Low-profile miniature microwave energy transmission rectifier

Abstract

The present invention discloses a low-profile miniature microwave energy transmission rectifier. The low-profile miniature microwave energy transmission rectifier comprises at least one rectificationmodule, and each rectification module comprises one frequency selection surface layer, one metal floor layer and one rectification circuit layer which are arranged in order from front to back; each frequency selection surface layer, each metal floor layer and each rectification circuit layer are separated from one another by two substrates; each frequency selection surface layer is connected witheach rectification circuit layer through one metal via hole penetrating each metal floor layer and each substrate, and each metal via hole and each metal floor layer are insulated to each other; eachrectification circuit layer comprises one diode, one wire and one output end; and each metal via hole is connected with the anode of each diode through each wire, and the cathode of each diode is connected with each output end. The low-profile miniature microwave energy transmission rectifier can achieve high-efficiency transmission of electromagnetic wave energy and can meet requirements of low profile, miniaturization and low cost.

Description

technical field [0001] The invention relates to a microwave energy conversion device, in particular to a low profile small microwave energy transmission rectifier. Background technique [0002] The energy supplied by the sun to the earth per second reaches 4.1×1013 kcal, which is equivalent to the energy emitted by burning 5 million tons of high-quality coal per second. The solar energy lost in space is 2.2 billion times more than the energy supplied to the earth. Establish a solar satellite base in space, convert the continuous clean solar energy into electrical energy, then convert the electrical energy into microwave energy of appropriate frequency, and then radiate it to the earth by the transmitting antenna, and receive the energy by the rectification component, and finally pass through the rectification component Convert microwave energy into direct current energy that can be conveniently used and stored. [0003] Wireless microwave power transmission (MPT) is mainly...

AI Technical Summary

Problems solved by technology

The rectification component that receives electromagnetic energy is the key technology of the MPT system. The early receiving rectification is generally a parabolic antenna or a horn antenna, but the antenna is heavy and bulky. Since then, half-wave dipole antennas made of aluminum strips are often used for Reception, although the weight and volume of the receiving antenna has been reduced to a certain extent, it still cannot meet the miniaturization requirements and is difficult to popularize and apply
