基于SICL的双极化低剖面毫米波缝隙天线阵列OA
Dual-polarized low-profile mmWave slot antenna array using Substrate-Integrated Coaxial Line
为实现低剖面的双极化边射,设计了一款基于基片集成同轴线(SICL)馈电的1×8双极化低剖面缝隙天线阵列.不同于传统的双极化天线阵列的双套馈电网络垂直堆叠放置,所提出的天线单元与馈电网络位于同层,能够极大降低天线的剖面.结果表明,提出的天线阵列在25.8～27.4 GHz的频带范围内实现了-10 dB的阻抗带宽和大于20 dB的高隔离度.该方法具有馈电网络简单、剖面低、制造成本低等优点,在未来的大规模双极化高增益毫米波应用中具有广阔的应用前景.
To realize low-profile dual-polarized broadside radiation,a 1×8 dual-polarized low-profile slot antenna array fed by Substrate-Integrated Coaxial Line(SICL)is proposed.Unlike conventional dual-polarized arrays in which two independent feeding networks are vertically stacked,the radiating elements and the feeding network of the proposed design are arranged in the same layer,drastically reducing the overall profile.Measured results show that the array achieves a-10 dB impedance bandwidth in 25.8～27.4 GHz and an isolation higher than 20 dB.Benefiting from its simple feeding topology,low profile,and low fabrication cost,the proposed approach is highly attractive for future large-scale,high-gain,dual-polarized millimeter-wave applications.
