| 摘 要： | 设计一种带有开口谐振环(SRRs)引向器的新型端射天线。天线由反射板、地板、辐射单极子和开口谐振环组成。天线的反射板结构使天线在低频处阻抗匹配，有效地提高了天线带宽；用六对开口谐振环结构作为天线的引向器，很好地实现了天线的高增益。仿真和实测结果表明，天线阻抗带宽达到73.7%(2~4.21 GHz)，增益为4.3~10.3 dB；在天线的带宽内，天线的辐射方向图稳定，设计的天线满足S波段无线通信领域的需求。

| Abstract: | A novel end-fire antenna with Split-Ring Resonants(SRRs) is designed. The antenna consists of a reflector, a floor, a radiation monopole and SSRs. By using the reflector structure, the impedance matching of the antenna is realized at low frequency, and the bandwidth of the antenna is improved effectively. The six pairs of SSRs structure are used as the director of the antenna to achieve the high gain of the antenna. The results of simulation and measurement show that the impedance bandwidth of the antenna is 73.7%(2~4.21 GHz), the gain is 4.3~10.3 dB.The radiation pattern of the antenna is stable within the bandwidth of the antenna. Therefore, the designed antenna meets the requirements of S-band wireless communication field. |
