宽带缝隙堆叠贴片微带反射阵天线的研究

内容简介：微带反射阵天线具有易折叠、易携带等特点,结合缝隙堆叠贴片（ASP）微带单元频带较宽的优势,能进一步展宽缝隙耦合反射阵的带宽。通过求解相位计算公式,得到反射阵表面相位分布。给出了ASP微带天线的设计参数、S参数曲线及对应ASP单元的反射相位曲线,用所设计单元组成225元反射阵模型,结果显示该模型中心频率最大增益为26.03dBi,1.5dB增益带宽为33.3%,在整个带宽内具有良好的工作性能。

Abstract：Due to the characteristics of easily folded and portability for the microstrip reflectarray antenna,combined with the advantage of broadband of aperture-stacked patch element, the band of the aperture-coupled reflectarray antenna can be broaded further.Designed parameters of ASP microstrip antenna,S parameter and reflection phase curve of aperture-coupled element are proposed in this paper.A 225 elements reflectarray antenna is designed.The result shows that 26.03dBi maximum gain in center frequency and 33.3% 1.5dB bandwidth of gain are obtained.Further more,it can provided good performance in this case.
