Problems solved by technology

[0005] However, antennas built into terminals, including planar inverted-F antennas, are designed with a predetermined height difference between the ground part and the antenna part, and are installed inside the terminal, so their characteristics are inferior to those of external antennas. It is more sensitive to ground conditions or other conditions of the terminal, so the antenna performance is difficult to stabilize

Abstract

The present invention discloses a slide cover style mobile communication terminal with built-in antenna pertaining to mobile communication tool. The invention, aiming at sliding cover type mobile communication terminal with a second shell sliding open / close along with the first shell, the invention comprises parts of a grounding part positioned on circuit board of the first shell; an antenna part sliding with the second shell, and converting between the grounding part superposition or non superposition states to appear different operation characters; a electricity supply wire being independent of the slide of the second shell, and always maintaining the connection electrically of the circuit board with the antenna part. The condition of operation character reduction caused by sliding upwards and downwards states of the terminal can be prevented by arranging internal antenna of he sliding cover terminal, and stable operation character can be achieved to offer best function.

Description

technical field [0001] The invention belongs to mobile communication tools, and particularly relates to a slide-type mobile communication terminal with a built-in antenna that maintains good working characteristics regardless of whether the terminal is in an open or closed state. Background technique [0002] The so-called mobile communication terminal refers to a mobile phone or PDA, etc. This mobile communication terminal receives and transmits signals with a base station installed near the terminal location, transmits information with a specific counterpart, and performs various value-added services. Therefore, in order to receive a transmission signal, it is mounted on an antenna in a mobile communication terminal. [0003] Moreover, antennas of such mobile communication terminals can be classified into built-in and external types according to the installation structure relative to the terminal. An example of a built-in antenna is given, such as a planar inverted F anten...
