Embodiment
Fig. 1 illustrates the broad-band antenna according to some embodiments of the present invention.
Broad-band antenna 10 is arranged to two frequency bands 12,13 of handling in the radio communications system.Yet identical principle also can be applied to three or more frequency band or radio standard.Broad-band antenna 10 shown in Figure 1 comprises row 101.These row 101 comprise antenna element 1011.Though from the reason of simplifying, example antenna shown in Figure 1 only has row and an antenna element, those skilled in the art is understood that the more than antenna element that the present invention also is listed as and is included in every row more than works.
Broad-band antenna 10 comprises shell 11.Shell 11 comprises antenna element 1011, first and second phase shifter 1012,1013 and the duplexers 1014.
Broad-band antenna 10 also comprises first phase shifter 1012 and second phase shifter 1013 that is arranged to phase shift second frequency band 13 that is arranged to phase shift first frequency band 12.
And broad-band antenna 10 comprises the duplexer 1014 of first and second frequency bands that are arranged to multiplexing phase shift.Duplexer 1014 comprises 10142 and outputs 10143 of first input, 10141, second input; Wherein first phase shifter 1012 is coupled to first input 10141; Second phase shifter 1013 is coupled to second input 10142, and antenna element 1011 is coupled to this output 10143.
Fig. 2 illustrates the broad-band antenna 10 according to some embodiments of the present invention.Particularly, Fig. 2 illustrates the example embodiment about the solution of supporting broad-band antenna 10 two frequency bands, that comprise four row 101,102,103,104.In an illustrated embodiment, first frequency band 12 is the TD-LTE frequency bands on 2.6GHz, and second frequency band 13 is the TD-SCDMA frequency bands on 1.9-2.0GHz.Yet any combination of frequency band and/or radio standard is possible, for example
-GSM is as radio standard, and two frequency bands, and frequency band tilts and second frequency band tilts with second high angle than low angle with first, is used to cover different cell area;
-GSM is as first radio standard, and LTE is as second radio standard, but identical radio bands; Perhaps
-GSM is as first radio standard, and LTE is as second radio standard, and two frequency bands, and frequency band tilts and second frequency band tilts with second high angle than low angle with first, is used to cover different cell area.
As stated, the present invention is not limited to four col width band antennas, and can be applicable to row and a multiple row broad-band antenna.
As under the situation of example shown in Figure 2, two polarization directions of typically every row 101,102,103,104 transmission, and therefore use cross-polarization antenna element 1011 or radiator.
The main element that is used for the irrelevant vertical bank of frequency band is phase shifter 1012,1013 and the duplexer 1014 between phase shifter 1012,1013 and antenna element 1011.Phase shifter 1012,1013 is for example by motor (stepping motor specifically) Electromechanical Control or complete Electronic Control.Phase shifter the 1012, the 1013rd, the part of RF feeder network, this RF feeder network terminate at antenna 10 antenna connector a side and at the opposite side of duplexer 1014/ antenna element 1011.For each polarization direction of every row 101,102,103,104 and frequency band 12,13, need a phase shifter 1012,1013.In Fig. 2,, first phase shifter 1012 and second phase shifter 1013 only are shown from simplifying reason.Yet those skilled in the art is obvious: for the situation that Fig. 2 described, because two polarization directions of frequency band 12,13, two first phase shifters 1012 and two second phase shifters 1013 are essential.In some cases, identical phase shift can be used for two polarization directions, and only needs one first phase shifter and one second phase shifter in this case.
From simplifying reason, in Fig. 2, omitted duplexer input 10141,10142 and exported 10143.
For every row 101,102,103,104 each polarization direction, need a duplexer 1014 with antenna element 1011/ antenna element crowd 1011 (all antenna elements in this group are used about the identical RF signal of amplitude and phase place and presented).
According to some embodiments of the present invention, the phase shifter 1012,1013 of frequency band of a Motor Control 12,13.
According to a further embodiment of the invention, therefore the phase shifter 1012,1013 of a polarization direction of frequency band of a Motor Control 12,13 also realizes the inclination of the polarization irrelevant of every frequency band.
According to some embodiments of the present invention, duplexer 1014 is implemented as the printed circuit on the antenna printed substrate (PWB), so that do not need outside duplexer and will optimize antenna volume and/or weight.
Fig. 3 illustrates the radio base station system 30 that comprises according to broad-band antenna 10 of the present invention.
The present invention proposes the irrelevant tilt adjustments of the frequency band of at least two frequency bands of permission or radio standard and therefore be implemented in compacter position planning in mast/tower bar place and chamber still less.
Particularly, if broad-band antenna is supported two different radio electric standards on two different frequency bands, then the present invention allows the first radio standard A obtaining bigger covering, and the second radio standard B that tilts is to be used for capacity optimization.
Though illustrate and described embodiments of the invention and application above, those skilled in the art should be understood that (except above mentioned) more modification is possible under the situation that does not depart from inventive concept described herein.Therefore, invention is unrestricted except the spirit that is subject to accompanying claims.Therefore, being intended to preceding detailed description should be regarded as illustrative and nonrestrictive.
