Description of the Invention: [Technical Field of the Invention] The present invention relates to a monopole (Monopo 1 e) antenna structure, and more particularly to a symmetric slot monopole antenna. [Prior Art] With the advent and development of the era of wireless communication, the design of many communication products tends to be miniaturized. In order to comply with this design trend, the size and size of the antenna should also be reduced, and the micro antennas currently in common use. There are planar antennas and chip antennas, where the planar antennas are designed with a 'type' microstrip antenna (micr〇_strip an^enna), printed antenna or inverted F Type antenna (Planar inverted-F antenna 'PIFA), etc. In general, printed circuit board type dipole antennas are often used in wireless communication products, and the structure of dipole antennas is taken as an example. The ends are each extended, so that the antenna structure length is long, and the volume of the wireless communication product is limited by the size of the antenna, which is difficult to be miniaturized, and the printed circuit board type antenna has a relatively high production cost and high manufacturing cost. . In addition, in order to improve the speed of wireless transmission, a multi-wheeling year has been favored by users. It is mainly used to connect two signals, and is connected to the signal processing switching circuit, respectively, and the = f line is broken. The two antennas are responsible for receiving/transmitting, and only the antenna is responsible for the connection of the current type to achieve the purpose of improving the wireless transmission speed, and the structure of the antenna is to provide a symmetrically shaped antenna structure. In view of the above problems, the main slot monopole antenna of the present invention adopts a metal material and an integrated 1280692 2 brush-type antenna structure, which is low in manufacturing cost and enhances the manufacturing convenience line, and aims to symmetry of the present invention.
