Sliding lid type mobile communication terminal with built-in antenna

Abstract

The invention discloses a kind of built-in aerial slip lid mobile communication terminal, which is part of radio communication device field. In the upper frame built-in the built-in aerial and the mother board simultaneous, which bear built-in aerial that built-in the upper of upper self body and use to receive and transmit electrical wave signal; the mother board that built-in the upper of self body and proceed electrical connection with built-in aerial, make the mother board received and transmitted audio and video information by built-in aerial. The invention can prevent interference electric wave phenomenon when use build-in aerial in slip lid mobile communication terminal, can improve the property of receiving and transmitting and the convenience of mobile communication terminal.

Description

technical field [0001] The present invention belongs to the scope of wireless communication devices, and more specifically relates to a slide-type mobile with a built-in antenna that can prevent radio wave interference caused by using a built-in antenna in a slide-type mobile communication terminal and improve the performance of receiving and sending radio waves. communication terminal Background technique [0002] Generally speaking, a mobile communication terminal is a wireless communication device that allows users to make calls while moving. It can be roughly divided into flip type according to its appearance; A folder type that moves; a slide type in which the upper frame can slide. [0003] Recently, in addition to simple voice sending and receiving functions in mobile communication terminals, their multimedia functions have also been further enhanced, so an antenna for mobile communication terminals that can send and receive more information is required. [0004] An...

Problems solved by technology

[0010] However, in the slider-type mobile communication terminal with built-in antenna of the above-mentioned prior art, since the guide rail 26 of the above-mentioned frame 20 is usually made of metal material, when the above-mentioned upper frame 20 is slid upward to transmit and receive radio waves, the The above-mentioned guide rail 26 at the upper position of the built-in antenna 30 causes radio wave interference phenomenon, resulting in a decrease in radio wave transmission performance.

[0011] Considering the above-mentioned problems, in the prior art, the built-in antenna 30 is installed inside the slidable upper frame 20 to eliminate radio interference. The above-mentioned power supply line 36, and the frequent operation of the above-mentioned upper frame 20 will cause the above-mentioned power supply line to be disconnected from time to time, resulting in poor contact
