The invention relates to an antenna, especially to an antenna apparatus and a security and protection system including the same. The antenna apparatus comprises an upper housing, a lower housing and an antenna. The antenna apparatus is characterized in that the apparatus also includes: an antenna cavity, which is arranged between the upper housing and the lower housing and is used for placing the antenna and enabling the antenna to receive and transmit a variable frequency signal; and rotating shafts, which are arranged at the sides of the upper portions of the upper housing and the lower housing and are used for adjusting the angle of the antenna. And a circular hole for antenna passing is arranged at the centers of the rotating shafts. According to the invention, the antenna apparatus employs plastics and flexible metal wires, wherein the plastics and the flexible metal wires are welded by an ultrasonic way; and metal wires are arranged between the plastic upper housing and the plastic lower housing. In addition, reinforcing ribs are arranged at the upper housing and the lower housing and divides the antenna into several segments, so that the antenna can be rotated after being installed in a product and relates signal intensity can be adjusted during rotation. Because the antenna is divided into several segments by the plastic housings and intervals of all the segments are different, the antenna apparatus has the good receiving-transmitting effect for variable frequency signals.
