Microwave energy transmission resonance robot antenna design method

Abstract

The present invention discloses a microwave energy transmission resonance robot antenna design method. The method comprises the following steps: the step 1: introducing the basic structure and a working principle of a rectification antenna, and employing and designing a yagi antenna and a baffle-board antenna having high directionality antennas to take as receiving antennas; the step 2: employing a piecewise linear method to derive a rectifying circuit model in the large-power condition so as to obtain the relation of the input power and the output voltage and the relation of the rectification efficiency and a duty ratio; the step 3: providing a step-changing coplanar strip line as a filter matching network, and performing modeling design; and the step 4: performing test of the rectification antenna. The microwave energy transmission resonance robot antenna design method tests the rectification antenna to prove high orientation performance of the rectification antenna and verify the model correctness and the feasibility of the design method so as to lay the foundation of the application of the rectification antenna.

[0002] Micro-robots refer to robots with small structural dimensions, precise devices, and fine-tuning operations. Due to their small size, low cost, ability to work in extreme environments and small spaces, and group collaboration, they are used in some military and civilian applications. Broad application prospects, such as using micro-pipeline robots to enter the criss-cross and vertically connected building ventilation ducts for disaster site investigation, enemy reconnaissance, or entering narrow tubular passages or gaps in space for detection, maintenance and other operations; using micro-medical robots to treat the human body , intestinal non-invasive diagnosis and treatment, etc., so the research on micro-robot technology is currently a hot spot in the world; Miniaturize the robot; among them, the miniaturization of the driver, sensor, control drive circuit, energy supply and other parts is the key to the research in this field; the energy supply of conventional robots is generally powered by cable or battery, and the power supply by cable is used. For micro-robots, compared with the traction force of micro-robots, the towline force cannot be ignored, which seriously affects the operation performance of micro-robots. However, if the battery-powered method is used, the power supply performance will drop sharply due to the shrinking of the battery size, which cannot meet the requirements. The demand for continuous operation of robots, wireless energy transmission has the advantages of continuous energy supply, cable-free operation, etc., which just meets the supply and demand of micro robots
