摘要：
A small UHF RFID tag antenna for metallic object using characteristic mode theory (CMT) is presented in this paper. The tag antenna is composed of a rectangle loop and the metallic object. The rectangle loop is used as an inductive coupler element (ICE) to excite a specified characteristic mode current of the metallic object. In this case, the metallic object itself will act as the main radiator. The loop is printed on the ceramic material with a high relative dielectric constant and placed at a current maximum of a desired mode. The satisfactory result proves that the desired characteristic mode has been partially excited by this small loop.
