【摘要】:作為5G三大應用場景之一的物聯(lián)網(wǎng)業(yè)務擁有廣闊的市場前景,射頻識別(RFID)技術作為物聯(lián)網(wǎng)中的關鍵技術也將發(fā)揮重大作用。標簽是RFID系統(tǒng)重要組成部分,它的性能直接影響了系統(tǒng)的整體效益,傳統(tǒng)RFID系統(tǒng)中的標簽都含有芯片,標簽的價格居高不下,因此研究低成本的無芯片標簽具有重要意義。論文的主要任務是研究RFID系統(tǒng)中無芯片標簽的設計方法,完成的主要工作如下:(1)設計并實現(xiàn)了一種編碼容量為4比特的U型線極化RFID無芯片標簽,采用HFSS仿真軟件對標簽結構進行了仿真驗證,并利用頻率選擇表面原理對標簽的性能進行進一步的完善,最后確定了標簽的最佳結構參數(shù),對實物進行了加工和測試。(2)設計并實現(xiàn)了一種編碼容量為8比特的雙極化RFID無芯片標簽,該標簽是在線極化標簽的結構基礎上進行改進,標簽能工作于水平極化和垂直極化兩種狀態(tài),并且這兩種工作方式互不干擾,有效地提高了標簽的編碼效率。同樣采用HFSS仿真軟件對標簽進行仿真,將頻率選擇表面原理運用于完善標簽的性能,確定標簽的結構參數(shù)。然后對設計的標簽進行了實物加工和測試。(3)設計了一種編碼容量為3比特的圓極化RFID無芯片標簽,標簽工作于左旋圓極化和右旋圓極化狀態(tài),因此標簽對入射波的入射角度不敏感,在實際應用中也有更好的實用價值。采用CST仿真軟件對設計的標簽結構進行了仿真優(yōu)化,采用頻率選擇表面原理對標簽的性能進行完善,最后對所設計的三款標簽進行了比較。
[Abstract]:As one of the three application scenarios of 5G, Internet of things (IoT) business has a broad market prospect, and RFID RFID-technology will play an important role as the key technology in IOT. Tag is an important part of RFID system, its performance directly affects the overall efficiency of the system. The traditional RFID system labels contain chips, and the price of tags is high. Therefore, it is of great significance to study low cost non-chip labels. The main task of this paper is to study the design method of chipless label in RFID system. The main work is as follows: 1) Design and implement a 4-bit U-shaped line-polarized RFID chip free label. HFSS simulation software is used to verify the label structure, and the performance of the label is further improved by using the principle of frequency selection surface. Finally, the optimal structural parameters of the label are determined. A dual-polarization RFID chip free label with coding capacity of 8 bits is designed and tested. The label is improved on the basis of the structure of on-line polarization tag. The label can work in both horizontal and vertical polarization states, and these two working modes do not interfere with each other, so the coding efficiency of the tag is improved effectively. The HFSS simulation software is also used to simulate the label. The principle of frequency selection surface is applied to improve the performance of the label and the structural parameters of the label are determined. Then, the designed label is processed and tested. (3) A 3 bit circular polarized RFID chip free label is designed. The label works in the left circle polarization and the right circle polarization state. So the tag is insensitive to the incidence angle of incident wave and has better practical value in practical application. The label structure is simulated and optimized by using CST simulation software, and the performance of the label is improved by the principle of frequency selection surface. Finally, the three labels are compared.
