Embodiment one
Fig. 1 is the structural representation of inventive antenna one embodiment, this antenna refers to the antenna that can produce multiple wave beam, such as, the first input signal and the second input signal is inputted respectively from two base station signal ports of antenna, then after the internal signal process of antenna, first input signal can export the output signal of corresponding first wave beam at the output port of antenna, second input signal can export the output signal of corresponding second wave beam at the output port of antenna, that is, this antenna creates multiple wave beam.
As shown in Figure 1, this antenna can comprise: Wave-packet shaping network 11 and multiple aerial array 12 (Fig. 1 with four aerial arrays for exemplifying), wherein, Wave-packet shaping network 11 comprises at least two base station signal port ones 3 and multiple aerial signal port one 4, and each aerial signal port one 4 connects an aerial array 12; Wherein, base station signal port one 3 refers to the port be connected with base station transceiver pusher side, for receiving the signal that base station transceiver is launched; Aerial signal port one 4 refers to the port be connected with aerial array side, for exporting the output signal of Wave-packet shaping network to aerial array 12.
Wherein, this antenna comprises at least two base station signal port ones 3, because this antenna needs to produce multiple wave beam, and the corresponding wave beam of output signal that the signal of normally each base station signal port one 3 input obtains after Wave-packet shaping network 11 processes, therefore, if produce multi-beam, usually need at least two base station signal ports.The quantity of aerial array 12 be also generally have multiple, such as, four aerial arrays, eight aerial arrays etc., and in order to ensure the isolation between each aerial array, each array spatially has certain spacing.In order to export output signal to aerial array, accordingly, for connecting the quantity of the aerial signal port one 4 of aerial array also for multiple.
Wherein, the connection of aerial signal port one 4 and aerial array 12, is commonly referred to as aerial signal port one 4 and connects antenna element in aerial array 12.Concrete, aerial array 12 is made up of multiple antenna element, and each antenna element has the radiant body for transmitting, and aerial signal port one 4 is actually the antenna element be connected in aerial array 12, is transmitted by antenna element.In addition, a corresponding wave beam jointly can be formed in order to make each aerial array, at least there is between each aerial array 12 of the present embodiment an identical polarization, and each aerial array 12 of example shown in the embodiment of the present invention refers to is also each array of same polarization.
Concrete, the signal that base station signal port one 3 sends for receiving base station transceiver, this signal refers to the signal that base station will be gone out by antenna transmission.Aerial signal port one 4, for being sent to multiple aerial array 12 by output signal; Example as shown in Figure 1, a road output signal is sent to an aerial array 12 by each aerial signal port one 4.This Wave-packet shaping network 11 is for carrying out phase adjusted and amplitude adjusted to input signal, generates the multipath output signals corresponding with multiple aerial signal port.
In the present embodiment, the output signal that Wave-packet shaping network 11 exports from aerial signal port one 4, there is predetermined amplitude, owing to being multiple aerial arrays, so alternatively have default amplitude distribution, that is, Wave-packet shaping network 11 has been adjusted to due amplitude distribution when outputing signal, such as, the signal amplitude that four aerial arrays are corresponding is distributed as 0.412:1:1:0.412.
But, the difference of the present embodiment and Wave-packet shaping network of the prior art is, the output signal that the Wave-packet shaping network 11 of the present embodiment obtains not yet reaches default PHASE DISTRIBUTION, in multipath output signals, have at least the phase place of a road output signal contrary with preset phase, and the output signal that prior art is Wave-packet shaping network reach default PHASE DISTRIBUTION.Illustrate: suppose the preset phase distribution of the output signal that four aerial arrays are corresponding should be+90 degree, 0 degree ,-90 degree ,-180 spend, namely-90 degree are differed successively, then the output signal of the Wave-packet shaping network of prior art has reached above-mentioned phase place, and the Wave-packet shaping network 11 of the present embodiment is likely-90 degree ,-180 degree ,-90 degree ,-180 degree (exemplifying in FIG), namely not yet reach preset phase, the phase place having two-way to output signal is contrary with preset phase.Wherein, above-mentioned phase place is relative value, instead of absolute value, is namely the phase value of all aerial arrays has been carried out normalization relative to the phase value of wherein some aerial arrays; The phase value mentioned in the present embodiment and follow-up embodiment is also relative phase values.
In multiple aerial arrays 12 of the present embodiment, at least comprise an anti-phase array, this anti-phase array refers to the current feed phase aerial array contrary with the current feed phase of other aerial arrays; Such as, aerial array 12a shown in Fig. 1 and aerial array 12b is exactly the contrary aerial array of two current feed phases, wherein, aerial array 12a is exactly after the phase place of the output signal of correspondence (-90 degree) has been carried out anti-phase process, obtain the phase place (+90 degree) preset, and aerial array 12b does not process to the phase place of output signal.In like manner, aerial array 12c shown in Fig. 1 and aerial array 12d is also the aerial array that two current feed phases are contrary, wherein, after the phase place (-180 degree) of the output signal of correspondence has been carried out anti-phase process by aerial array 12c, obtain the phase place (0 degree) preset, and aerial array 12d does not process to the phase place of output signal.
Through above-mentioned process, the PHASE DISTRIBUTION "+90 degree, 0 degree ,-90 degree ,-180 spend " of PHASE DISTRIBUTION that Wave-packet shaping network 11 outputs signal by aerial array "-90 degree ,-180 degree ,-90 degree ,-180 degree " conversion in order to preset.So far, the output signal at aerial array place is provided with default amplitude distribution and default PHASE DISTRIBUTION, just can sentence this amplitude and signal is launched by wave beam corresponding to phase place at aerial array, namely, shown in Fig. 1 four aerial array 12 is according to the distribution of above-mentioned predetermined amplitude and PHASE DISTRIBUTION, jointly can form a wave beam, this wave beam is corresponding with amplitude and phase place.
Below the inverter functionality at above-mentioned aerial array place is described: before the input signal receiving base station transceiver, be the current feed phase of aerial array has been carried out anti-phase setting in advance.Wherein, carry out anti-phasely method to set up more known in the field can being adopted to realize to the current feed phase of described aerial array, such as, for the aerial array of half-wave dipole subtype, the distributing point connected mode of the internal and external conductor of coaxial line and oscillator arms can be changed, thus change the current feed phase of this aerial array; The aerial array of other types also adopts common technology to carry out anti-phase setting, does not repeat them here.By carrying out above-mentioned anti-phase setting to aerial array, when after this antenna array receiver to signal, anti-phase process will be carried out to the phase place of this signal, such as change-180 degree or+180 degree, for electromagnetic wave signal, it is periodic signal, and each signal period is 360 degree, so it is identical that original signal change-180 degree or+180 are spent effect in fact.
Known by above-mentioned explanation, in the antenna of the present embodiment, be actually the part of functions of the Wave-packet shaping network of prior art to share and give aerial array, be combined by Wave-packet shaping network and aerial array, jointly carry out phase-adjusted to input signal, namely, the output signal that the Wave-packet shaping network of prior art self obtains after input signal can being regulated has preset phase and predetermined amplitude, and the output signal that the Wave-packet shaping network self in the present embodiment obtains only has predetermined amplitude, in multiple output signal, only some has preset phase (the such as phase place of certain road output signal is-90 degree in fact, and this just should export the signal of this phase place to aerial array), but the phase place of some output signal is contrary with preset phase, and (the such as phase place of certain road output signal is-90 degree, but the signal phase exporting aerial array to should be+90 degree), now, be the reversed nature by aerial array, after above-mentioned phase place being carried out anti-phase process by aerial array, obtain preset phase.
Due to a part of phase adjusting function is realized by aerial array, so the structure of Wave-packet shaping network must be simplified and connect complexity.Because if above-mentioned inverter functionality is realized by Wave-packet shaping network, then the equipment such as phase shifter, electric bridge may be needed to connect and to realize, make the number of devices in Wave-packet shaping network increase; And after the present embodiment saves part of functions, Wave-packet shaping network will save a part of equipment, so draw bail can be simplified, reduce complexity and the antenna cost of Wave-packet shaping network.About this part effect, can be described for four array antennas and eight array antennas in embodiment below, can clearly see that the structure of the Wave-packet shaping network that have employed the present embodiment scheme enormously simplify.
Embodiment two
Fig. 2 is the structural representation of another embodiment of inventive antenna, and the present embodiment lists a kind of alternate configurations of Wave-packet shaping network.
As shown in Figure 2, the Wave-packet shaping network of this antenna can comprise merit separating device 21 and regulate sub-network 22; Base station signal port one 3 is arranged in this adjustment sub-network 22, and aerial signal port one 4 is arranged on this merit separating device 21, and merit separating device 21 is connected with adjustment sub-network 22.
Wherein, regulate sub-network 22 from after base station signal port one 3 receives input signal, phase adjusted and amplitude adjusted will be carried out to this input signal, generate multichannel intermediate output signal; The quantity of this intermediate output signal is less than described multipath output signals quantity, namely the quantity of aerial signal port is less than, such as, as seen from Figure 2, the quantity of intermediate output signal is two-way (S1 (-90) and S2 (-180)), and the quantity of aerial signal port one 4 is four; Because merit separating device can make the quantity outputed signal increase, the quantity of the output signal after increase just equals the quantity of signal port, and therefore, signal is before entering merit separating device, and its quantity must be less than and outputs signal quantity.
Wherein, merit separating device 21 is after the multichannel intermediate output signal described in receiving, multichannel intermediate output signal is mainly used in be converted to described multipath output signals, and power division is carried out between this multipath output signals, multipath output signals is made to have default amplitude distribution, such as, the amplitude distribution of four tunnel output signals is 0.412:1:1:0.412.Merit separating device 21 exports described multipath output signals to described multiple aerial array 12 by aerial signal port one 4.
As shown in the above description, Wave-packet shaping network be divide into two parts by the present embodiment, namely sub-network and merit separating device is regulated, wherein, regulate sub-network 22 such as can comprise the equipment such as electric bridge, phase shifter, this adjustment sub-network 22 can adopt the frame mode of this area routine, and the equipment such as electric bridge, phase shifter also can employing mode connect, and repeats no more; This adjustment sub-network 22 can carry out phase adjusted and amplitude adjusted to the input signal of base station transceiver, this adjustment sub-network 22 is mainly used in Signal Regulation to suitable phase place, this suitable phase place refers to, after this signal is divided into multichannel by merit separating device, at aerial array place, only need the anti-phase process through aerial array just can reach preset phase.And merit separating device 21 be mainly used in by Signal Regulation to preset amplitude, make the multipath output signals exporting aerial array to have default amplitude distribution; The phase place that this merit separating device 21 no longer exchanges the intermediate output signal that knot network 22 exports regulates.
The following examples three and embodiment four are respectively for four array antennas and eight array antennas, are described the structure of the antenna of the embodiment of the present invention and principle; Wherein, merit separating device is for power splitter.It should be noted that, concrete implement in be not limited to structure as follows, such as, the quantity of aerial array also can be six, ten etc.; Merit separating device may not be power splitter and adopts other can realize the structure of merit point function; Or, regulate sub-network also can adopt other electric bridge and the combining structure etc. of phase shifter.
Embodiment three
Fig. 3 is the structural representation of an inventive antenna embodiment again, and the present embodiment is four array antennas, namely has the antenna of four aerial arrays 12.
As shown in Figure 3, this antenna comprises four aerial arrays 12.The Wave-packet shaping network of this antenna comprises adjustment sub-network 22, and the adjustment sub-network 22 of the present embodiment only have employed 90 degree of electric bridges, certainly, also can adopt other structures, such as, adopt 180 degree of electric bridges and phase shifter combinations etc. in concrete enforcement; This adjustment sub-network 22 has two base station signal port ones 3 (representing with A and B in FIG).Wave-packet shaping network also comprises two merit separating devices, such as power splitter 21a and 21b (Fig. 1 for not decile power splitter), and each merit separating device has two aerial signal port ones 4.The aerial signal port of merit separating device is connected with aerial array, is represented by the connecting line between four aerial signal port ones 4 and four aerial arrays 12 respectively with 14a, 14b, 14c and 14d.
Two aerial signal port M1 (the first output port can be called) of 90 degree of electric bridges and M2 (the second output port can be called), wherein, aerial signal port M1 connects power splitter 21a (can be called the first merit separating device), and aerial signal port M2 connects power splitter 21b (can be called the second merit separating device).Each power splitter has two aerial signal ports, and such as, two aerial signal ports (i.e. the first output port and the second output port) of power splitter 21a are connected to aerial array 12a and 12c by connecting line 14a, 14c; Two aerial signal ports (i.e. the first output port and the second output port) of power splitter 21b are connected to aerial array 12b and 12d by connecting line 14b, 14d.Wherein, as seen from Figure 3, the current feed phase of aerial array 12a and 12c is contrary, and the current feed phase of aerial array 12b and 12d is contrary; Namely, this antenna comprises two anti-phase arrays, is respectively aerial array 12a and aerial array 12d, corresponding, first output port of power splitter 21a connects one of them anti-phase array and aerial array 12a, and first output port of power splitter 21b connects another anti-phase array and aerial array 12d.
Illustrate the operation principle of the present embodiment structure below:
Suppose to input a signal from base station signal port A, this signal is after the 90 degree of electric bridges overregulated in sub-network 22 carry out phase adjusted and amplitude adjusted, export two-way intermediate output signal, namely, S1 (-90) is exported from the aerial signal port M1 of 90 degree of electric bridges, what this S1 (-90) represented is S1 signal, and the phase place of this S1 signal is-90 degree; Export S2 (-180) from the aerial signal port M2 of 90 degree of electric bridges, namely the phase place of this S2 signal is-180 degree.Each road intermediate output signal exports a merit separating device to, that is, S1 (-90) exports power splitter 21a to, and S2 (-180) exports power splitter 21b to.
Each power splitter, the two-way output signal that can phase place is divided into identical the intermediate output signal of reception, such as, S1 (-90) is after power splitter 21a, export as S1 (-90) and S3 (-90), the phase place of these two signals is identical, and the same with the phase place of the S11 (-90) originally inputted be all-90 to spend; S2 (-180) is after power splitter 21b, and export as S2 (-180) and S4 (-180), equally, the phase place of output signal is identical, is all-180 degree.But power splitter changes signal amplitude and distributes, and makes to output signal and has default amplitude distribution; Shown in Figure 3, the amplitude distribution outputed signal from four tunnels that two power splitter 21a and 21b export has become default amplitude distribution value, i.e. 0.412:1:1:0.412.
Four tunnels output signal S1 (-90) that two above-mentioned power splitters export, S2 (-180), S3 (-90) and S4 (-180), export four aerial arrays to respectively by connecting line 14a, 14b, 14c and 14d.As shown in Figure 3, the current feed phase of aerial array 12a and 12c is contrary, and aerial array 12a is converted to S1 (+90) after carrying out anti-phase process to S1 (-90).In like manner, the current feed phase of aerial array 12b and 12d is contrary, and aerial array 12d is converted to S4 (0) after carrying out anti-phase process to S4 (-180).
Shown in Figure 3, through above-mentioned process, the signal at aerial array place is provided with default PHASE DISTRIBUTION and default amplitude distribution, can form corresponding wave beam and launched by signal at aerial array place.
In addition, two base station signal ports of 90 degree of electric bridges of the present embodiment have larger isolation; Further, power splitter can regulate the amplitude that each road outputs signal according to actual needs flexibly; If from port B input signal, this antenna to the processing procedure of signal and said process similar, repeat no more.In addition, before illustrate, 90 degree of electric bridges in Fig. 3 and not decile power splitter also can adopt other structures with identical functions to substitute.
Can see by shown in above-mentioned explanation and Fig. 3, Wave-packet shaping network in the present embodiment in fact only employs 90 degree of electric bridges and two power splitters, just achieve the amplitude preset and the phase place (aerial array place assists and done an anti-phase process) at aerial array place, compared with prior art, prior art needs employing six 90 degree of electric bridges and four phase shifters usually, the amplitude preset and the phase place at aerial array place could be realized, therefore, clearly, the present embodiment enormously simplify the structure of Wave-packet shaping network, reduce the devices interconnect complexity of network internal, accordingly, also simplify the structure of antenna, reduce antenna cost.
