| 摘 要： | 设计一个金属管道中无缆探测微机器人微波供电系统,系统利用微波在圆波导中的传输基本原理,解决微波在工业不锈钢管道（直径20 mm）传输中的极化和能量传输的不稳定性问题.管道中微机器人供电单元——整流天线接收微波能量并转换成直流作为其电源,接收天线采用圆极化微带贴片天线,整流电路采用倍压电路以提高输出功率,最终试验测得在24.5 dBm输入功率下（直流负载为300Ω）,整流输出86.8 mW直流功率,能够保证机器人驱动电机正常工作。

| Abstract: | 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（300 Ω）,and this power enables the micromachine to work well. |
