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. 

“…However, these circulators have a large circuit size and are not accessible to integrate. In Benevent and colleagues, [14][15][16] stripline circulators have been extensively studied, with low losses and easy integration. This circulator has the potential to handle high power.…”

In this letter, a compact suspended-stripline circulator with high powerhandling capability has been proposed. The presented double-knotted circulator is constructed by folding the structure through an air-filled microcoaxial line. Power-handling capability is increased using a single-sided ferrite disc and dielectric loading at the central junction. Moreover, another Y-junction shorted to the ground is coupled on the other side of the substrate to improve the circuit impedance matching. The equivalent circuit model and high power characteristics of the suspended-stripline circulator are proposed and analyzed. An X-band double-knotted circulator has been designed, simulated, fabricated, and measured. The measured results show a reasonable agreement with the simulated ones.

“…Y-junction ferrite circulators are important devices in today microwave circuits and have been studied in literature in recent years [1][2][3][4][5]. This significance is initiated and spread out from the directional properties of ferrimagnetic devices allowing the control of microwave signals through a bias magnetic field [6].…”
