团队有关一种具有相位响应重构能力的毫米波宽带高效单层反射阵列天线成果在INT J RF MICROW C E期刊上发表

论文名称为Millimeter-wave wide-band high-efficiency single-layer reflectarray antenna with ability of phase-response restructuration”。本文提出了一种具有相位响应优化能力的毫米波宽带高效率单层反射阵天线。在亚波长技术的基础上,采用外环固定尺寸的三环变尺寸单元可以提高单元的仿真准确性,同时可以抑制单元间的互耦影响,提高单元的相位补偿精度。采用分区优化方法,对单元的相位响应进行分区优化。优化重构的单元相位响应曲线具有更好的平行性和线性度,改善了单元相位补偿能力的同时,有利于提高天线的工作带宽和口径效率。实验结果表明该设计方法能够有效改善小口径反射阵天线的宽带性能。设计加工的反射阵天线在频率34GHz的最大增益为35.4dBi,口径效率为67.7%1-dB增益带宽为20.3%工作主要完成人刘彦、程钰间、樊勇。

AbstractThis work presents a single-layer millimeter-wave wide-band high-efficiency reflectarray antenna with the subwavelength element based on the partial-optimization method. A three-loop subwavelength element with the unchanged parasitic outer-ring is used to guarantee the design accuracy and depress the dispersion influence. Then, the partition-optimization method is used to restructure the element phase-response characteristic. The proposed design method is beneficial to expand the reflectarray antenna bandwidth and achieve the high efficiency, especially for the large-aperture reflectarray antenna. A center-fed reflectarray antenna is designed and fabricated at the center frequency of 34 GHz. The measured gain of the proposed reflectarray antenna is 35.4 dBi with the 1 dB gain bandwidth of 20.3%, that is, from32.3 GHz to 39.2 GHz. The proposed reflectarray antenna can keep the stable radiation pattern for a multi-band wireless backhaul system.
