摘要: 由于RFID标签植入轮胎中,受轮胎介电常数的影响而使得电磁波信号在传输过程中损耗严重。本工作针对一款螺旋弹簧式的RFID标签,将轮胎介电常数与植入轮胎中的RFID标签的传播性能进行分析并仿真预测,得出轮胎的介电常数与天线增益是正比的关系,而与反射系数成反比关系。从而为植入轮胎中的RFID标签的植入环境提供了依据。

Abstract: Since the RFID tag is implanted into the tire, the electromagnetic wave signal is severely damaged during the transmission by the influence of the tire dielectric constant.For a suitable RFID tags the propagation properties of tire dielectric constants and RFID tags in implanted tires are analyzed and simulated in this paper. The dielectric constant of the tire and the antenna gain is proportional to the relationship, and it is inversely proportional to the reflection coefficient. So that it is implanted in the tire RFID tag implanted in the environment provided.

Key words: tire; RFID tag; electromagnetic simulation; gain; reflection coefficient
