Problems solved by technology

[0009] As described above, a portable terminal equipped with an antenna formed by combining a helical antenna and a monopole antenna simultaneously receives radio waves for CDMA communication and radio waves for receiving DMB broadcasting, so a wide frequency band is required, and at the same time, there is a problem that reception strength decreases
[0010] Furthermore, antennas for CDMA communication generally have strong sensitivity, so there is a problem of limiting DMB broadcast reception, that is, receiving both radio waves for CDMA communication and radio waves for DMB broadcast reception at the same time, but there is a possibility that the strength of the two radio waves is reduced. question

Abstract

The present invention relates to a portable terminal with multiple antenna, which accurately receives and transmits a broadband radio wave by comprising more than two antennas in the frequency-band and selectively connecting to the circuit board; increasing the utilization of antenna by selecting a proper antenna based on the functions of the mobile terminal; and automatically turning the antenna towards the mobile terminal when changing to a using mode, and vice versa.

Description

technical field [0001] The present invention relates to a portable terminal, in particular to a portable terminal with multiple antennas. Background technique [0002] Generally, portable terminals are wireless mobile communication equipment used by users indoors or outdoors or while moving. From the initial portable terminals that only send and receive voice, they have developed into multiple functions such as game execution, MP3 listening, Internet and TV viewing, etc. equipment. [0003] In particular, with the rapid development of mobile communication transmission speed, third-generation (3G) communication has become popular, and with the development of Digital Multimedia Broadcasting (DMB: Digital Multimedia Broadcasting) technology, existing portable terminals can listen to DMB broadcast. [0004] The existing third-generation communication technology uses a frequency of about 2GHz, and the transmission speed is in the range of 128kbps to 2Mbps. In Korea, a frequency...
