Accompanying drawing is intended to each embodiment illustrating and explaining the present invention, wherein:
Fig. 1 illustrates the traditional antenna systems with the passive element array being connected to RRU.
Fig. 2 illustrates the first embodiment of antenna module of the present invention.
Fig. 3 illustrates a part for the second embodiment of antenna module of the present invention.

Detailed description of the invention
As it has been described above, along with active antenna is incorporated into wireless communication system, it is necessary to this antenna is taked the anti-guarantor's measure of appropriate environment.
Therefore, the present invention relates to a kind of integrated antenna assemblies, described integrated antenna assemblies includes passive antenna sections and active antenna signal processing.Described passive antenna sections includes at least one antenna element (but being often for controlling the antenna element arrays of antenna beam in cellular communication system), for receiving/send wireless communication signals, described active antenna signal processing includes one or more signal processing unit or other are for processing the active parts of wireless communication signals.These two parts are intercomed mutually by one or more communication interfaces (such as communication cable etc.).Should be understood that the processing unit in this specification should have more to explain widely, it is possible to comprise digital signal processor (DSP), power amplifier, AD or D/A converter etc..
Antenna part and array signal processing part are connected with each other by the inter panel C between described antenna part and described array signal processing part, and described antenna part and described array signal processing are partially isolate by described cover plate.It should be noted that inter panel C can include suitable connected mode/interface, be used for transmitting the antenna element in described antenna part and described array signal processing part and the signal between signal processing unit.
And, antenna module farther includes the first pad G1 and the second pad G2, for encapsulated antenna assembly with water proof and dust proof.First pad G1 acts on the first direction D1 on inter panel C, and the second pad G2 acts on the second direction D2 on inter panel C, and wherein second direction D2 is substantially contrary with first direction D1.
Fig. 2 illustrates an embodiment of antenna module of the present invention.Integrated antenna assemblies in Fig. 2 is such as shown in cross section.The first half is array signal processing part, and the latter half is antenna part.As it can be seen, inter panel C is between upper and lower two parts.Described inter panel C and described upper and lower two parts can be interconnected by suitable fixed form, such as bolt or screw or rivet or binding agent.Fig. 2 also describes the main radiation direction of antenna.
In order to seal integrated antenna assemblies, the first pad G1 and the second pad G2 lays respectively in the first groove Gr1 and the second groove Gr2.First pad G1 acts on the first direction D1 on inter panel C, and the second pad G2 act on inter panel C with first direction D1 opposite second direction D2.Under this situation, as an embodiment, act on the offside of described elongated, smooth inter panel C.
It thus provides a kind of water proof and dust proof sealing member because the first pad G1 to the active force of inter panel C by the second pad G2 force balance to inter panel C, promote to combine closely.When inter panel C is made up of the flexible material of stress (such as flake aluminum), tightr in conjunction with meeting.
Pad G1 and G2 is made up of compressible material, such as silicone rubber or any suitable material having compression seal performance.Need it is further noted that pad G1 and G2 extends along respective circumference in the first groove Gr1 and the second groove Gr2, to reach better excellent sealing.
Therefore, this invention can be integrated by antenna and wireless processing unit (such as RRU), and antenna provides water proof and dust proof sealing member, meets the requirement of environmental protection standard needed for such antenna.
Fig. 3 illustrates the sectional view of a part for another embodiment of antenna module of the present invention.Having been mentioned above, being integrated with source circuit in antenna module needs to increase suitable cooling device.One obvious and reasonable price solution of effect is to use aluminum thermal fin HS.But, the fin HS that disadvantage is that use large-size of the program could obtain significant cooling effect.When time larger in size, between fin HS and the other parts of antenna module, occur the risk in gap, thus breakseal effect.
Embodiment in Fig. 3 includes an aluminum thermal fin HS (only shown partially), and described fin has one or more cooling flange (not shown).Fin HS also serves as the cover plate of array signal processing part in the present embodiment.Antenna module in Fig. 3 farther includes (plastics) antenna house R, is used for protecting antenna part.In the preferred embodiment, the first groove Gr1 is arranged in fin HS, and the second groove Gr2 is positioned at antenna house R.Additionally, the first groove Gr1 is in the internal extension of connecting device (this kind of situation is bolt), and the second groove Gr2 is in the outside extension of described connecting device.That is, two groove Gr1 and Gr2 extend at the not ipsilateral of connecting device, and this specific embodiment has been demonstrated have very good sealing property.Fig. 4 illustrates above-mentioned antenna module.Dotted line respectively illustrates the first groove Gr1 and the second groove Gr2.It should be noted that two groove Gr1 and Gr2 extended distance respectively d1 and d2 relative to the edge of antenna module.
Antenna module is preferably used as the antenna for base station in cellular radio Communication system, therefore the radio frequency suitable in this system.This system includes global system for mobile communications, Universal Mobile Telecommunications System, long evolving system or advanced long-term evolution system.But, the present invention is not limited to above-described embodiment, but all embodiments relating to simultaneously and comprising accompanying independent claim scope.
What fin used in antennas further aspect is that its weight.It is known that antenna module is more light more good.Inventor have been carried out surface area that fin covers can surface area than inter panel C little, to alleviate weight.Still can realize the cooling of active device.The shortcoming of this solution is in that the long-pending asymmetric introducing of different surfaces is further such that the linear sealing of such sky complicates.This invention proves to use the sealing device in the application can provide gratifying sealing effectiveness and reduce the quantity of fixture in testing, this also means that, manufactures antenna module of the present invention and can reduce production time and cost.But, use counter force of the present invention to have an advantage that, small heat dissipating plate is more little, and the skew between two pad G1 and G2 is more big.
