提出了一种由宽边耦合分裂环谐振器(SRR)和激励弧形单极子组成的自谐振小型化天线。天线的尺寸及其谐振频率基本上由SRR的尺寸和几何形状决定，而谐振处的输入电阻由单极子的弧长决定。给出了直径为1/23.4波长(ka类似于0.134)的天线结构的数值计算和实验结果。在没有任何匹配网络的情况下，天线调谐到50欧加，测得其效率为17.5%。
A self-resonant miniaturised antenna composed of a broadside-coupled split ring resonator (SRR) and an excitation arc-shaped monopole is presented. The size of the antenna and its resonance frequency is essentially defined by the SRR dimensions and geometry, while the input resistance at the resonance is governed by the arc length of the monopole. Numerical and experimental results are presented for an antenna configuration of 1/23.4 wavelength in diameter (ka similar to 0.134). The antenna is tuned to 50 Omega without any matching network, and its efficiency is measured to be 17.5%.
