Description

Luminescent antenna of mobile communication terminal {LUMINOUS ANTENNA FOR A MOBILE COMMUNICATION TOOL}

The present invention relates to a mobile communication terminal for transmitting and receiving electromagnetic signals and to an antenna that can be used in other wireless communication, and more particularly, to a light emitting antenna for a mobile communication terminal that prevents a decrease in transmission reception capability and reduces unnecessary battery consumption.

In general, the antenna configuration of a mobile communication terminal can be divided into electrical and mechanical aspects. Among them, the electrical characteristics are physically resonant with electromagnetic waves of a frequency band corresponding to the purpose among a myriad of electromagnetic waves present in space. This is the device to convert the energy of the electromagnetic wave energy in the space E-Field and H-Field in the form of energy in the form of voltage and current. The antenna is one of the devices that greatly influence the performance index of the terminal. As consumer needs have evolved from terminals for voice communications to terminals requiring data communications and additional functions, improvements in antenna transmission and reception capabilities are required. On the other hand, as the antenna protrudes to the outside of the mobile communication terminal, technologies for providing additional accessory functions in addition to the inherent functions of the antenna are being developed. As one example of such an effort, a light emitting antenna in which the protrusion of the antenna is turned on has been proposed. Early light emitting antennas were developed as a structure that attracts the user's attention through simple light emission, and furthermore, the light emitting antenna has a function of indicating a communication state between the terminal and the base station.

However, the light emitting antenna according to the related art which can exhibit the communication state as described above has a problem of lowering the electromagnetic wave reception capability of the antenna. It is understood that the performance of the antenna is reduced because the control unit and the energy supply source of the light emitting element are in a coil portion that determines the performance of the antenna. This causes a mismatch between the antenna and the terminal output, resulting in unnecessary terminal power consumption.

1 is a cross-sectional view showing a light emitting antenna applied to a helical antenna according to the prior art.

A helical antenna refers to an antenna wound spirally with a physical resonance length of 1 / 2λ and 1 / 4λ using a conductive object. It is wound spirally using a conductive conductor, and has a ground plane and a feed line. Such a helical antenna is manufactured with a stub antenna and a retractable antenna and is applied to a mobile communication terminal.

A helical conductive coil existing inside the antenna is referred to as helix 3. The control unit 1 is present in the helix to take power for control and light emission of the light emitting element 2 from the power radiated into the space through the helix 3, which is a factor that lowers the radiated power of the antenna . In addition, there is a conductive material inside the helix 3, which causes mismatch between the output terminal of the terminal and the antenna, thereby causing unnecessary power consumption and performance degradation of the mobile communication terminal. In addition, since the controller 1 and the light emitting device 2 of the light emitting unit exist inside the helix 3 which is a core part of the antenna, the inherent characteristics of the helical antenna are changed, thereby degrading the performance of the antenna.

Accordingly, the present invention is to solve the above disadvantages, and eliminates the mutual influence between the light emitting element and the light emitting control unit and the antenna existing inside the mobile communication terminal to prevent unnecessary power consumption due to the mismatch of the antenna and It is an object of the present invention to provide a light emitting antenna for a mobile communication and a wireless device that can prevent transmission and reception deterioration.

The present invention for realizing the above object is an antenna of a mobile communication terminal having a helix, a dielectric bobbin for holding and fixing the helix, and a feed metal for feeding the helix, wherein the light emitting element and the light emitting portion under the dielectric bobbin The controller is installed, and a part of the antenna cover is recessed and coupled to the inside of the mobile communication terminal main body so that the light emitting device and the light emitting controller are not positioned inside the helix.
