本文提出了一种廉价、高效且电小的天线设计，该天线基于二维（21）超材料启发结构，由电小矩形半回路天线驱动，该天线同轴馈送通过有限的PEC接平面。实测反射系数与模拟数据吻合良好，谐振频率与数值预测值仅相差0.5%。所提出的二维天线系统随频率线性扩展，并预测了天线系统在300、430和1580 MHz的辐射特性。(C) 2007 Wiley期刊公司
Inexpensive, efficient, and electrically-small antenna designs are presented, which are based on a two-dimensional (21) metamaterial-inspired structure driven by an electrically-small rectangular semiloop antenna that is coaxially-fed through a finite PEC ground plane. Measured reflection coefficients showed a very good agreement with the simulated data, where the measured resonant frequency is only 0.5% different from the numerically predicted value. The proposed 2D antenna systems are linearly scalable with frequency, and predicted radiation characteristics of the antenna systems at 300, 430, and 1580 MHz are reported.
