Abstract
The invention provides a double-antenna structure. The double-antenna structure is characterized by comprising a first antenna, a conductive separator and a second antenna, wherein the first antenna and the second antenna are arranged on two opposite surfaces of the conductive separator, the first antenna is provided with a grounding part and a signal receiving and transmitting part, the second antenna is provided with a grounding part and a signal receiving and transmitting part, and the signal receiving and transmitting part of the first antenna and the signal receiving and transmitting part of the second antenna are arranged on the opposite sides of the conductive separator in two different directions. By means of the double-antenna structure, the isolation degree between the two antennas of the double-antenna structure is greatly increased.
Description
[technical field]
The present invention relates to a kind of double-antenna structure.
[background technology]
The product of tool WiFi MIMO (802.11n) function that gets more and more on the market at present, usually two antennas are at least needed to design, if small product size does not generally have too large problem greatly, by the two edges of product design at product, because of enough apart from large isolation, nature antenna between influence each other and interference little, do not have what problem.
But when running into the product of certain elongated strip, two antennas when designing because the distance between antenna is short, the interference phenomenon of two antennas just can produce, namely so-called isolation (Isolation) is inadequate, now WiFi transmitting-receiving usefulness can be deteriorated, such as Laptop dongle network interface card, or television rod, WiFi television receiver, high in the clouds WiFi receives and dispatches rod ... Deng the product of strip.In addition for the product of strip, time as the frequency of two antennas, such as, be all 2.4GHz, mutual disturbing effect certainly will be had, cause WiFi to receive bad.
In view of this, the invention provides a kind of double-antenna structure, it can strengthen isolation between antennae.
[summary of the invention]
Main purpose of the present invention is to provide a kind of double-antenna structure, and it can strengthen isolation between antennae widely.
For reaching above-mentioned purpose, the invention provides a kind of double-antenna structure, it is characterized in that, comprise: one first antenna, one conduction separator, and one second antenna, two apparent surfaces of described conduction separator are located at by described first antenna and described second antenna, described first antenna has a grounding parts and a signal transmitting and receiving portion, described second antenna has a grounding parts and a signal transmitting and receiving portion, and the signal transmitting and receiving portion of described first antenna and the signal transmitting and receiving portion of described second antenna are located at the opposite side of two different directions of described conduction separator.
Preferably, the signal transmitting and receiving portion of described first antenna and the signal transmitting and receiving portion of described second antenna are located at the left and right sides in the upper and lower surface direction of described conduction separator.
Preferably, the signal transmitting and receiving portion of described first antenna and the signal transmitting and receiving portion of described second antenna are all in L-type.
Preferably, the grounding parts of described first antenna and all rectangular sheet of grounding parts of described second antenna.
Preferably, described conduction separator is pcb board, FPCB plate or metallic plate.
Compared with prior art, double-antenna structure of the present invention is by establishing conduction separator to increase isolation between two antennas between described first antenna and described second antenna, the signal transmitting and receiving portion of described first antenna and described second antenna is arranged at the opposite side of two different directions of conduction separator in addition, thus the radiation direction of two antennas can be staggered avoid interference mutually and increase isolation, moreover, the rectangular sheet of grounding parts of the present invention, therefore contact area also contributes to comparatively greatly the increase of the isolation of two antennas, there is this visible, design by said structure, isolation between two antennas of double-antenna structure of the present invention is greatly enhanced really.
[accompanying drawing explanation]
Fig. 1 is the decomposing schematic representation of a kind of double-antenna structure one of the present invention preferred embodiment.
Fig. 2 is the combination schematic diagram of double-antenna structure of the present invention shown in Fig. 1.
[embodiment]
Refer to shown in Fig. 1, a kind of double-antenna structure one preferred embodiment of the present invention comprises 1, one conduction separator 2, and one second antenna 3, two apparent surfaces of described conduction separator 2 are located at by described first antenna 1 and described second antenna 3, and described first antenna 1 has a grounding parts 11, and one for the signal transmitting and receiving portion 12 of receiving and transmitting signal, described second antenna 3 has a grounding parts 31, and one for the signal transmitting and receiving portion 32 of receiving and transmitting signal.Radiation direction in order to avoid described first antenna 1 and described second antenna 3 staggers avoid interference mutually and increase isolation, the signal transmitting and receiving portion 12 of described first antenna 1 and the signal transmitting and receiving portion 32 of described second antenna 3 are located at the opposite side of two different directions of described conduction separator 2, as shown in Figure 1, be located at the left and right sides in the upper and lower surface direction of described conduction separator 2 in the present embodiment, in the present embodiment, the signal transmitting and receiving portion 12 of described first antenna and the signal transmitting and receiving portion 32 of described second antenna are all in L-type.In addition, the grounding parts 11 of described first antenna 1 and all rectangular sheet of grounding parts 31 of described second antenna, because this increasing the contact area of described two antennas 1,3, also contribute to the increase of the isolation of two antennas 1,3.
In the present invention, described conduction separator 2 can be pcb board, FPCB plate or metallic plate etc.
Double-antenna structure of the present invention can by WiFi two Antenna Design on strip product, such as Dongle/ television rod etc., when two antennas quite near time, its isolation of changeable, avoids two antenna distances too closely and mutually to disturb caused transmitting-receiving message bad.
