Abstract
A radio frequency identification electronic device with enhancing surface wave-guide effect includes a host or a programmable single IC, an identification transmitting/receiving device electrically connected to the host or the programmable single IC for generating a current, and an enhancing surface wave-guide coaxial cable structure. The enhancing surface wave-guide coaxial cable structure comprises a coaxial cable having at least one breach region without an outer conducting layer and a matching resistor, wherein the current builds up an electromagnetic (EM) wave while flowing through the at least one breach region, and the EM wave is transmitted along the outer conducting layer of the coaxial cable until to the matching resistor. Moreover, an electromagnetic field can be built up while the current flows through the at least one breach region, and a RFID electronic tag attached to an object can be automatically triggered by the electromagnetic field.
