Embodiment
As mentioned above, along with active antenna is incorporated into wireless communication system, need to take the anti-guarantor's measure of appropriate environment to this antenna.
Therefore, the present invention relates to a kind of integrated antenna assemblies, described integrated antenna assemblies comprises passive antenna part and active antenna signal processing.Described passive antenna partly comprises at least one antenna element (but often in cellular communication system for the antenna element arrays of control antenna wave beam), for receiving/send wireless communication signals, described active antenna signal processing comprises one or more signal processing units or other active parts for the treatment of wireless communication signals.These two parts are by one or more communication interfaces (as communication cable etc.) intercommunication mutually.Should be understood that the processing unit in this specification should have explanation more widely, can comprise digital signal processor (DSP), power amplifier, AD or DA transducer etc.
Antenna part and array signal processing part interconnect by the inter panel C between described antenna part and described array signal processing part, and described cover plate is partly isolated described antenna part and described array signal processing.It should be noted that inter panel C can comprise suitable connected mode/interface, be used for transmitting antenna element in described antenna part and described array signal processing part and the signal between signal processing unit.
And antenna module further comprises the first pad G1 and the second pad G2, is used for encapsulated antenna assembly with water proof and dust proof.The 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 roughly contrary with first direction D1.
Fig. 2 shows an embodiment of antenna module of the present invention.Integrated antenna assemblies in Fig. 2 is as shown in cross section.The first half is array signal processing part, and the latter half is antenna part.As shown in the figure, inter panel C is between upper and lower two parts.Described inter panel C and described upper and lower two parts can be connected to each other by suitable fixed form, as bolt or screw or rivet or adhesive.Fig. 2 has also described the main radiation direction of antenna.
In order to seal integrated antenna assemblies, the first pad G1 and the second pad G2 lay respectively in the first groove Gr1 and the second groove Gr2.The first pad G1 acts on the first direction D1 on inter panel C, and the second pad G2 acts on the second direction D2 contrary with first direction D1 on inter panel C.Under this situation, as an embodiment, act on the offside of described elongated, smooth inter panel C.
Therefore, provide a kind of water proof and dust proof seal because the first pad G1 to the active force of inter panel C by the force balance of the second pad G2 to inter panel C, impel and combine closely.When inter panel C is made by stressed flexible material (as flake aluminum), tightr in conjunction with meeting.
Pad G1 and G2 are made by compressible material, as silicon rubber or there is any suitable material of compression seal performance.Need further to note, pad G1 and G2 extend along circumference separately 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 (as RRU), and antenna provides water proof and dust proof seal, meets the requirement of the required environmental protection standard of such antenna.
Fig. 3 shows the sectional view of a part of another embodiment of antenna module of the present invention.Above mention, in antenna module, being integrated with source circuit need to increase suitable cooling device.The solution of successful and reasonable price is to use aluminum thermal fin HS.Yet the shortcoming of this scheme is to use the fin HS of large-size just can obtain significant cooling effect.When size is larger, between fin HS and the other parts of antenna module, occurs the risk in gap, thereby destroy sealing effectiveness.
Embodiment in Fig. 3 comprises that an aluminum thermal fin HS(only partly illustrates), described fin has one or more cooling flange (not shown).Fin HS is in the present embodiment also as array signal processing cover plate partly.Antenna module in Fig. 3 further comprises (plastics) radome R, is used for protecting antenna part.In this preferred embodiment, the first groove Gr1 is arranged in fin HS, and the second groove Gr2 is positioned at radome R.In addition, the first groove Gr1 is in the inner extension of jockey (this kind of situation is bolt), and the second groove Gr2 extends in the outside of described jockey.That is, two groove Gr1 and Gr2 extend at the not ipsilateral of jockey, and this specific embodiment has been proved to be has very good sealing property.Fig. 4 shows above-mentioned antenna module.Dotted line shows respectively the first groove Gr1 and the second groove Gr2.It should be noted that two groove Gr1 and Gr2 are respectively d1 and d2 with respect to the extended distance at the edge of antenna module.
Antenna module, preferentially as the antenna for base station in cellular radio Communication system, is therefore applicable to the radio frequency in this system.This system comprises 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 relate to simultaneously and comprise appended independent claims scope at interior all embodiment.
Fin is used in antenna is its weight on the other hand.As everyone knows, antenna module is more gently better.Inventor has realized the surface area that fin covers can be less than the surface area of inter panel C, with weight reduction.Still can realize the cooling of active device.The shortcoming of this solution is that the long-pending asymmetric introducing of different surfaces further makes such antenna seal complex.This invention in test proof use sealing device in the application that gratifying sealing effectiveness can be provided and reduce the quantity of fixture, this also means, manufactures antenna module of the present invention and can reduce production time and cost.But, use the benefit of adverse effect power of the present invention to be, small heat dissipating plate is less, and the skew between two pad G1 and G2 is larger.
