提出了四种一维曲折微带线结构，以实现一维分布式传输线模型，用于设计可隐藏大于波长的物体的地毯斗篷。根据模型的设计理论确定了所提出结构的线长，并利用所提出的结构设计了一种可隐藏平面上周期性排列的大三角形区域的地毯斗篷。进行了全波模拟，并从计算结果证明了宽带操作和设计的有效性。
Four types of one-dimensional (1-D) meander microstrip-line structures are proposed in order to realize 1-D distributed transmission-line models for the design of carpet cloaks that can hide larger objects than the wavelength. The line length of the proposed structures is determined based on the design theory of the model and a carpet cloak for hiding periodically arranged large triangle areas on a flat surface is designed by using the proposed structures. Full-wave simulations are performed, and the broadband operations and the validity of the design are demonstrated from the calculated results.
