Abstract

At least one omni-directional antenna and at least one directional antenna are both disposed inside the RFID book management security gate, in which the omni-directional antenna can broaden a detection angle and reduce leaky wave of an electromagnetic wave in the library; and the directional antenna strengthens the detection of the case that a book or reference material is grasped, carried under the arm or attached to the body, so as to achieve an objective of effective and security management for the book or reference material. When a user carries the reserved book or reference material through the security gate, an RFID tag on the book or reference material can be effectively detected, which can avoid that the book or reference material without a borrowing procedure is furtively taken away.
