The electronic seal with radio frequency identification of the present
invention comprises a lock cylinder and a lock latching plug to form an
integral lock portion, which having RF chip, RF antenna with associated
electric circuits, conductors and RF chip, wherein the lock cylinder
comprises a metal lower antenna tube and a metal upper antenna tube to
form each opposite pole of the dipole antenna. With relay conductor and
propagating conductor being built in the central hollow space to connect
with RF antenna and RF chip respectively, the RFID system is activated if
lock cylinder and lock latching plug joint together.
