In this paper, the detailed design of the Y-junction stripline circulator with the low pass filter circuit in the center conductor in order to higher attenuations below value of -30 dB at 3rd order harmonics is presented. The HFSS is used to simulate 1.8GHz band circulator and the results are compared with the experiment data. These results confirm that the designed Y-junction stripline circulator is effective in achieving high attenuation below -30 dB at 3rd order harmonics.
