摘要

本文提出了一种基于分形透射超表面的X波段小型化宽带高透射率平面透镜天线.单元设计依照天线-滤波-天线的设计思想，满足巴特沃斯响应，实现单元宽带和高透射率特性.利用分形和堆栈结构，进一步扩大天线带宽，同时实现单元小型化.基于上述设计思想，设计了两种同时具有小型化、宽带、高透射率特性的三层透射超表面单元，单元周期仅为4.5 mm（0.15

）.为验证单元特性，设计、仿真、加工、测试了基于两种设计单元的频率选择表面.仿真和测试结果表明，提出的两种频率选择表面带宽分别为40%和64%，与入射角在60°以内条件下的反射系数（

）和透射系数（

）的3 dB带宽对应.此外，为了实现透射相位在满足要求特性的尺寸可变范围内的相位360°覆盖，并进一步提高平面透镜天线效率，本文对第二种超表面结构进行改进，提出了一种基于七层透射超表面单元的平面透镜天线，并给出等效电路模型辅助验证.仿真结果表明，本文提出的平面透镜天线的法向最大增益为12.5 dBi，相比馈源高5.25 dB，且具有20%的相对带宽，口径效率高达78%，证明了该天线具有良好的辐射特性.

Abstract

In this paper

a miniaturized broadband planar lens antenna(PLA) with high transmittance based on fractal transmissive metasurface elements is proposed at the X band. In order to achieve the characteristics of broadband and high transmission

units of PLA are designed based on the concept of antenna-filter-antenna(AFA) which satisfies butterworth response. Fractal geometries and stacked structures are used to expand bandwidth as well as realize miniat

urization. Two kinds of structures are designed combining patches back-to-back and a cross-shaped slot or a double cross-shaped slot etched on the common ground plane. The unit-cell periodicity is just 4.5 mm(0.15

). In order to validate features of units

prototypes of two kinds of frequency selective surfaces(FSSs) which consist of the same proposed units are designed

simulated

manufactured and measured. Presented FSSs possess bandwidths of 40% and 64%

which are corresponding to 3 dB bandwidths for both reﬂection(

) and transmission coeﬃcients(

) at an incident angle within 60°. To satisfy the transmission phase of the unit whose range is from 0° to 360° within the variable size and further enhance the efficiency of the PLA

a seven-layer element based on the improved abovementioned unit is proposed. Equivalent circuits are calculated and simulated to verify the correctness of the structure. A prototype of the proposed PLA is designed and simulated. The simulation results show that the PLA provides a maximum gain of 12.5 dBi

which is 5.25 dB higher than the feeding antenna over a wide bandwidth(20%) and a high aperture efficiency(up to 78%). These show that the PLA has good radiation characteristics.
