A triangular Y-j unction coplanar circulator based on Co nanowire array is designed and simulated in HFSS. Co nanowire array is modelled as ferrite with properties extracted from vibrating sample magnetometer (VSM) and ferromagnetic resonance (FMR) measurement. The circulator consists of printed circuit on Duroid board and nanowire array placed on top of the Y-junction. The simulation results show that with proper estimation of magnetic properties, a circulator can be achieved with 30.9 dB isolation, 2.1 dB insertion loss and 15 dB bandwidth of 1.7 GHz at 28.7 GHz.
