Embodiment Construction

[0029] Several preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. In these drawings, the same or similar elements are denoted by the same reference numerals even if they are depicted in different drawings. In the following description, detailed descriptions of known functions and structures incorporated herein have been omitted for brevity.

[0030] FIG. 2 is a block diagram illustrating an internal structure of an external antenna detection device according to an embodiment of the present invention.

[0031] Referring to FIG. 2, a first built-in antenna 200 and a second built-in antenna 202 are internal antennas embedded in a mobile terminal. As an example, it is assumed here that the mobile terminal has at least two antennas for obtaining antenna diversity when receiving broadcast signals. The first built-in antenna 200 is a dual-band antenna that transmits / receives a radio signal for a general cellul...

Abstract

An external antenna detection apparatus in a mobile terminal for receiving a satellite digital multimedia broadcasting (DMB) service. The external antenna detection apparatus includes at least one built-in antenna for receiving a gap filler signal; a detachable external antenna for receiving a satellite signal; a radio frequency (RF) module for transmitting / receiving a radio signal; an antenna connector for switching a reception path to one of a first path connected to the built-in antenna and a second path connected to the external antenna; a connector coupler for selecting the reception path according to whether the connector coupler is coupled to the antenna connector; and a baseband processor for processing a signal received through the first or second path via the RF module, monitoring a change in voltage-level signal, and detecting attachment and detachment of the external antenna according to the monitoring result.

Description

technical field [0001] The present invention generally relates to an apparatus and method for detecting an external antenna in a mobile terminal, and in particular, to an apparatus and method for detecting an external antenna in a mobile terminal supporting a Digital Multimedia Broadcasting (DMB) service. Background technique [0002] Generally, digital broadcasting technology refers to a technology that replaces traditional analog broadcasting technology to provide users with high-quality audio / video services. Such a digital broadcasting technology has been developed into a terrestrial broadcasting technology and a satellite broadcasting technology. Broadcasting signals are received via terrestrial repeaters in terrestrial broadcasting, and broadcasting signals are received via satellite repeaters in satellite broadcasting. The DMB technology is one of typical digital broadcasting technologies. The DMB technique is also classified into a terrestrial DMB technique and a sa...
