Abstract
In this paper, we introduce an RFID planar coil whose inductance does not change when it is attached on the metal surface. The coil is designed considering the inductance reduction on metal surface so that the inductance is the inverse times the reduction rate, and copper pour is placed in the bottom layer of the coil. This coil configuration is very simple and effective in constructing RFID systems for managing objects with metal surface because it prevents inductance reduction on metal surface.
