摘要
基于等效电路模型理论,在介质基板单侧放置了两个交错多开口的矩形金属环,形成了一个新的材料结构,通过理论分析和模拟仿真,提取了有效的电磁参数。结果表明,该结构在40.8~61.8GHz频段范围内的等效介电常数和等效磁导率均为负,绝对带宽达到21GHz,实现了宽频带特性。该研究结果为左手材料在毫米波通信中的应用提供了重要参考。
Based on the equivalent circuit model theory, a rectangular metal ring with two interlaced multi-opening is placed on one side of the dielectric substrate, and thus a new kind of material structure is formed. Its effectiv electromagnetic parameters are extracted via the theoretical analysis and simulation. The results show that, th effective permittivity and effective permeability of this structure are both negative in the spectral range of 40.8 61.8 GHz, the absolute bandwidth is up to 21 GHz, and the wideband characteristic is achieved. These result provide an important reference for the application of left-handed materials in millimeter wave communication.
