [3]- [5]. In recent years, some new ideas about waveguide to microstrip transition are reported, but as another kind of important transmission line, the report of waveguide to strip line transition can be rarely seen.…”

In this paper, a novel waveguide to strip line transition based on LTCC(Low Temperature Co-fired Ceramic) technology at Ka-band is presented. To improve the bandwidth and impedance matching, two major improvements are done, which includes the multilayer step-shape matching structure buried beneath the probe and the gradual-change structure used on substrate layers. According to the simulated results of HFSS, the return loss is better than I5dB and the insertion loss is less than O.3dB, over the specified frequency range from 33.3GHz to 37.4GHz. The simulated size of the transition is compact(S.4mmX Smm X O.94mm).

“…In this paper, a wideband [8] waveguide-to-suspended microstrip line transition [9][10] using an improved antipodal finline has been presented to achieve low return loss and low insertion loss property. In order to implement these transformations, an improved tapered antipodal finline structure is used, as shown in Figure 2.…”

A wideband waveguide-to-suspended microstrip line transition using an improved antipodal finline for energy transferring, is presented. To improve the bandwidth and impedance matching, tapered structure is employed. The transition achieves over the specified 180GHz~230GHz wideband range, with its return loss better than 20dB and insertion loss less than 0.2dB, which can be widely used in the circuits of suspended microstrip line at the low frequency end of terahertz.
