Specific implementation mode
The invention will be further described below in conjunction with the accompanying drawings.Following embodiment is only used for clearly illustrating the present invention
Technical solution, and not intended to limit the protection scope of the present invention.
As shown in Figure 1, a kind of six tunnel micro-strip combiner of three frequency range of miniaturization high isolation of the present invention, characterized in that including
Copper ground connection is covered at the back side of substrate 1, substrate 1, and front is provided with microstripline, and the microstripline includes the filter of three frequency ranges
And combiner, the filter of three frequency ranges share an output feeder, the incoming feeder of each filter at port 1
The output port of the combiner of same frequency range is connected, the combiner of each frequency range draws 2 input ports.
Substrate 1 material selection Rogers (Rogers) 6010LM, size 60.8mm*55mm*0.635mm.Substrate 1
Front is the copper sheet microstrip structure of combiner, and the back side is ground connection copper sheet.
Wherein one 2 resonator 23 of resonator constitutes the bandpass filter that centre frequency is 1G, resonator 34 and resonance
Device 45 constitutes the bandpass filter that centre frequency is 1.8G, and it is 2.5G's that 56 resonator 67 of resonator, which constitutes centre frequency,
Bandpass filter.The exponent number of bandpass filter is second order, and the type function of bandpass filter is Chebyshev, bandpass filtering
The bandwidth of operation of device is 20MHz.
The combiner of three frequency ranges includes combiner 1, combiner 29 and combiner 3 10, is to halve
Wilkinson combiners, centre frequency are respectively 1G, 1.8G, 2.5G, and the micro-strip line length of Wilkinson combiners is four
/ mono- wavelength.Each frequency band combiner is connected on to the input terminal of the corresponding bandpass filter of centre frequency therewith, port respectively
2 12 and input port that port 3 13 is combiner 1, port 6 16 and port 7 17 are the input port of combiner 29,

As shown in Fig. 2, resonator is identical split-ring resonator, and two resonator openings are oppositely arranged, micro-
Strip length is half wavelength.Coupled modes between resonator and input and output feeder line include magnetic coupling and are electrically coupled,
For magnetic coupling, resonator should be placed at the high current density of feeder line, and for being electrically coupled, resonator should be placed on the low of feeder line
At current density.Therefore when designing bandpass filter, using harmonics restraint theory, two resonators are individually placed to defeated
Enter at the high and low current density of output feeder, makes being coupling in the harmonic frequency of passband between resonator and input and output feeder line
Coupled modes it is opposite (i.e. one is electrically coupled the other is magnetic coupling), parasitic passband will be effectively suppressed, to carry
The high isolation of combiner.Because bandpass filter is coupling in input and output feeder line both ends by resonator and constitutes, resonance
It is INDIRECT COUPLING between device and input and output feeder line, rather than be connected directly, therefore additional match circuit is not needed, to
Reduce combiner size.In the present embodiment, the size of the bandpass filter of three frequency ranges is as shown in table 1, through emulation testing
The filter effect of this size is best,
The parameters of structural dimension value of 1 filter of table
As shown in figure 3, for combiner of the present invention in 1G frequency range S parameter schematic diagrames, insertion loss is small in 1G working frequency range
In 4dB, return loss is less than -10dB, is more than 15dB with the isolation between frequency.
As shown in figure 4, being combiner of the present invention in 1.8G frequency range S parameter schematic diagrames, it is inserted into and damages in 1.8G working frequency range
Consumption is less than 5dB, and return loss is less than -10dB, is more than 20dB with the isolation between frequency.
As shown in figure 5, being combiner of the present invention in 2.5G frequency range S parameter schematic diagrames, it is inserted into and damages in 2.5G working frequency range
Consumption is less than 5dB, and return loss is less than -10dB, is more than 20dB with the isolation between frequency.
As shown in fig. 6, for the alien frequencies interport isolation S parameter schematic diagram of combiner of the present invention, between alien frequencies port every
It is more than 35dB from degree.
The present invention is to apply more 1G, for tri- frequency range of 1.8G, 2.5G, can also and so on four frequency ranges of setting,
The multipath microstrip combiner of the more multiband such as five frequency ranges, all belongs to the scope of protection of the present invention.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvements and modifications, these improvements and modifications can also be made
Also it should be regarded as protection scope of the present invention.
