RF recognition card reader with multi-dimensional antenna array

Abstract

The present invention provides a radio frequency identification card reader (RFID Reader) device with a multi-dimensional antenna array, which uses an electronic circuit to change the antenna (Antenna) or coil (Coil) of the radio frequency identification device to form a multi-dimensional antenna array (Antenna) Array), so as to use the scanning method of radio frequency identification technology to detect the identification code (ID code) of the radio frequency identification tag (RFID Tag) device, and can actively identify the position of the radio frequency identification tag device through this scanning method advantage. Therefore, the present invention provides a radio frequency identification card reader device with a multi-dimensional antenna array, which can scan multiple radio frequency identification tag devices and effectively identify the location of the radio frequency identification tag devices.

Description

technical field [0001] The invention relates to a radio frequency identification card reader device, in particular to a radio frequency identification card reader device with a multi-dimensional antenna array. Background technique [0002] Products related to radio frequency identification systems have gradually been widely used in industrial, military, and people's livelihood applications such as commodity barcodes, logistics management, consumer electronics, biomedical sensing, and mechanical assembly. Revolutionary impact on the lives of the general public. Although the principle of this technology was proposed by Maxwell in the middle of the 18th century, after more than 100 years of development, it has matured, but its related applications have only been integrated into human life in recent years. Due to the reason, the reason why radio frequency identification technology can flourish, in addition to the maturity of manufacturing process and design technology, the more...

Problems solved by technology

[0004] The radio frequency identification system of the above-mentioned known technology, in the resonator 15 part, all is to do one (radio frequency identification system card reader) to many (radio frequency identification label device) system application with an antenna 105 and several radio frequency identification tag devices, However, its main disadvantage is that it can only "passively" wait for the approach of a radio frequency identification tag device within the electromagnetic field range covered by this antenna.
