Abstract
An antenna includes a polyhedral dielectric material, a feed loop, a polygonal radiating patch, and shorting plates. The feed loop is electrically connected with a radio frequency identification (RFID) tag chip for supplying power to the RFID tag chip. The polygonal radiating patch is magnetically coupled with the feed loop for radiating the electromagnetic waves. Each of the shorting plates disconnects the radiating patch and a ground surface and controls the magnetic coupling of the radiating patch and the feed loop. Accordingly, an RFID tag that can be attached to a metal material is provided.
