Abstract
The invention relates to a multiband antenna, which comprises a plane base plate, a first antenna body, a second antenna body, a third antenna body and a plurality of isolation grooves, wherein the first antenna body is arranged on the plane base plate, and the isolation grooves are positioned among the three antenna bodies and are used for mutually isolating the three antenna bodies. The multiband antenna disclosed by the invention has the advantages that a plurality of antenna bodies are mutually isolated through the effect of the isolation grooves, and the interference of each antenna body is effectively reduced.
Description
Technical field
The present invention relates to a kind of antenna with multiple operation frequency ranges.
Background technology
At present, various electronic installations, for example mobile phone is very universal, along with the continuous increase of people's demand, support the mobile phone of multi-card multi-standby to occur, same mobile phone can use multiple Mobile phone cards with different frequency bands simultaneously, for example, can use the Mobile phone card of mobile and UNICOM simultaneously, and its work that is independent of each other.
But, because the frequency band that different Mobile phone cards uses is different, therefore need in mobile phone, increase the antenna body of respective numbers, or thereby the frequency range of antenna is expanded and covers needed multiple frequency band, but, along with the increase of antenna body number, the interference between antenna body also can be more and more serious, often affects working independently of each antenna body.
In view of this, be necessary to provide a kind of antenna, to address the above problem.
Summary of the invention
The invention provides a kind of multiband aerial, this antenna comprises at least two antenna bodies that are operated in different operating frequency range, and the isolation of each antenna body is very large, has effectively reduced the interference of each antenna body.
A kind of multiband aerial, comprises planar substrates, is positioned at the first antenna body, the second antenna body, third antenna body and some isolation channels of planar substrates upper surface; Wherein, these some isolation channels are between these three antenna bodies, for these three antenna bodies are isolated mutually.
Multiband aerial of the present invention, by the effect of isolation channel, isolates the plurality of antenna body, has effectively reduced the interference of each antenna body.

Embodiment
Referring to Fig. 1, is the structural representation of multiband aerial 1 of the present invention.This multiband aerial 1 comprises planar substrates 10, is positioned at the first antenna body A1 of planar substrates 10 upper surfaces, the second antenna body A2, third antenna body A3 and some isolation channel S.These some isolation channel S are between these three antenna bodies, for these three antenna bodies are isolated mutually.
As shown in Figure 1, wherein, this planar substrates 10 is roughly a rectangle, and this first antenna body A1, the second antenna body A2 and third antenna body A3 lay respectively at the wherein position on three summits near this planar substrates 10.Between this first antenna body A1 and the second antenna body A2, there are two symmetrical isolation channel S, between the first antenna body A1 and third antenna body A3, there is an isolation channel S.Further, be the electric current of balanced each antenna body, on this close position of this planar substrates another side in the isolation channel S symmetry between this first antenna body A1 and third antenna body A3, also comprise an isolation channel S.Wherein, these four isolation channel S are L shaped structure, and the both sides of its L shaped structure are all parallel with wherein two limits of planar substrates 10.
In the present embodiment, these three antenna bodies are operated in two different working frequency range, wherein this first, second antenna body A1 is Wimax (Worldwide Interoperability for Microwave Access, worldwide interoperability for microwave access) the slotted eye type antenna of frequency range, be operated in Wimax frequency range; Third antenna body is WiFi (Wireless Fidelity, Wireless Fidelity) frequency range PIFA type (Planar Inverted-F Antenna, inverted-F) antenna, is operated in WiFi frequency range.In other embodiments, this first antenna body A1, the second antenna body A2, third antenna body A3 can be slotted eye type or the PIFA type antenna of other frequency ranges, are not limited to Wimax band antenna, WiFi band antenna.
In the present embodiment, on this planar substrates 10 to should first day line body A1, the second antenna body A2 and the region of third antenna body A3 on be also respectively arranged with corresponding antenna substrate B1, B2 and B3, these three antenna substrate B 1, B2 and B3 be for carrying respectively this first antenna body A1, the second antenna body A2 and third antenna body A3, and have and this first antenna body A1, the second antenna body A2 and the roughly the same shape of third antenna body A3.
In the present invention, by the isolation channel S of some is set, effectively reduce the interference between each antenna body, made multiband aerial 1 of the present invention can effectively be operated in multiple frequency ranges.
