A loop antenna is designed and fabricated for ultra-high frequency (UHF) near-field radio frequency identification (RFID) readers. The artificial mu-negative transmission line (MNG-TL) structure has been applied to the antenna design, which will help the current distribution along the loop to keep in phase even with the perimeter of the loop more than two operating wavelengths. Thus the antenna can...
There are many issues in traditional inland ship lockage operation, such as operation cumbersome, low-level efficiency and prone to waterway jam. In order to solve these problems, a relevant solution scheme based on Internet of Things technology is proposed in this paper. The ships used RFID tag can be identified automatically, wireless communication between readers and host machine can be realized...
