研究目的
To propose a single-layer substrate-integrated waveguide (SIW) filtering power divider (FPD) with fully differential operation at 28 and 39 GHz for 5G millimeter-wave applications, achieving high in-band common-mode rejection and improved output return loss and isolation in dual bands.
研究成果
The proposed single-layer dual-band balanced SIW FPD is suited to applications in the 5G millimeter-wave differential antenna/array feeding network, demonstrating good all-port matching and in-band isolation.
研究不足
The conductor loss is anticipated to increasingly dominate at millimeter waves, affecting the insertion loss of the FPD.
1：Experimental Design and Method Selection:
The design involves three SIW cavities with differential and common modes properly designed to form three-pole dual passbands. A novel approach to find the proper location of isolation resistors is presented.
2：Sample Selection and Data Sources:
The FPD was fabricated on a Rogers RT/Duroid 5880 substrate.
3：List of Experimental Equipment and Materials:
Rogers RT/Duroid 5880 substrate, 100-Ω SMD resistors.
4：Experimental Procedures and Operational Workflow:
The FPD was characterized for differential-mode input/output return loss, insertion loss, isolation, and common-mode suppression.
5：Data Analysis Methods:
Full-wave extracted quality factors and coupling coefficients were used for synthesis.
