摘要

本文报道了一种用于S波段和C波段应用的单波段单极天线,它被转换为三频天线。这种变换是在两个不同的混合SRR单元的帮助下完成的,这两个单元嵌入在天线的截断接地平面上。这些混合SRR单元是通过将方形开口环和圆形开口环组合成两种不同的配置来创建的。模拟结果与测量结果一致,并提供分析以评估设计的有效性。该分析可用于估计超材料晶胞在生成多个频带方面的有用性。测量的工作频带分别为2.72-2.83GHz、3.54-4.35 GHz和4.72-5 GHz。这些频段正在许多国家用于5G通信的中频频段。所开发的天线被小型化为0.19λ0×0.25λ0(λ0是2.72 GHz的自由空间波长)。在单一设计中实现了两个目标,即小型化和多条带。在有缺陷的接地平面引入不同的混合SRR单元引起多频带,并且单元在较低频率下的谐振导致天线的有效电长度的增加而不增加其物理尺寸。文中还验证了晶胞的超材料特性。

Performance Evaluation of Triple band Microstrip Antenna using Hybrid SRRs on Fractal Ground Plane
A single-band monopole antenna, transformed into a triple-band antenna for S-band and C-band applications is reported in this paper. This transformation is done with the help of two different hybrid SRR unit cells, which are embedded on the truncated ground plane of the antenna. These hybrid SRR unit cells are created by combining square split ring and circular split ring into two different configurations. Simulated results are in coherence with the measured results and analysis is provided to evaluate the efficacy of the design. This analysis can be used to estimate the usefulness of metamaterial unit cells in generating multiple frequency bands. The operating frequency bands measured are 2.72-2.83GHz, 3.54-4.35 GHz, and 4.72-5 GHz respectively. These bands are being used in the mid-band frequency range of 5G communication in many countries. The developed antenna is miniaturized to the size of 0.19λ0 ×0.25λ0 (λ0 is the free space wavelength at 2.72 GHz). Two objectives i.e., miniaturization and multi-banding are fulfilled in a single design. The introduction of different hybrid SRR unit cells at defective ground plane causes multi-banding and resonance of a unit cell at a lower frequency leads to an increase in the effective electrical length of the antenna without increasing its physical size. The metamaterial characteristic of the unit cells is also verified in the article.
