Abstract

Miniaturized Rat race coupler with good harmonic suppression using single shunt open stub unit is proposed in this paper. Presented structure which is simple to analyze using transmission line model achieved miniaturization of 56% with harmonic suppression up to 10f0 without any additional components. Circuit, EM simulated S-parameters of proposed structure are well matched. Further coupler also provides good FBWs.

Keywords: Single shunt open stub unit, Rat race coupler, size reduction, harmonic suppression.
