Abstract

The invention discloses a voltage doubling rectifying antenna with a harmonic suppression function, and relates to the technical field of microwave antennas. The rectifying antenna of the present invention is composed of two parts, a receiving antenna and a rectifying circuit. The rectifying antenna of the present invention can receive radio waves in space and convert them into DC energy for use by electronic devices; wherein the receiving antenna receives 2.4GHz electromagnetic waves, converts them into DC signals through a rectifier circuit, and finally obtains usable DC energy through a DC filter circuit ; The receiving antenna has a harmonic suppression function, which can effectively block harmonic radiation and improve rectification efficiency. The DC signal transformed by the rectifying antenna of the present invention can make the output voltage double the input voltage after passing through the voltage doubler and rectification part of the rectifier circuit, and can be used by components such as low power sensors.

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...
