The fabrication process of an advanced transparent cyclic olefin copolymer (COC)-based laminate is introduced, along with the laser cutting technology for circuit pattern. Then, a three-way Gysel divider with an equal power-dividing ratio is reviewed, designed and measured, based on the proposed COCbased laminate. The measured results are compared to those from a similar three-way Gysel divider based on traditional RT/duroid 5880 laminate, from which we can see that COC-based laminate has the advantage of lower loss, with other advantages such as low cost, easy realization, high-precision, and even the transparency. This laminate can be an excellent candidate for a substrate at microwave or millimeterwave circuits.

“…It should also be noted that, in general, construction of the inverse models may be hindered by non-uniqueness issues (e.g., Refs. 71 , 72 ). Notwithstanding, for typical microwave passive components, the operating conditions (e.g., operating frequency, bandwidth, etc.)…”

Simulation-based optimization of geometry parameters is an inherent and important stage of microwave design process. To ensure reliability, the optimization process is normally carried out using full-wave electromagnetic (EM) simulation tools, which entails significant computational overhead. This becomes a serious bottleneck especially if global search is required (e.g., design of miniaturized structures, dimension scaling over broad ranges of operating frequencies, multi-modal problems, etc.). In pursuit of mitigating the high-cost issue, this paper proposes a novel algorithmic approach to rapid EM-driven global optimization of microwave components. Our methodology incorporates a response feature technology and inverse regression metamodels to enable fast identification of the promising parameter space regions, as well as to yield a good quality initial design, which only needs to be tuned using local routines. The presented technique is illustrated using three microstrip circuits optimized under challenging scenarios, and demonstrated to exhibit global search capability while maintaining low computational cost of the optimization process of only about one hundred of EM simulations of the structure at hand on the average. The performance is shown to be superior in terms of efficacy over both local algorithms and nature-inspired global methods.

“…So, GPD has many advantages in comparison to WPD such higher power handling, using at higher frequencies and capable of implementation on nonplanar structures. Microwave/mm-wave GPD has already been implemented based on various guiding structures such as microstrip [2]- [4], rectangular waveguide [5], ridge waveguide [6], etc. Besides, many efforts have been done to improve the basic structure of the GPD such as multi-band operation [7]- [8], with unequal output power ratio [9], etc.…”

The novel ridge-gap waveguide (RGW) technology which uses a full metal structure has many advantages in micro/mm-wave frequencies such as low loss, broad bandwidth, low sensitivity to manufacturing errors, and easy integration with active components, etc. In this paper, a Ku-band Gysel power divider (GPD) is proposed and experimentally demonstrated based on the RGW technology for the first time, to the best of our knowledge. An RGW-to-WR62 transition is also designed and fabricated. The proposed RGW-based GPD with WR62 transitions shows low-loss equal-power division in phase with good impedance matching and isolation in the Ku band. The measured results are in good agreement with the simulations. Besides, it is shown that the proposed structure can be used as a 3-way GPD with an unequal power splitting ratio. The proposed RGW-based GPD can be extended to a 2N-way power divider which can find applications in solid-state power amplifiers, array antenna feed networks, etc.INDEX TERMS Gysel power divider (GPD), ridge gap waveguide (RGW), Ku-band, return loss, insertion loss.
