Abstract

Abstract

A compact power divider with ultra-wide stopband for harmonic suppression based on resonator slow-wave 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.
