研究目的
Investigating the design and implementation of a broadband and fully 3-D printed E-plane coax-to-waveguide transition and a monolithically 3-D printed waveguide magic-T based on the transition.
研究成果
The proposed E-plane waveguide magic-T based on air-filled rectangular-coax-to-waveguide transitions demonstrates good RF performance with broadband and low-loss characteristics. The monolithic prototyping simplifies the fabrication process and reduces device weight, showing potential for enhanced design and fabrication flexibility in microwave applications.
研究不足
The power handling capability is limited by the heat deflection temperature of the building material, and the assembly tolerance can be eliminated but requires precise design and fabrication.
