Description

DMB antenna {Digital Multimedia Broadcasting (DMB) antenna}

The present invention relates to a DMB antenna. More particularly, the present invention relates to a DMB antenna, and more particularly, it relates to a DMB antenna in which a rotating folding attachment is provided at a lower portion of each of a plurality of cylindrical poles constituting an antenna, And more particularly, to a DMB antenna capable of providing various types of receiving support functions together with receiving function.

Portable terminals (mobile phones, navigation systems, PMPs, smart phones, tablet PCs, etc.) are mostly equipped with DMB function.

A reception antenna for smoothly watching the installed DMB is provided externally or integrally.

The receiving antenna included in the portable terminal is a monopole antenna having a helical structure in which a plurality of cylindrical poles are inserted so as to be superimposed one upon the other, .

However, in the case of a portable terminal to which an external antenna is applied, there is a problem that it is inconvenient to carry the external antenna separately,

In addition, in the case of a portable terminal to which an integral type antenna is applied, there has been a problem in providing a limitation to miniaturization of the portable terminal.

In addition, there is a problem in that it is monotonous in function that can not provide additional functions other than the DMB antenna function in common.

In recent years, techniques for solving the above-mentioned problems have been continuously proposed.

In Korean Patent Application No. 10-2004-0078004, as shown in FIG. 5, an antenna capable of receiving a satellite broadcast signal, a jack of a mobile communication terminal capable of watching a satellite broadcast, and an antenna And an antenna connecting member coupled to the antenna and detachably connected to the mobile communication terminal through the holding part while the connecting pin is fastened to the jack, .

This is because it is possible to easily attach and detach an external antenna for receiving a satellite broadcast signal to a mobile communication terminal, and when a mobile communication terminal is placed on a desk or the like and watches a satellite broadcast, It is possible to view the satellite broadcasting in a state in which the level is maintained without tilting.

In Korean Patent Application No. 10-2006-0132622, as shown in FIG. 6, a first antenna unit installed in a built-in terminal to operate in a first frequency band; And a second antenna unit connected to the first antenna unit and connected to the second antenna unit in a second frequency band different from the first frequency band, And a second antenna unit having both ends coupled to the terminal and being pulled out and inserted from the terminal in a sliding manner.

This is because the second antenna is built in the terminal during normal storage, so that a service having a shorter wavelength than that of the terrestrial DMB can be used and the antenna can be easily exposed to the outside for use in watching terrestrial DMB broadcasting, The antenna can be used as a pedestal that can be placed on a desk for outdoor use without a special cradle and the connecting portion between the second antenna unit and the terminal can be realized in a polygonal shape, And can reduce the size of the entire terminal by reducing the number of antennas for each band through a multi-band antenna.

Thus, in addition to the basic functions of the DMB antenna, several DMB antennas with additional useful functions have been proposed

However, consumers want a more advanced DMB antenna, and the technology development based on this demand is continuing.
