研究目的
To design a novel 180? out-of-phase power divider based on stepped-impedance slotline with improved isolation between output ports.
研究成果
The proposed out-of-phase slotline power divider based on stepped-impedance slotline exhibits good return loss at all ports, high isolation, excellent phase balance, and flat group delay over the 5 GHz–10 GHz range.
研究不足
The design sacrifices some properties to improve isolation and return loss at output ports, and the lumped resistor may introduce insertion loss.
1：Experimental Design and Method Selection:
The design employs a T-junction formed by microstrip line and slotline for out-of-phase power dividing, with stepped-impedance slotline and a lumped resistor to improve isolation.
2：Sample Selection and Data Sources:
The power divider is fabricated on Rogers 4350B substrate.
3：List of Experimental Equipment and Materials:
Rogers 4350B substrate, lumped resistor.
4：Experimental Procedures and Operational Workflow:
The power divider is designed with specific dimensions and tested for performance metrics like insertion loss, return losses, isolation, phase balance, and group delay.
5：Data Analysis Methods:
Simulated and measured results are compared to validate the design.
