Hot issues of RFID electronic tag antenna
▼
In the design of RFID electronic tag antenna, in addition to the problem of reducing the physical size, buhottert also to further improve the bahotpotndwidth and ghot是什么意思ain characteristics of the miniaturized antenna, expand its practical application range, across the analysis of the polarization characteristics of the miniaturized antenna, celectronic翻译larify its polarization purity is also an imelectronic怎么读音portant research direction. In addition, the composite antenna design covering a variety of f踏歌广场舞requencies, multi-tag antenna optimal allocation technology, reader intelligent beam scanning anten踏歌广场舞na array technology, design simulation software and platformantennae英语怎么读, tag antenna and attrfid系统由哪几部分组成achment medielectronics是什么意思中文翻译a matching technology, consistent anti-interference and safety and reliability technology are worth further research.
Among them, on-chip antenna technologyhotel什么意思 is a hot topic in rechotmail邮箱登录ent years. Wantennasith the continuous expansion of RFID technology applicatio塔沟武校ns, RFID eletag是什么意思啊ctronic tags are inelectronics是什么意思中文翻译creasingly required for miniaturization, lightweight, multag是什么意思啊ti-function, low power consumption and low cost. However, the current RFelectronic什么意思ID electronic tags still use off-chip independent antennas, which have the advantages of high Q valuhot的比较级e, easy manufacturing and moderate cost. The disadvanelectronic去掉ic单词tage is that it is large and fragile, and cannot be used in the form of biological tags for anti-counterfeiting or implanted in animals. If the antenissuesna could be integrated into the tag chip, it could work wihotel什么意思thout any external devices, which would make thehot entire tag smaller and easier to use,
Integrating the antenna into the chip not only siantenna翻译中文mplifies the origi他惯会撒野nal e-tag production process, reduces costs, but also improves reliabirfid应用实例lity. As an energy receiver and signal seelectronic去掉ic单词nsor, the on-chip antelectronics是什么意思中文翻译enna determinesantenna翻译 the performancissue什么意思e of tantenna公司he whole system. Its basic starting point is the use of Faraday el踏歌行ectromagnetic induction princiissue是什么意思英语翻译ple. Trfid是什么技术he external magnetic field energy is converted into the on-chip power supply voltage, which serve他惯会撒野s as the working power supply of the whole chip. Meanwhile, the on-chip current or voltage change caused by the electromagnetic field change iselectronically used to identify the received signal. Brfid标签衣服要剪掉吗y changing thot的比较级he external magnetic field caused by itshotter own output impedance, the signal is transmitted to the receiver. So far, the on-chip antennas implehot的比较级mented on standard CMOS technology still use silicrfid是什么意思on-based integrated spiral inductors ahotpots the main s塔沟武校收费标准2021tructure.
