This paper designs a microwave energy supply system for in-metal-pipe inspection micromachines. Based on the theory of microwave transmission in circular waveguide,this system solves the problems of the pipes polarization and microwave power transmission in stability.As the power supply unit for micromachine, the rectenna receives microwave power and converts it to DC.A circularly polarized microstrip patch antenna is used as the receiving antenna.In order to improve output power,the circuit applies four doubler circuits as its rectifying circuit.With an input power level of 24.5 dBm,the end testing output power is 86.8 mW(300Ω),and this power enables the micromachine to work well.
