The high end antenna is extracted from the high end coaxial line (9) with the frequency of 1700MHz to 2500MHz. The low end antenna is extracted from the low end coaxial line (10) with the frequency of 800MHz to 1000MHz. The high end coaxial line, the low end coaxial line and the common coaxial line are respectively connected with the microstrip circuit, and form a conformal structure of a dual-frequency antenna.The ultra-wideband dual-frequency combiner has simple structure, can achieve 38 percent relative bandwidth, has low cost, is suitable for mass production, and can be used as the connection terminal port of the radio frequency signals of two frequency channels.
Description
Technical field
The utility model relates to antenna of mobile communication base station and radio-frequency technique field, relates in particular to super wideband dual-band dual-polarized antenna.
Background technology
In current mobile communication system, multiple standard station altogether becomes a kind of trend, granting along with 3G license, the application meeting of dual-band dual-polarized antenna is more and more general, pass through mixer, make the radiofrequency signal of two frequency ranges can be, avoided addressing again and set up again, reduced the cost of building a station from output of port or input.General mixer mostly is cavity body structure at present, though better performances, but volume is big, Heavy Weight, cost height, and external radio-frequency joint, when the inner use of antenna, to additionally increase corresponding a pair of radio-frequency joint, not only increased cost, the more important thing is narrow and small relatively antenna space Rigen originally just to fail to lay down, this shows that the mixer of existing cavity body structure can not adapt to the needs of dual-band antenna.Thereby when realizing dual-band antenna, just press for a kind of in light weight, volume is little, the new construction mixer of with low cost and function admirable.
The utility model content
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art, provide a kind of simple in structure, with low cost, be convenient to produce, and can well be conformal with dual-band dual-polarized antenna, can satisfy the ultrabroad band dual-frequency channel merger of dual-band antenna demand in the gsm system of present maximum customer volume and the 3G system.
For achieving the above object, ultrabroad band dual-frequency channel merger of the present utility model adopts microstrip line construction, it comprises: circuit board, public coaxial line, microstrip circuit, high-end coaxial line and low side coaxial line, its middle and high end coaxial line and low side coaxial line are stuck in the fluting of coaxial line soldering apparatus, high-end antenna is drawn by high-end coaxial line, and its frequency is 1700MHz-2500MHz; The low side antenna is drawn by the low side coaxial line, and its frequency is 800MHz-1000MHz; This high-end coaxial line, low side coaxial line and public coaxial line are connected with microstrip circuit, form the conformal structure of dual-band antenna.
Above-mentioned ultrabroad band dual-frequency channel merger, wherein circuit board is fixed on the Antenna baseplate.
Above-mentioned ultrabroad band dual-frequency channel merger, wherein public coaxial line, high-end coaxial line and low side coaxial line are fixed on the Antenna baseplate by the coaxial line geometrical clamp.
Above-mentioned ultrabroad band dual-frequency channel merger, the heart yearn of wherein public coaxial line, high-end coaxial line and low side coaxial line weld with microstrip circuit respectively, and crust and the welding of welded ground pad.
Advantage of the present utility model compared with the prior art is as follows:
1. because this mixer adopts microstrip structure, each parts is welded on the same circuit board, has avoided the multi-cavity body structure, make the in light weight of mixer, size is little, and function admirable is easy to processing in enormous quantities.
2. owing to adopt high-end coaxial line and low side coaxial line soldering apparatus, realized conformal with the dual-band dual-polarized antenna of 1700-2500MHz and 800MHz-1000MHz, and high-end relative bandwidth can reach 38%.
Description of drawings
Fig. 1 is a Facad structure vertical view of the present utility model.
Embodiment
With reference to Fig. 1, the utility model is made up of circuit board 1, public coaxial line 2, coaxial line geometrical clamp 3, coaxial line soldering apparatus 4, microstrip circuit 5, solder mask 6, rivet hole 7, Antenna baseplate 8, high-end coaxial line 9 and low side coaxial line 10.Wherein:
Circuit board 1 adopts the polytetrafluoroethylene double face copper, its front-side etch has microstrip circuit 5, scribble solder mask 6 and the two-sided silver that soaks on the microstrip circuit 5, be subjected to soda acid and salt air corrosion to prevent micro belt board, this circuit board is fixed on the Antenna baseplate 8 by rivet hole 7.High-end coaxial line 9 is stuck in the fluting of the coaxial line soldering apparatus 4 that is connected separately with low side coaxial line 10, draw the high-end antenna that frequency is 1700MHz-2500MHz by this high-end coaxial line 9, draw the low side antenna that frequency is 800MHz-1000MHz by this low side coaxial line 10.The public coaxial line 2 that is connected with the radio frequency cable socket is stuck in the fluting of connected coaxial line soldering apparatus 4, is used to transmit the radiofrequency signal that receives.Public coaxial line 2, high-end coaxial line 9 and low side coaxial line 10 are connected with microstrip circuit 5 respectively, and the formation low side is 1700-2500MHz, and high-end is the dual-band antenna conformal structure of 800MHz-1000MHz.Described public coaxial line 2, high-end coaxial line 9 and low side coaxial line 10, their heart yearn weld with microstrip circuit 5 respectively, and crust welds with the ground pad of the soldering apparatus 4 that is connected separately.Coaxial line geometrical clamp 3 is fixed on public coaxial line 2, high-end coaxial line 9 and low side coaxial line 10 on the Antenna baseplate 8 by the rivet hole on the geometrical clamp 7, to prevent the swing of coaxial line.
Above-mentioned mixer also can be fixed in the can by the rivet hole cartridge screw, and external radio frequency socket uses.Microstrip circuit is slightly different in such cases, only need remove coaxial line soldering apparatus 4, during use the radio frequency socket flange is fixed in outside the can with screw, and the socket core directly is welded on the microstrip circuit 5 and gets final product.
Above-mentioned execution mode only is a special case of the present utility model, does not constitute any restriction of the present utility model.Obviously can make different structure modifies according to design of the present utility model, but these are all within protection range of the present utility model.
