提出了一种电小尺寸可调谐裂环谐振器天线。天线的谐振取决于分裂环的谐振。通过在分裂环上加载变容二极管，可以降低天线的工作频率并进行调谐。通过施加1~9V的直流电压，该天线能够在365~500 MHz的频率范围内调谐，测得的反射系数为10美元分贝。该天线结构紧凑，外形低调。在365MHZ的工作频率下，它的测量结果是$0.095\lambda\x 0.046\lambda\x 0.001\lambda$，其中$\lambda$是自由空间波长。
An electrically small tunable split ring resonator antenna is presented. The resonance of the antenna is dependent on the resonance of the split rings. By loading the split ring with varactor diodes, the antenna operating frequency can be reduced and tuned. By applying a DC voltage of 1 to 9 V, the antenna is capable of tuning within the frequency range of 365 MHz to 500 MHz with the measured reflection coefficient of ${-}10$ dB. The antenna is compact and low profile. At the operation frequency of 365 MHz, it measures $0.095 \lambda \times 0.046 \lambda \times 0.001\lambda$ , where $\lambda$ is the free space wavelength.
