PACS numbers: 07.05.Hd, 75.50.Gg, 81.07.Oj, 84.40.Az, 85.70.Ge, 85.85.+j

This paper presents a new design of an irregular hexagonal circulator with coplanar topology. The proposed coplanar circulator has an irregular hexagonal central conductor operating at the low frequency of 7–10 GHz. Yttrium iron garnet (YIG) is used in this circulator as the magnetic material that confer the nonreciprocity. This structure is analysed by high-frequency structure simulator (HFSS), which is based on finite-element method, to check all nonreciprocal transmission characteristics at the operating frequency. The results obtained show a good agreement with those developed in the literature.

Key words: circulator, S-parameters, yttrium iron garnet, nonreciprocity, waveguide, hexagonal structure.
