Description

Antenna of broadcasting signal receiver and method of manufacturing the same {Antenna of Broadcasting signal receiver and method for manufacturing the same}

The present invention relates to an antenna of a broadcast signal receiver and a method of manufacturing the same.

Portable terminals, such as mobile phones, which have a built-in broadcast signal receiver and receive a broadcast signal of a predetermined frequency, have become popular.

The broadcast signal received by the broadcast signal receiver embedded in the portable terminal mainly uses frequencies in a VHF (Very High Frequency) band and a UHF (Ultra High Frequency) band.

For example, KSDMB (KOSDAK-Digital Multimedia Broadcasting) uses 174-210 MHz, which is a VHF band-III band. DVB-T / H (Digital Video Broadcasting-Terrestrial / Handhelds) uses 170 to 230 MHz of the VHF band-III band, 470 to 8620 MHz of the UHF band, and 1452 to 1492 MHz of the L-band. In addition, ISDB-T (Integrated Services Digital Broadcasting Terrestrial) uses 470-770 MHz.

The broadcast signal receiver receiving the broadcast signal receives the broadcast signal by using an antenna having a length of 1/2 or a quarter of a wavelength of the broadcast signal.

When the antenna of the broadcast signal receiver is embedded in the portable terminal, the size of the portable terminal increases due to a large amount of space.

Therefore, many portable terminals do not have a built-in antenna of the broadcast signal receiver, but separately provide an antenna of the broadcast signal receiver as an accessory. When the user receives the broadcast signal through the broadcast signal receiver, the user mounts an accessory-type antenna on the portable terminal to receive the broadcast signal.

However, the provision of the accessory-type antenna is a user's inconvenience in that the user must carry the accessory-type antenna separately from the portable terminal and mount the antenna on the portable terminal every time a broadcast signal is received.

Therefore, an object of the present invention is to provide an antenna of a broadcast signal receiver provided in a portable terminal and a manufacturing method thereof without changing the size of the portable terminal in which the broadcast signal receiver is embedded.

The present invention also provides an antenna of a broadcast signal receiver for receiving a broadcast signal by attaching an antenna of a broadcast signal receiver to a front surface of a display panel of a portable terminal, and a method of manufacturing the same.
