“…However, the EM field is going through microstrip-coax-microstrip modes transition, which inevitably increases loss especially at mm-Wave frequencies. The other microstrip transitions reported has bandpass frequency response [3][4][5] and not allowing DC though. When they are used in a complicate RF front-end system, circuit design flexibility is restricted due to the bandwidth issue.…”

In this paper, a novel millimeter-wave microstrip-tomicrostrip transition is demonstrated for electrically thick substrate (t>λ/4). The design maintains the same EM mode throughout the transition area, thus obtaining excellent matching and loss performance. Simulated result shows that the proposed design performs well up to 40GHz for microstrip lines on a 100mils multilayer PCB with less than 1.5dB loss. This design is compatible with conventional PCB fabrication, thus no additional cost is added.

“…Vertical transitions can achieve the signal interconnection between multilayer structures. Usually, vertical transition can be achieved in 3 ways such as via‐connection vertical transitions, cavity‐coupled vertical transitions, , and aperture‐ or slot‐coupled vertical transitions , wherein the aperture‐ or slot‐coupled vertical transitions gain more attention because of easy fabrication and low cost. However, the reported microstrip vertical transitions are all single‐ended, and no balanced microstrip‐to‐microstrip vertical transition has been reported.…”

A wideband balanced microstrip‐to‐microstrip vertical transition is proposed. This vertical transition is based on the back‐to‐back hexagonal microstrip lines with a slot on the common ground. The etched slot is used to achieve the vertical transmission of differential‐mode signal and the suppression of common‐mode (CM) signal. The back‐to‐back hexagonal microstrip lines enable the transition to obtain wide bandwidth. One prototype shows the fractional bandwidth (|Sdd11| ≤ −15 dB) of 63%, the minimum (maximum) insertion loss of 0.7 dB (1.9 dB), and the minimum CM suppression inside passband of 27 dB.

“…Very recently, an ultra-wideband microstrip-to-micorstrip vertical transition is presented in [16], as illustrated in Fig. 1(b), by installing a pair of stubs in the top-and bottom-layer microstrip feeding lines in proximity to the slotline section.…”

“…1(a), this transition with symmetrical feeding architecture only employed the first resonant mode in the slotline resonator, and its two additional resonant poles are created by the strip conductors across the slotline. However, no clear description has been given in [16] on the rationale of a three-pole wide operating band and design procedure for prescribed performance.…”

A class of wideband microstrip-to-microstrip vertical transitions is proposed via multiresonant modes in a slotline resonator formed on their common ground plane. The slot acts as a multimode resonator with microstrip lines at its two sides as the input and output terminals. Multiresonant modes in this slotline resonator can be properly excited by setting a certain offset distance at two feeding points. As such, good signal transmission between the top-and bottom-layer microstrip lines can be achieved over a wide frequency range determined by these resonant modes. In this context, the initial transmission line models of these transitions are further deduced. Then, their simplified generalized highpass topologies are synthesized to design these transitions with prescribed operating bandwidths and ripple levels. Finally, by calculating the turn ratios of those involved transformers in the initial transmission line models of these transitions, the synthesized models are constructively mapped into all the physical dimensions to allow one to carry out an efficient design of these transitions. As examples, two vertical transitions are designed, fabricated and tested to verify the predicted frequency responses. The synthesized, simulated, and measured results are found in good agreement with each other.Index Terms-Equivalent circuit, multimode slotline resonator, offset feed, synthesis design, wideband vertical transition. he is currently an Associate Professor.
