Below first with reference to figure 1, wherein schematically describe the aerial array 1 with many dipole antennas 3, wherein, only mark and draw uppermost and nethermost dipole antenna specifically and only imply the dipole antenna be in therebetween.Following dipole antenna can be related at this in principle, described dipole antenna only in plane of polarization radiation and reception or be such as configured to dual-polarization, the radiator of circular polarization or elliptical polarization.The radiator of the so-called X polarization of frequent use or dipole antenna 3, it is along two plane of polarization perpendicular to one another transmitting and receiving, wherein, these planes relative to vertical line and/or horizontal line angle ground at 45 ° directed.
Shown in Figure 1 be partly also generally called that the dipole antenna 3 of radiator is fed respectively by multichannel directional filter 7 below, described multichannel directional filter is configured to binary channels directional filter in the illustrated embodiment, because aerial array transmits and receives in two frequency bands.Also mention double frequency-band combiner 7 particularly here, wherein usually can relate to multiband combiner 7, if aerial array should run in more than two frequency bands.
Should schematically show in FIG, finally can arrange n dipole antenna, wherein n is natural number.Correspondingly arrange n double frequency-band combiner 7 and n wire 11a (for transmission band A) as n transmission line 11b (namely for transmission band B), relevant distributor network 9a or 9b is connected with corresponding duplexing combiner 7 by it.
It is such for constructing according to Fig. 1, namely, flow to radiator 3 at the first frequency band, the tranmitting frequency Tx be called for short in frequency band A by the distribution network 9a being in left side in Fig. 1, and flow to radiator in the middle frequency that is that launch or that receive of the second frequency band staggered therewith (being called for short frequency band B) by the distribution network 9b being in the right in FIG or be sent to base station from radiator.
For this reason corresponding distribution network 9, specifically utilize multiple wire 11a to be connected to the double frequency-band combiner 7 of each radiator 3 with configuring for the distribution network 9a of frequency band A.But depart from the embodiment ground illustrated, multiple radiator or the radiator group comprising multiple radiator also can be fed by each multichannel directional filter 7 (double frequency-band or multiband combiner 7).
As found out in addition by Fig. 1, corresponding distribution network 9, specifically distribution network 9a are connected with transmitting directional filter 15a by wire 13a, and described transmitting directional filter is also referred to as the duplexing combiner 15a for frequency band A.
Emission band A (Tx-A) flows to duplexing combiner 15,15a and flow to follow-up interface 15'a by wire 17'a, and the signal received by radiator 3 of frequency acceptance band A (Rx-A) provides for further process finally by duplexing combiner 15a, that is interface 15 " a and wire 17 " a.
Form the aerial array about the second frequency band B accordingly.
Such frequency band A can be such as the frequency band of GSM1800 (DCS), wherein transmits and receives frequency and is in the scope of 1710MHz to 1880MHz.There is the frequency range of 1710MHz to 1785MHz and corresponding emission band Tx-A has the frequency range of 1805MHz to 1880MHz at this frequency acceptance band Rx-A.
Second frequency band B can be such as UMTS frequency band, and it transmits in the scope of such as 1920MHz to 2170MHz.Receive frequency range Rx-B for frequency acceptance band B such as can be in the scope of 1920MHz to 1980MHz at this, and wherein emission band Tx-B is in the scope of 2110MHz to 2170MHz.
But other frequency bands arbitrary or frequency band combination can be converted and be implemented in the embodiment explained equally goodly.
By Fig. 2, now multichannel directional filter 7 is described, that is basic role mode of multiband combiner 7 (concrete double frequency-band combiner 7), and passing through and stop band attenuation DS more precisely about reference frequency f.
Combiner 7 constructs with stop band attenuation like this about passing through, make via distribution network 9a and wire 13a and 11a launch run in transmission partial-band (Tx-A) by radiator 3 and make receive run in the partial-band (Rx-A) that received by radiator by and whole frequency band B is prevented from, as in Fig. 2 this about frequency band A by solid line attenuation curve D1 described by.
On the contrary, make to transfer to the emission band (Tx-B) of radiator via distribution network 9b about frequency band B and the frequency acceptance band (Rx-B) received by radiator on the contrary does not pass through damply by wire 11b and 13b and in base station or the distribution network 9b between remote radio heads and radiator 13, whole frequency band A is made to be prevented from the contrary, as in Fig. 2, this puts by a dotted line expressed by D2.
By Fig. 3, for frequency band A describe about launch directional filter 15 that is about duplexing combiner 15 by characteristic and stopband attenuation.Equally again relative to frequency f, passing through and stop band attenuation of duplexing combiner 15 is described for the frequency band A that will transmit at this in figure 3.
Frequency band A is separated into the emission band Tx-A and frequency acceptance band Rx-A that are in each other and stagger as explained.Correspondingly, for emission band Tx-A and frequency acceptance band Rx-A these two partial frequency range by duplexing combiner 15a separately, thus interface 15'a and 15 " a relative to each other stops and isolates.It is such for being configured in this, makes emission band Tx-A (that is corresponding launch sub-band or frequency band A) from (such as remote radio heads or base station) reflector S-Tx-A and to be fed in wire 13a by the common interface 16a of duplexing combiner 15a by wire 17'a and interface 15'a and finally to flow to dipole antenna 3 by distribution network 9a and multichannel directional filter 7.On the contrary, the frequency acceptance band Rx-A received by dipole antenna 3 flows to the common interface 16a of duplexing combiner 15a by distribution network 9a and can be acted on by the stopband attenuation of duplexing combiner 15a be only a) flow to receiving branch that is receiver E-Rx-A for further process by path 17 " a (by output 15 ".
This is correspondingly illustrated by stopband attenuation curve D 11 and D12 in figure 3, and illustrates for frequency band A more precisely.
The relation that corresponding is about the second frequency band B and reflector S-Tx-B and receiver E-Rx-B, and this is describing with independent accompanying drawing.
Below with reference now to Fig. 4, wherein illustrate about passing through the overall resolving ideas with stop band attenuation relative to frequency f.
In the diagram at this frequency acceptance band Rx-A of frequency band A is marked and drawed to stopband attenuation curve D 11 (as shown in Figure 3) and marks and draws the total stopband attenuation curve D 1 about the stopband attenuation curve described in fig. 2 about total frequency band A in addition.In addition, frequency band about whole frequency band A or B is marked and drawed in the diagram and more precisely respectively about affiliated frequency acceptance band Rx-A and emission band Tx-A or Rx-B and the Tx-B that belong to same frequency band.
When considering according to stop band attenuation according to the transmitting directional filter 15 of Fig. 3 of the stopband attenuation characteristic sum of the multichannel directional filter 7 of Fig. 2, so show that wherein complete attenuation D marks and draws in the diagram with dotted line according to Fig. 4 complete attenuation feature D.
In Figure 5, be complemented at Fig. 4 to emphasize, the spilling Y of stopband attenuation requirement is drawn according to complete attenuation function D, if consider stopband attenuation feature such as the frequency acceptance band A launched in directional filter 15 (duplexing combiner 15) only should and must be in the X of region, described region adds hacures in Figure 5 and marks and draws.
In other words within the scope of this invention it is possible that realize lower or more weak stop band attenuation (isolation characteristic) in double frequency-band or multiband combiner 7 and/or in duplexing combiner 15 (in the transmission path for frequency band A and in the transmission path for frequency band B).
Draw when observing following form according to consideration of the present invention, on the left side for emission band and frequency acceptance band Tx-A and Rx-A but also illustrates when considering frequency band A about multichannel directional filter (multiband combiner 7) and for the stopband attenuation of launching directional filter (duplexing combiner 15) with pass through characteristic for transmitting and receiving frequency band Tx-B and Rx-B respectively in the table.
Mean at this:
X: the passband of frequency band A
-: the stopband of frequency band A
=: stopband within the same frequency band, produces the raising of complete attenuation thus and/or such as becomes possibility to the minimizing of the requirement of launching directional filter.
If consider passing through and stop band attenuation of the distribution network 9b for running radiator in frequency band B being used for being in the right in FIG, then draw corresponding situation.
Can be found out for frequency band A by above-mentioned form, multichannel directional filter 7 and distribution network 9a not only do not make transmitting and frequency acceptance band Tx-A and Rx-A pass through and whole frequency band B is prevented from completely in distribution network 9a side for frequency band A damply.
The distribution network 9b that marks and draws the on the right in FIG situation about the second frequency band B is determined in the secondary series of above table.Draw thus, by double frequency-band combiner 7 make whole frequency band B by the interface 7b of double frequency-band combiner 7 and distribution network 9b transmitting run and also in reception runs by and whole frequency band A is completely blocked on this transmission stroke.
So draw in the 3rd row when considering the transmitting directional filter 15a in frequency band A, the input 15'a of the transmitting directional filter 15a in frequency band A make emission band Tx-A pass through and frequency acceptance band Rx-A is stoped, and make on the contrary at the second interface 15 " the frequency acceptance band Rx-A that the upper existence of a is received by radiator, and emission band Tx-B is stoped.
But duplexing combiner, that is transmitting directional filter 15 pass through based on this and stop band attenuation constructs like this, make stopband attenuation function also effective about whole frequency band B, thus there is the summation effect of stopband attenuation function here, because frequency band B causes the stopband attenuation function for the hope of the frequency band B in the distribution network of frequency band A eventually through the stopband attenuation function of multichannel directional filter 7 and the stopband attenuation function of transmitting directional filter 15 and contributes to this.
Corresponding is passing through and situation during attenuation in the distribution network considering frequency band B on the contrary.
About stopband attenuation, as its multichannel directional filter 7 (double frequency-band combiner) and to launch in directional filter 15 (duplexing combiner) realize, should be mentioned that, in the preferred form of implementation of one, the stopband attenuation of duplexing combiner 15,15a, 15b is greater than the stopband attenuation of multiband or double frequency-band combiner 7.Stopband attenuation preferably at least 5dB, especially at least 10dB, 15dB, 20dB, 30dB, 40dB, 50dB and at least 60dB of multiband combiner 7 should be greater than at the stopband attenuation of this duplexing combiner.
Corresponding transmitting and receiving apparatus as explained can when consider following in and feature realize, described aspect and feature at least provide the advantage of other local.
Therefore advantageously, preferably with logical formal construction multiband combiner 7 and/or duplexing combiner 15m15a, 15b.
