In order to improve the isolator of microstrip devices,a single-side magnetic field microstrip isolator with high isolation and high temperature stability are designed according to the design theory of microstrip circulator.Based on the analysis of the working mode of microstrip devices,a new circuit structure of silted hexagon junction matching rectangular open load is designed.The test result show that in the operating frequency band of 11 to 11.4 GHz and the temperature range is-55 to+85 ℃,the X-band single-side magnetic field microstrip isolator designed with rectangular open load circuit structures matched by silted hexagon junction has the insertion loss less than 0.3 dB,the VSWR less than 1.3,the isolation greater than 23 dB,meeting the design requirements.
