运用左右手传输线的后向波理论,提出了一种新型的小型化微带贴片八木天线。该天线的有源振子部分采用左右手传输线结构;同时,为了进一步减小其物理尺寸,反射器和引向器分别采用了弯折线和微带线加载电容的结构来实现。实验结果表明,此天线的电性能优于传统八木天线,且尺寸只有传统天线的1/3。经测试,这种天线在性能上不亚于传统的八木天线。
By using the backward wave theory of left and right hand transmission line, a new miniaturized microstrip patch Yagi antenna is proposed. The active oscillator part of the antenna adopts the structure of the left and right hand transmission lines. In the meantime, in order to further reduce its physical size, the reflector and the director adopt the structures of the bending line and the microstrip line loading capacitor respectively. The experimental results show that the electrical performance of the antenna is better than the traditional Yagi antenna, and the size is only 1/3 of the traditional antenna. Tested, the performance of this antenna is no less than the traditional Yagi antenna.
