A Rubik's Cube for Harvesting Radio Frequency Electromagnetic Wave Energy Arrays Suitable for Mobile Phones and Wi-Fi

Abstract

The invention discloses a radio frequency electromagnetic wave energy collection array Rubik's cube suitable for mobile phones and wifi. The four sides of the device are surrounded by four array antenna patches, and the top surface of the device is an energy recovery board; the array antenna patches It is a ring array antenna with an air layer dielectric layer, consisting of 2*2 ring array elements, fed by microstrip lines, and each array element is opened with two pairs of symmetrical C-shaped rings to achieve dual-frequency for collection. 1.9GHz and 2.4GHz in the environment. The purpose of setting the antenna as an antenna with an air dielectric layer is to reduce the overall dielectric constant of the dielectric layer to achieve broadband. Broadband can make the frequency band of electromagnetic waves accepted and the more RF energy collected. When the energy cube of the present invention is in the open type, the electromagnetic wave energy in the surrounding environment can be collected. When the energy cube of the present invention is in an inner closed type, it can not only shield the damage to the human body caused by the radiation of the mobile phone, but also collect the radiation energy of the mobile phone.

Description

technical field [0001] The invention belongs to the field of electromagnetic wave energy collection antennas, and relates to the design of a multi-frequency and broadband array antenna and the design of a broadband matching circuit and a rectifying energy storage circuit. Background technique [0002] With the rapid development of electronic technology, various wireless electronic products are flooding people's production and life. In addition to wireless keys, Bluetooth headsets, mobile phones, etc., which are widely used in daily life, in the industrial field, a large number of wireless sensor nodes are distributed in various environments to transmit monitoring data in real time to facilitate industrial control and production; in some special environments , such as high-radiation, high-temperature, high-altitude, and high-cold regions, it is not convenient for humans to monitor directly, and wireless sensors can be installed to complete monitoring and real-time transmissio...

AI Technical Summary

Problems solved by technology

For some commonly used electronic products, such as Bluetooth headsets, wireless keys, temperature and humidity sensors, etc., battery replacement is relatively convenient; but for sensor nodes with a large scale and a large number in the Internet of Things, manual battery replacement will take time and effort

Especially for electronic equipment working in a special environment, it is not only troublesome and dangerous to replace the battery, and, with the miniaturization design of wireless electronic equipment, it is more and more inconvenient to replace the battery. increase environmental pollution
