Abstract
The utility model relates to an automobile-used two unification antennas, it contains at least: a housing; a Digital Audio Broadcasting (DAB) antenna disposed in the housing; and a Global Positioning System (GPS) antenna disposed in the housing. Through the utility model discloses an automobile-used two unification antennas designs two kinds of antenna frequency channels in a restriction space, but the inner space of make full use of casing to can realize dual signal reception's effect, with reduce manufacturing cost, promote whole pleasing to the eye and practical value.
Description
Technical field
The utility model relates to a kind of automobile-used two-in-one antenna; Be particularly related to a kind of with a digital audio broadcasting (Digital Audio Broadcasting; DAB) (Global Positioning System, GPS) antenna is integrated in the automobile-used two-in-one antenna in the housing simultaneously for an antenna and a global positioning system.
Background technology
(Digital Audio Broadcasting, DAB) (Global Positioning System, GPS) antenna is all antenna common on the general automobile for antenna and global positioning system in digital audio broadcasting.
As if DAB utilizes satellite to transmit DAB, and it is very wide that its signal is contained face, as long as all can receive signal Anywhere on the face of land, it is different therefore only utilizing ground reflector to send audio frequency with traditional broadcast.DAB is the third generation broadcasting after AM, FM case of conventional analog broadcast; Except possessing the noise resistance that digital data transmission is arranged, anti-interference, anti-radio wave propagation decline etc. numerous advantages; The service of CD stereo sound quality and digital signal more can be provided; And do not receive the multi-path interference effect within the specific limits, to guarantee fixing receiving terminal, to carry the high quality audio of receiving terminal and mobile receiving terminal.
On the other hand, GPS has been widely used in the middle of the life at present, many aspects such as for example vehicles navigation, vehicle anti-theft, engineering construction, and GPS has advantage: (1) round-the-clock use does not receive any weather effect; (2) global coverage rate is up to 98%; (3) three-dimensional fixed point constant speed timing high accuracy; (4) fast save time,, high efficiency; (5) be widely used, multi-functional; (6) removable location.
Yet in the prior art, DAB antenna and gps antenna are all indivedual independently being installed on the automobile, not only need take more installing space, because two kinds of antennas are all respectively and are made, therefore make manufacturing cost higher again.
The utility model content
The main purpose of the utility model is, a kind of automobile-used two-in-one antenna is provided, and through a DAB antenna and a gps antenna are integrated in the housing, and then reduce volume and takes up room, and can reduce manufacturing cost, to promote practical value.
For reaching above-mentioned purpose, the utility model provides a kind of automobile-used two-in-one antenna, and it comprises at least: a housing; (Digital Audio Broadcasting, DAB) antenna are arranged in this housing in one digital audio broadcasting; (Global Positioning System, GPS) antenna is arranged in the housing to reach a global positioning system.
By technique scheme, the utility model contains following advantage:
1. the utility model is through being integrated in DAB antenna and gps antenna in one housing, and then reduces volume and take up room, and can reduce manufacturing cost, to promote practical value.
2. the utility model is through being integrated in DAB antenna and gps antenna in one housing, with the effect that realizes that dual signal receives.
3. the utility model is integrated in DAB antenna and gps antenna in the one fin-shaped housing, increases overall appearance, and has preferable antenna protection effect.
4. because after the utility model was integrated in a fin-shaped housing with DAB antenna and gps antenna, the combination of antennas of these two kinds of frequency ranges can not interfere with each other, and therefore the utlity model has good signal reception.
Above-mentioned explanation only is the general introduction of the utility model technical scheme, in order more to know the technological means of understanding the utility model, and can implement according to the content of specification, below with the preferred embodiment of the utility model and conjunction with figs. specify as after.

Embodiment
For further setting forth the utility model is to reach technological means and the effect that predetermined utility model purpose is taked, below in conjunction with accompanying drawing and preferred embodiment, to the embodiment of the utility model specify as after.
, be the cross-section illustration of the automobile-used two-in-one antenna of this preferred embodiment of the utility model please with reference to as shown in Figure 1.As shown in the figure, this automobile-used two-in-one antenna 1 comprises a housing 100, (Digital Audio Broadcasting, DAB) (Global Positioning System, GPS) antenna 120 for an antenna 110 and a global positioning system in a digital audio broadcasting.Wherein, this DAB antenna 110 and this gps antenna 120 all are arranged in this housing 100.In the utility model; DAB antenna 110 for example is a satellite broadcasting (Xpress Music; XM) antenna, it is provided by U.S. XM Satellite Radio Inc., and the fixing high-quality satellite digital broadcasting program of receiving terminal to mobile receiving terminals such as automobile and household etc. can be provided.In addition, gps antenna 120 is made by the material of pottery, the size that therefore can significantly dwindle antenna.
In the utility model preferred embodiment, this housing 100 is a kind of fin-shaped housings, and that its advantage includes is handsome in appearance, length is short, windage is less and the antenna protection effect is preferable.This housing 100 is made up of a base 101 and 102 of protective covers, and this base 101 is paid mode with this protective cover 102 with the screw lock and interosculated.Yet when practical application, base 101 more can engage mode or welding manner with protective cover 102 and interosculate, and therefore has bigger manufacturing elasticity.In addition, DAB antenna 110 and gps antenna 120 are fixed on the base 101, and protective cover 102 combines with base 101 again, and DAB antenna 110 and gps antenna 120 are covered within this housing 100, reaches the effect of protection.
Moreover; As shown in Figure 1 equally; DAB antenna 110 and this gps antenna 120 respectively with two printed circuit board (PCB) (Printed Circuit Board independently; PCB) 130a, 130b combine, and these two PCB 130a, 130b can independently handle for the signal of these two kinds of antennas respectively, and carry out the integration and the transmission of signal.In addition, DAB antenna 110 and gps antenna 120 are connected with a terminating machine (not shown) by coaxial cable 140 (only showing among the figure) respectively, to utilize coaxial cable 140 aerial signal is sent in the terminating machine, and aerial signal is changed and used.
