Patent ID: 8573495

Claim:
A radio frequency identification electronic device with enhancing surface wave-guide effect, comprising: a host or a programmable single IC; an identification transmitting and receiving device electrically wired or wireless connected to the host or the programmable single IC for generating a current; and an enhancing surface wave-guide coaxial cable structure connected to the identification transmitting and receiving device, and comprising a coaxial cable having at least one breach region without an outer conducting layer and a matching resistor connected to an inner conducting layer and the outer conducting layer of the coaxial cable, wherein the current flowing to the inner conducting layer of the coaxial cable builds up an electromagnetic wave, and the electromagnetic wave leaks out in the at least one breach region and the electromagnetic wave is transmitted along the outer conducting layer of the coaxial cable until to the matching resistor, such that a radio frequency identification electronic tag attached to an object is automatically triggered by an electromagnetic field within an effective range, and the radio frequency identification electronic tag transmits information stored therein to the host or the programmable single IC through the identification transmitting and receiving device.
