Abstract

The invention discloses a voltage-doubling rectifying antenna with a harmonic suppression function. The voltage-doubling rectifying antenna relates to the technical field of microwave antennas. The voltage-doubling rectifying antenna comprises two parts including a receiving antenna and a rectifying circuit. The rectifying antenna can receive radio waves in the space and convert the radio waves into DC energy for electronic devices to use, wherein the receiving antenna receives 2.4 GHz electromagnetic waves, the 2.4 GHz electromagnetic waves is converted into a DC signal by means of the rectifying circuit, and finally usable DC energy is obtained by means of the DC filtering circuit; and the receiving antenna has the harmonic suppression function, can effectively block harmonic radiation and improve the rectification efficiency. After the DC signal converted by the rectifying antenna passes through a voltage-doubling rectifying part of the rectifying circuit, an output voltage becomestwice the magnitude of an input voltage and is used by components such as a low-power sensor.

Description

technical field [0001] The invention belongs to the technical field of microwave antenna technology, and in particular relates to a voltage doubler rectifying antenna with harmonic suppression function. Background technique [0002] In recent years, microwave wireless power transmission has received more and more attention. Microwave energy transmission has the characteristics of low loss and high transmission efficiency, and it can be applied to drones, robots, micro sensors, biomedicine and other fields. The rectenna is the core component of the microwave energy transmission system. As the receiving front end of the microwave energy transmission system, the rectenna affects the receiving, transmission and conversion efficiency of the entire system. Microstrip antennas are widely used in the design of receiving antennas for rectennas because of their small size, light weight, flexible polarization, easy integration, easy formation, and easy processing. Adding the harmoni...
