研究目的
Investigating the design and performance of dual circularly polarized series-fed arrays based on Sequential rotation technique with uniform radiation elements.
研究成果
The analysis of axial ratio of series-fed SR array with uniform radiation elements and feeding network is presented. The proposed design can realize dual-CP operation. A dual-CP series-fed SR antenna is designed with the guidance of the analysis, providing a simple and effective way to design dual-CP SR series-fed antennas.
研究不足
The operation bandwidth of the array is mainly limited by the frequency sensitivity of the power coupling coefficient α. The current distribution on the array is not uniform, leading to lower antenna aperture utilization and relatively small peak gain.
1：Experimental Design and Method Selection:
The study employs the Sequential rotation (SR) technique for designing dual circularly polarized (CP) series-fed arrays with uniform radiation elements. Theoretical analysis focuses on the relationship between the axial ratio (AR) and four key parameters of the array.
2：Sample Selection and Data Sources:
An eight-element dual-CP SR array working at 10 GHz is designed and measured to demonstrate the theoretical analysis.
3：List of Experimental Equipment and Materials:
The antenna is processed with the substrate of Rogers RO4350B and Rogers RO4450F. The relative permittivity is 3.66 and 3.52, respectively, and both the dielectric loss tangents are 0.
4：0F. The relative permittivity is 66 and 52, respectively, and both the dielectric loss tangents are Experimental Procedures and Operational Workflow:

4. Experimental Procedures and Operational Workflow: The design targets of array port isolations are larger than 15 dB in operation bandwidth. The power coupling coefficient α of the proposed element is mainly determined by LZ_
5：Data Analysis Methods:
The simulated and measured reflection coefficients, isolation, bore-sight axial ratios, gains, and radiation patterns are analyzed to evaluate the performance of the proposed antenna.
