| 摘 要： | 为了测试所设计的2.45 GHz RFID标签天线受环境影响情况,进行了天线周边分别有塑料瓶水、玻璃瓶水、金属罐头瓶水时的天线匹配特性测量,结果表明,塑料瓶水和玻璃瓶水对天线匹配性能的影响类似,主要是改变了天线的谐振频率,距离天线越近,对天线的谐振频率影响越厉害,导致天线的谐振频率向低端偏移.金属罐头瓶距离天线很近,如0.3 cm严重影响,导致天线不工作,当所有物体距离天线的位置超过5 cm时,则对天线性能影响不大.

| Abstract: | In order to measure the surrounding objects effect to RFID antenna,a 2.45 GHz printed dipoleantenna is measured when the water in plastic bottle,glass bottle and metal bottle are surrounding it indifferent distance,respectively.The results showthe effect of the water in a plastic bottle and in a glassbottle to the antenna is si milar,which mainly changes the antenna resonant frequency.The nearer to theantenna,the greater the effect of resonant frequencytolower.The antenna will be affected seriously whenthe metal canis near toit and will stop working when the distance less than 0.3cm.The effect will disap-pear when the distance between the antenna and the objects is more than 5 cm. |
