The present invention relates to a slide type mobile communication terminal having an antenna, and more particularly, to a slide type mobile communication terminal having an antenna having an antenna pattern formed on a slide member.

In general, the term "mobile communication terminal" refers to a device that a user can carry out wireless communication with the other party. These mobile communication terminals are classified into various types in appearance. For example, it is classified into a bar-type, a flip-type, a folder-type, or a slide-type mobile terminal according to its appearance. In recent years, the terminal is also important in functionality, but in consideration of the design to slim or miniaturized, and the number of users using the slide-type terminal is increasing.

The rapid development of mobile communication and satellite communication has made the role of wireless communication more important in the information society. The technology that forms the basis of such wireless communication is the antenna technology, and its importance is increasing day by day because the performance of the communication determines the quality of communication.

In particular, in the case of the antenna 6 used in the slide type mobile communication terminal including the slide unit 1 and the main body unit 2, the slide unit 1 is pushed up by sliding the main body unit 2 during the call. In this case, the pushed-up slide unit 1 blocks the antenna 6 provided in the main body unit 2, thereby affecting the performance of the antenna 6 having radiation characteristics, thereby causing a relatively low call success rate. There is.

In addition, in the slide type mobile communication terminal, the slide module 5 is typically made of a metal material, and the antenna 6 adjacent to the slide module 5 is made of a metal material constituting the slide module 5. As a result, the reception sensitivity is deteriorated.

The present invention has been invented to solve such a problem, and the antenna connected to the main body of the slide type mobile communication terminal can be prevented from interfering with the radiation characteristics of the antenna by being obscured by the slide raised by the main body. In addition, an object of the present invention is to provide a device capable of overcoming a decrease in sensitivity of an adjacent antenna by a slide module made of a metal material.

FIG. 2C is a side cross-sectional view illustrating FIG. 2B from the side.

As shown in Figures 2a, 2b, 2c, the slide type mobile communication terminal of the present invention is composed of a slide portion 10 and the main body portion (20). The slide unit 10 is provided with a first slide member 100, the body portion 20 is provided with a second slide member 200, the first slide member 200 and the first slide member. As the screw 200 is assembled to the assembling holes 11, 110, and 210, the 200 is slidably fastened to each other.

According to this structure, the slide unit 10 can be slid up and down on the body unit 20 to be switched to the open mode or the closed mode, and the slide unit 10 is normally raised upwards of the body unit 20 The lower part is exposed, and the main body 20 is provided with a key panel (not shown).
