Miniature Triangular Circulator with Coplanar Waveguide Structure

Abstract

A different form of coplanar triangular circulator structures is proposed in this work. The HFSS is used to simulate the circulator and to check the non-reciprocal characteristics at operating frequency. In this analysis, an insertion loss of-0.21 dB and an non-reciprocity of-33 dB appeared at around 13.5 GHz; these results show good circulation performances of the device. The miniaturization of device need to have a small size which it is a principal advantage of a coplanar triangular circulator. 
