Design of Robust UHF RFID Tag Antenna for Free-space and Metal Surface

摘要：

　　Here, we present a robust RFID tag antenna with an appropriate structure that would operate adequately as a dipole in free space and as a relatively efficient microstrip antenna when placed on a metal surface. Good impedance matching is achieved by the use of a T-matching network in the both cases. For low-cost fabrication and simple structure, the antenna is printed on a single-layer substrate without a ground plane or shorting. The measured results show that the half-power bandwidth is 1 GHz (730 MHz1.7 GHz) and 110MHz (845 MHz955 MHz) when in free space and on the metal surface, and the both reading distances are about 8m measured by using a commercial measurement system.
