The present invention relates to a portable terminal having an antenna for receiving a satellite broadcast. More particularly, the present invention relates to a portable terminal having an antenna for receiving satellite broadcast, which can contribute to miniaturization as well as to improve space utilization and design freedom of the portable terminal. It relates to a portable terminal.

In general, a portable terminal has been widely used as a convenience that anyone can easily carry and use freely anywhere.

Such portable terminals have been used for wireless voice communication. However, as the functional areas are gradually diversified, portable terminals having various additional functions as well as basic voice communication functions have been developed. Portable terminals equipped with an antenna for receiving a satellite broadcast are commercially available to receive a satellite multimedia (DMB) service using satellites.

On the other hand, in the case of shaded areas that cannot receive signals directly from satellites such as building areas, subways, and tunnels, satellite repeaters called gap fillers are used to receive signals from satellites and transmit them to each terminal. In order to receive a signal transmitted from a satellite repeater, an antenna for satellite broadcast reception using a diversity technique is used.

Diversity technique is a technique that overcomes fading by receiving and properly combining several signals affected by independent fading, and transmitting through two or more independent propagation paths (ie, two or more antennas). It is a method of using a signal having the best characteristics among several received signals.

However, in the conventional portable terminal, since the second antenna 42 for implementing diversity together with the first antenna 41 is accommodated and installed inside the main body 20, the space utilization and design freedom of the main body are also provided. In addition to the deterioration of the terminal, the size of the terminal is inevitably increased, resulting in a problem that the size of the terminal is reversed.

That is, as the second antenna 42 accommodated and installed inside the main body to implement diversity together with the first antenna 41, a built-in antenna such as a planar inverted-F antenna may be applied. However, such a built-in antenna has a problem that the portion occupied by the antenna is large and difficult to manufacture small.

Accordingly, there is a problem in that space utilization and design freedom of the main body 20 are deteriorated because a predetermined space must be secured inside the main body 20 to install the built-in antenna. There has been a problem that the size is increased to counteract the miniaturization of the terminal.
