摘　　要：该文提出一种基于谐振器慢波传输线的小型化宽阻带谐波抑制功分器,该谐振器慢波传输线由矩形谐振器、T型谐振器和蛇形线构成,来取代功分器中的1/4波长传统微带传输线。所设计制作的功分器,其尺寸仅为传统微带功分器的37.4%。实验结果表明,该功分器回波损耗大于10 dB的带宽范围为0.1~1.19 GHz,在2.2~11.05 GHz频率范围内衰减大于20 dB,具有较宽的阻带从而具有抑制谐波效果。仿真和测试结果较为吻合,验证了所提设计方法的有效性。A compact power divider with ultra-wide stopband for harmonic suppression based on resonator slowwave transmission lines is proposed in this paper.The resonator slow-wave transmission line is consisted of rectangular resonators,a T-type resonator and serpentine lines,and it is used to replace the conventional quarter wavelength transmission line of the power divider.The proposed power divider is only 37.4%size of the conventional microstrip power divider.The experimental results show that the bandwidth of return loss greater than 10 dB is 0.1 GHz~1.19 GHz.In the range from 2.2 GHz to 11.05 GHz,the attenuation is more than 20 dB,so the power divider has an ultra-wide stopband with harmonic suppression performance.The simulations agree well with the measured results,verifiy the feasibility of the proposed design method.
