Abstract

The utility model relates to an antenna structure of a digital television, wherein, a copper tube is arranged on the exterior of the antenna cable, an antenna shell made from plastic material is arranged on the exterior of the copper tube, the other end on the opposite of the antenna apex is equipped with a connector that is electrically connected with the electronic product. The copper tube is characterized in that the antenna apex is a feed-in terminal of the antenna cable which extends to the connector and forms a structure that reduces the antenna length.

Description

The structure of digital TV antenna

Technical field

The utility model relates to a kind of structure of digital TV antenna, uses a copper pipe as antenna body frame structure, and the frequency response of required frequency band is provided, and especially partly replaces the antenna of traditional helical coil framework at low frequency.

Background technology

The application of antenna is very extensive, such as need to use the product of wireless telecommunications, the existence of antenna is nearly all arranged, and antenna concerns that wireless signal receives and launch mass very corrupt, therefore it is constructed a little difference and can cause antenna receiving-sending news quality, see also TaiWan, China patent announcement number M290618 number " miniaturization digital broadcasting antenna " novel patent, it is to interconnect by first antenna and second antenna, to reach the purpose that it shortens antenna length, but described first antenna and second antenna are all helicoidal structure, and described helicoidal structure antenna has following disappearance:

Helical antenna received signal instability: because helical antenna may cause elastic fatigue because service time is longer, length is increase and decrease to some extent naturally, and different antennae frequency response that length causes is different naturally;

The helical antenna frequency range is narrower: the structure of helical antenna is very simple and easy and cheap, but its receivable frequency range relative narrower;

The helical antenna size can't be reduced significantly: helical antenna is applicable to than low-frequency range for making it, so that its size must design is longer, can reach its purpose.

For solving above-mentioned disappearance, the structure of digital TV antenna of the present utility model is the helical antenna structure for a change, uses the integral type copper pipe instead as the antenna main structure, can effectively improve above-mentioned disappearance.

Summary of the invention

Based on the disappearance that solves the above existing skill, the utility model is the structure of digital TV antenna, its main purpose provides a copper pipe as the antenna main structure, and the antenna of non-traditional helical coil framework, the utlity model has that reception is stable, can to receive frequency range bigger, and the various advantages of dwindling antenna volume.

The applicable frequency range of structure that another purpose of the present utility model is digital TV antenna of the present utility model includes: Digital Television signal (DVBT)/hyperfrequency (UHF) (474～860MHz).

In order to achieve the above object, the structure of digital TV antenna of the present utility model, it is to be to be provided with a copper pipe in antenna cable outside, there is a plastic material described copper pipe outside to constitute antenna casing, with respect to the other end on antenna top is to be provided with one to make a connector that is electrically connected with electronic product, copper pipe is by the feed side of antenna top as the antenna cable, and described antenna cable extends to connector, has the structure of reduction antenna length with formation

The structure of digital TV antenna of the present utility model, it is to have following advantage:

1, the copper pipe antenna receiving signal is very stable: because the copper pipe antenna can be not longer because of service time, cause elastic fatigue, length is maintained fixed forever, so received signal is very stable;

2, copper pipe antenna bandwidth broad: have the copper pipe of hollow structure, but its frequency acceptance band is wide than the conventional helical antenna;

3, the copper pipe antenna length can reduce significantly: the copper pipe antenna has extremely broad frequency acceptance band, still can reach the effect more preferable than conventional helical antenna so shorten length.

For further the utility model being had more deep explanation, be by following diagram, figure number explanation and detailed description of the invention.

Fig. 2 is the diagrammatic cross-sectional side elevation of Fig. 1.

Reference numeral: 1～antenna; 11～shell; 12～copper pipe; 13～antenna cable; 14～connector.

Embodiment

Now cooperate following graphic explanation detailed structure of the present utility model, and connection relationship.

See also Fig. 1, shown in 2, side-looking schematic appearance and diagrammatic cross-sectional side elevation for the big frequency range antenna of the utility model tool, wherein the antenna cable of antenna 1 (Antenna Cable) 13 is a coaxial cable, its outside is to be provided with a copper pipe 12, there is a plastic material described copper pipe 12 outsides to constitute antenna casing 11, with respect to the other end on antenna 1 top is to be provided with one to make a connector that is electrically connected 14 with electronic product, copper pipe 12 is by the feed side of antenna 1 top as antenna cable 13, described antenna cable 13 also extends to connector 14, have the structure of reduction antenna 1 length with formation, can avoid the various shortcoming of the antenna of traditional helical coil framework simultaneously.

The applicable frequency range of the structure of digital TV antenna of the present utility model includes: Digital Television signal (DVBT)/hyperfrequency (UHF) (474～860MHz); the utility model is not subject to the application of Digital Television signal and hyperfrequency; such as (474～860MHz) antenna frequencies is all protection range of the present utility model to drop on this applying frequency.

The above, it only is preferred embodiment of the present utility model, when can not with the scope implemented of qualification the utility model, promptly the equalization of being done according to the utility model claim generally changes and modifies, and all should still belong in the scope that the utility model patent contains.
