Technical field
The present invention relates to antenna equipment technical field, more particularly to the micro-strip combining inside double frequency or multifrequency antenna
Device.
Background technology
Less and less to the volume requirement of antenna with the high speed development that communication system is integrated, integrated frequency range is more next
It is more.The signal of different frequency range generally requires independent interface, but the reason for be due to equipment, technology and demand, sometimes
The signal combining input or output of two frequency ranges, this is accomplished by a kind of dual-frequency channel merger to realize.It is common double on the market at present
Frequency combiner has two kinds of cavity and micro-strip plate, although the preferable cavity combiner of optimum results is with stable performance and minimum
Insertion loss, but all metals of material therefor, and it is bulky, cost is higher.Micro-strip plate biggest advantage is volume
Small, lightweight, cost is also very low, but a disadvantage is that narrower bandwidth, and due to technology limitation, most occasions can not all expire
Foot is required.

The purpose of the present invention is exactly the processing side in order to which the one kind for solving the deficiency of prior art and providing is not only simple in structure
And micro-strip combiner reasonable in design just,.
It is a further object of the present invention to provide a kind of mounting structure of micro-strip combiner.
The present invention is to realize above-mentioned purpose using following technical solution：A kind of micro-strip combiner, it is characterised in that
It includes the low frequency branch road that the high frequency branch road that frequency range is 2300MHz-2690MHz and frequency range are 1710MHz-2170MHz, low-and high-frequency
Branch road synthesizes a combining output port.
As a further illustration of the above scheme, the high frequency branch road is correspondingly arranged on high frequency interfaces, low frequency branch road correspondence
Low frequency interface is provided with, high frequency interfaces, low frequency interface and combining output port are attached all in the form of welding with outside.
Further, the micro-strip plate is provided with least four fixing hole.
Further, micro-strip plate tow sides are all covered with green oil, with protection circuit, it is ensured that outward appearance cleaning and stability.
A kind of mounting structure of micro-strip combiner, it is characterised in that it is to be fixed on inner antenna by insulated fasteners,
Or antenna-reflected plate front or back is arranged on, there is a block size identical with micro-strip plate between its micro-strip plate and antenna-reflected plate
Epoxy plate to insulate and increase mechanical strength.
Further, when micro-strip plate is arranged on antenna-reflected plate front, metallic cavity is shielded radiation signal；If
Micro-strip plate is placed on reflecting plate reverse side and does not need metallic cavity then.
Further, the power division network plate of the antenna HF array on antenna-reflected plate passes through same with combiner high frequency branch road
Shaft cable is weldingly connected；The power division network plate of antenna low frequency array on antenna-reflected plate and combiner low frequency branch road again by
Coaxial cable is weldingly connected, and combining output port is connected with adapter lead.
The beneficial effect that the present invention can be reached using above-mentioned technical solution is：
The present invention plans cabling using in certain thickness micro-strip plate front by simulation result, forms high band and low frequency
There is a number of hole position section, non-routing region, must by setting insulated fasteners to be fixed on inner antenna or reflecting plate front
Metallic shield lid can be added to prevent radiation interference when wanting；Cost is reduced in the case where ensureing that electrical specifications can be met, is dashed forward
Certain technical barrier is broken, all by fine and smooth optimization in terms of size Control, mounting process；In addition, connectivity port is weldering
The form connect, compared to N-type hickey used in general cavity combiner, intermodulation stability is more preferable.Whole working frequency range exists
In 1710MHz-2170MHz＆2300MHz-2690MHz.

Embodiment
The technical program is explained in detail below in conjunction with specific embodiment.
As Figure 1-Figure 2, the present invention is a kind of micro-strip combiner, and it is included in the frequency range set on micro-strip plate and is
2300MHz-2690MHz high frequency branch road and frequency range is 1710MHz-2170MHz low frequency branch road, and low-and high-frequency branch road synthesizes one
Combining output port.In the present embodiment, it be certain thickness micro-strip plate front by simulation result plan cabling form height
Frequency branch road and low frequency branch road；There is a number of fixing hole non-routing region.High frequency branch road is correspondingly arranged on high frequency interfaces, low frequency
Branch road is correspondingly arranged on low frequency interface, and high frequency interfaces, low frequency interface and combining output port are all in the form of welding and outside
Be attached (the outer layer metal net of such as coaxial cable), wherein ground pad have a considerable amount of heavy tin holes be used for ensure signal with
The ground of micro-strip back is fully contacted.Micro-strip plate tow sides are all covered with green oil, with protection circuit, it is ensured that outward appearance it is clean with stably
Property.
In the present embodiment, in structure, micro-strip combiner includes metal printing brush layer 1-1, the high and low frequency circuit of electroplate
1-2 and three end soldering opening 1-3,1-4,1-5, and 6 rivet fixing hole 1-6.Fixing rivet 2-1, certain thickness dielectric layer
