Antenna for mobile broadcast reception {ANTENNA FOR RECEIVING MOBILE BROADCASTING}

The present invention relates to an antenna for receiving a mobile broadcast, and more particularly, an antenna for a mobile broadcast receiving, which is convenient to carry with a terminal mounted on a vehicle and can be adjusted in various lengths and directions without being disturbed by the windshield of the vehicle. It is about.

In general, in wireless communication for transmitting and receiving information by electromagnetic waves, an antenna which directly induces electric current by electromagnetic waves or induces electromagnetic waves by electric current must be essentially included as an end element of an analog circuit.

Dipole antennas, monopole antennas, and the like are known as the structure of such antennas, but a small monopole antenna is preferred for a portable wireless communication device.

The monopole antenna is designed to have a length of 1/4 of the resonant wavelength (generally the wavelength for the center frequency of the target frequency band) due to the mirror effect of the ground plane. The lower the frequency), the larger the magnitude.

In recent years, the introduction of mobile broadcasting services has become more active. Since the first commercialization of T-DMB (Terrestrial Digital Multimedia Broadcasting) service in Korea, various services such as DVB-H (Digital Video Broadcasting-Handheld) service in Europe and MediaFLO service in North America have been commercialized. We are actively developing and commercializing our own services. Accordingly, various terminals for receiving mobile broadcasts have been developed.

The mobile broadcast reception terminal includes an antenna for receiving a broadcast signal, and generally uses a monopole antenna in a rod form. The frequency band mainly used for mobile broadcasting service is VHF (Very High Frequency) or UHF (Ultra High Frequency) band, and since the signal of this band has a relatively long wavelength, the antenna should also be large in length. By adopting an antenna, a user usually carries it separately from the terminal and combines it when receiving a mobile broadcast.

However, the removable antenna not only presupposes the user's portability, but also requires the user to be combined with the terminal at the time of use. In particular, a user watching a mobile broadcast wants to obtain a sense of viewing like watching TV at home, but the viewing feeling was not satisfactory because the shape of the terminal and the shape of the antenna do not deviate from the shape of the conventional mobile phone and its antenna. . In addition, since a single antenna is used, it is not free to adjust the antenna direction, and there is a problem in that the adjustment of the antenna is limited to improve the signal quality when watching a broadcast.

Furthermore, when installing a mobile broadcast receiving terminal in a vehicle, a terminal mount is generally used, which is pressed against the windshield of the vehicle using the crimping portion, and the screen of the terminal is seated toward the driver of the vehicle. The seat is located on the dashboard of the vehicle. As such, since the terminal is positioned adjacent to the windshield of the vehicle, there is a problem that the length adjustment and the direction adjustment of the antenna are more limited due to the windshield of the vehicle.

The present invention has been devised to solve the above problems, and the purpose of the present invention is to watch a conventional TV by adjusting the length and direction of the mobile broadcast viewers freely without being disturbed by the windshield of the vehicle. It is possible to provide an antenna for mobile broadcast reception, which can have a similar viewing feeling and is excellent in gain.

In order to achieve the above object, according to an aspect of the present invention, the first and second antenna elements of the conductive rod; A horizontal post hingedly coupled to a lower portion of each of the first and second antenna elements; An antenna is provided, one end of which can be pivotally hinged to a mobile broadcast receiving device, the other end comprising a connection assembly hinged to the horizontal post.

The first antenna element or the second antenna element may be a telescopic antenna element.

The connection assembly may comprise a helical antenna element. In addition, the first and second antenna elements are preferably electrically coupled to the mobile broadcast receiver through the helical antenna elements.

The connection assembly includes an upper holder rotatably hinged to a connector that can be coupled to the mobile broadcast receiving device, a tab formed at the other end, a coupling member vertically coupled to the horizontal post, and a coupling member of the coupling member. A vertical post pivotally hinged to the protruding end, a lower holder inserted into the vertical post and having a tab formed on an outer surface thereof, a tube fitted to the upper and lower holders, and a helical inserted into an outer surface of the tube It may include an antenna element and a ring member inserted between the vertical post and the upper holder.

The connection assembly and the first and second antenna elements are preferably arranged on the same side of the horizontal post.

At least one of the first and second antenna elements may also include a second helical antenna element thereon.

According to the antenna for mobile broadcast reception according to the present invention, the first and second connecting assemblies are rotated left and right with respect to the mobile broadcasting receiver, the horizontal posts are rotated up and down with respect to the connecting assemblies, and the horizontal posts are contracted / extended. Since the antenna element is rotated, the mobile broadcasting viewer can also enjoy the viewing experience similar to that of watching a conventional TV by variously and freely performing the length adjustment and the direction adjustment without being disturbed by the windshield of the vehicle inside the vehicle, and the gain is excellent.
