Abstract
Description
The present invention relates to an antenna, and more particularly, to a dual antenna for a terminal apparatus.
Generally, an antenna for a terminal device can be divided into an external antenna and an internal antenna according to a mounting position. An antenna for a terminal device forms a predetermined pattern and generates an electromotive force by radio waves, so that it can receive a signal or radiate radio waves by an electromotive force. And includes a feeder or feeding part for electrical connection and grounding between a radiating part that radiates radio waves and a substrate on which a part for signal processing is mounted when radiating radio waves.
Korean Patent Laid-Open No. 10-2010-0073144 (hereinafter referred to as "prior patent") discloses a portable terminal apparatus having a MIMO antenna. In the case of the prior art, including two antennas, two ports are connected to the two antennas, that is, two feed parts. Therefore, in the case of the prior patent, the volume occupied in the end of the portable terminal becomes large, which leads to a disadvantage of increasing the volume of the terminal device.
In addition, in recent years, with the diversification of functions of terminal apparatuses, terminal apparatuses including external antennas are increasing in the terminal apparatuses. Conventionally, an external antenna of a terminal device and a terminal device are coupled through a screw connection. However, in this case, a separate step of forming a screw hole is required, and in the case of a screw hole, a foreign matter is put in the hole. Therefore, there is a disadvantage that it becomes difficult to connect the antenna and the terminal device by the foreign matter.
Accordingly, it is an object of the present invention to provide a dual antenna for a terminal device capable of receiving signals of various frequencies while simplifying the configuration.
It is another object of the present invention to provide a dual antenna for a terminal device in which no foreign matter is formed between an antenna and a terminal device, and an antenna and a terminal device are easily combined.
The present invention provides a dual antenna for a terminal device. The dual antenna for a terminal device includes a magnetic part formed on one side of a casing of a terminal device and having a magnetism, one end of which is coupled to the magnetic part by magnetic attraction, And an antenna having a first frequency and one end thereof being coupled to the magnetic portion on the opposite side to which the magnetic portion and the built-in antenna are coupled by magnetic attraction and being detachable from the terminal device, And an external antenna having a second frequency different from the first frequency.
The magnetic portion may be coated with an electrically conductive material, and one end of the built-in antenna and one end of the external antenna may include a metal portion, and the internal antenna may be electrically connected to a feed portion formed on one side of the substrate. When the external antenna is coupled with the magnetic portion, the internal antenna, the magnetic portion, and the external antenna are located on a virtual straight line perpendicular to the substrate, and the external antenna, the magnetic portion, The built-in antenna, and the power supply unit may be electrically connected.
The dual antenna for a terminal according to the present invention can simplify the antenna structure by electrically connecting two antennas to one feeder.
In addition, in the dual antenna for a terminal device according to the present invention, since the external antenna is coupled to the terminal device by magnetic attraction, foreign matter is not formed between the antenna and the terminal device, have.
