Abstract
Description
The present invention relates to a portable terminal having a diversity antenna.
A portable terminal is a portable device that is portable and has one or more functions such as voice and video calling, information input and output, and data storage.
As the functions are diversified, the portable terminal may have complicated functions such as photographing a picture or video, playing a music or video file, receiving a game, or receiving a broadcast. These features can be integrated into a comprehensive multimedia player.
In order to implement complex functions, various new attempts have been applied to portable terminals in terms of hardware or software. In addition, a user interface environment is provided for a user to search for or select a function easily and conveniently.
One aspect of the development of information and communication technology includes a dramatic increase in the amount of data that can be transmitted and received and the transmission speed. To do this, the antenna needs to receive a large amount of wireless data in a clean quality while moving.
In the antenna design of a portable terminal for high-speed wireless data transmission, there is a problem of cancel out due to interference between signals received through different paths, and an antenna for solving this problem is suitable for the overall appearance of the portable terminal. They are required to have arrangements that meet the trend of light weight and simplification of portable terminals, which are being integrated at a high density.
An object of the present invention is to provide good radio performance by reducing the loss of radio data having a high data rate reached to the terminal while moving.
Another object of the present invention is to develop an antenna device capable of implementing diversity to reduce extinction between radio signals due to multipath.
Another aspect of the present invention is to allow such an antenna device to be easily applied to a portable terminal of a thin and simple form.
In order to achieve the above object, the present invention, the terminal body is provided with a circuit board is formed; A first antenna disposed on one side of the circuit board to feed the circuit board; A second antenna disposed at a predetermined distance from the first antenna to implement diversity of the first antenna; And a ground extension configured to allow the second antenna to be directly grounded and to extend a ground of the circuit board.
As a result, the second antenna to implement diversity can directly use the ground of the circuit board of the portable terminal, which is becoming smaller and smaller as it becomes lighter and shorter, thereby making it suitable for high-speed data transmission.
In particular, the second antenna which can use a wide ground can obtain a portable terminal having good wireless performance in a low band communication band by applying a flat antenna or an improved antenna.
In addition, as an object capable of extending the ground of a limited area of a small circuit board, an example using a metal sheet or the like surrounding a display module having a wide surface will be presented.
The invention also includes connecting means for accurate and reliable electrical contact with the object to extend the ground and technical considerations for it.
In the portable terminal according to the present invention configured as described above, since antennas capable of implementing diversity are arranged, radio characteristics are excellent. Furthermore, the provision of the ground extension minimizes the degradation of radio performance due to the weakening of the direct ground to the circuit board occupying a part of the terminal body.
According to an aspect of the present invention, such antennas are disposed inside a limited terminal, so it is advantageous to apply to a mobile terminal that is light and short.
Hereinafter, a portable terminal according to the present invention will be described in detail with reference to the drawings.

In this way, by placing the antennas arranged at a distance L2 from each other, a fading signal in which a phase of a signal introduced through another path is inverted is canceled out (diversity gain). In addition, two antennas are used to obtain aperture gain and interference rejection gain.
This is useful in the band of High Speed Downlink Packet Access (HSDPA), or Universal Mobile Telecommunications System (UMTS), which requires high data rates. In particular, 3GPP (3rd Generation Partnership Project) Release 99 maximizes the operator's network efficiency, reduces call drop, saves the output of operator node B, and releases reduced output ( release) 6 Has the advantage of being used as an output for HSDPA.
In addition, it is required to implement a reception (RX) diversity function for the High Speed Physical Downlink Shared Channel (HS-PDSCH) and the High Speed Shared Control Channel (HS-SCCH), and supports HSDPA 7.2Mbps. The handset also complies with the recommendations of 3GPP Release 6, which recommends implementing equalizers to implement high-performance receivers.
