In this paper, the detailed design of the 1.8 GHz band 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 proposed and presented. The HFSS is used to simulate designed 1.8GHz band circulator to check the non-reciprocal characteristics at operating frequency range and the results are compared with the experiment data. From these measurement results, We confirm that the proposed Y-junction stripline circulator using center conductor with filter circuit is effective in achieving very high attenuations below of -30 dB at 3rd order harmonics.
