英文摘要：

Design of an 8mm waveguide magic T is introduced; simulation and calculationto the waveguide magic T is conducted with 3D simulation software. Equal power division has been realized within 32GHz to 37GHz. Isolation between terminals is better than 30dB; voltage standing wave ratio （VSWR） is less than 1.2 and power difference between equally divided arms is less than 0.06dB.
