A compact quasi-Yagi antenna with bent arms and split-ring resonators (SRRs) is proposed. Compared with traditional quasi-Yagi antennas employing straight arms, the resonant frequency of the proposed antenna could be always consistent with its center frequency, and there is no obvious frequency shift under the process of its miniaturization. The SRRs are adopted in the proposed compact antenna for a high gain of 6.58 dBi. The reliability verification of the proposed antenna radiation characteristics is further experimentally proved with the prototype measurement. The proposed quasi-Yagi antenna has an adjustable compact structure and low frequency offset and could be used in the precise point-to-point wireless communication environment.

利用弯曲臂和开口环谐振器的高增益紧凑型准八木天线

提出了一种具有弯曲臂和开环谐振器（SRR）的紧凑型准八木天线。与采用直臂的传统准八木天线相比，所提出的天线的谐振频率可以始终与其中心频率一致，并且在其小型化过程中没有明显的频移。在建议的紧凑型天线中采用了SRR，以实现6.58 dBi的高增益。原型测量进一步验证了所提出的天线辐射特性的可靠性。所提出的准八木天线具有可调节的紧凑结构和低频偏移，可用于精确的点对点无线通信环境。
