摘　　要：射频识别(RFID)应用中的天线设计需考虑的最重要因素是低价位、小剖面和小型化,而为了最大功率传输,天线的输出阻抗必须和其后的芯片的输入阻抗匹配。本文介绍一种新颖的简单结构折叠偶极子天线,所需的输入阻抗能通过选择合适的几何参数轻易获得,这对设计特殊阻抗的天线非常有用。Low cost, low profile and miniaturized size are the most critical factors needed to be consider ed in the design of antennas for RFID applications. For maximum power transfer, the input impedance of the antenna must be the conjugate of input impedance of the ASIC. in this paper, a novel folded dipole antenna with a very simple configuration is presented. The required input impedance can be achieved easily by choosing suitable geometry parameters. This is very useful to design antenna with special impedance.

关 键 词：折叠偶极子天线 天线输入阻抗 射频识别
