Through the integrated junction circulator on a ferrite substrate and TaN film load.designed a miniaturized microwave isolators. Using electromagnetic field simulation software HFSS to analyze and improve the design.With the result in 8~9 GHz,the isolation is greater than 20 dB, insertion loss less than 0.5 dB, the voltage standing wave ratio (VSWR) is less than 1.25.Design from the microwave isolators to achieve the indicators, and comply with the requirements of miniaturization and integration of microwave communication devices.
