- Phased array antennas are known, for example, from mobile communications technology.
- mobile antennas which consist of one or more juxtaposed columns, in each of which a plurality of superposed radiator or subgroups of radiators are arranged.
- the emitters may be simply polarized or dual polarized emitters.
- the antennas can be formed as mono-band, dual-band or as MuIti band antennas, which comprise emitters that transmit and receive in multiple frequencies or frequency ranges (frequency bands) can.
- the same frequencies are used again at certain intervals. Therefore, the range of a base station, whereby a so-called mobile radio cell is defined to be limited, so that the cells of the radio system do not interfere with each other, so that interference is avoided.
- phase shifters namely phase shifter systems
- phase shifters are preferably used in order to control the individual radiators with different phase angles, whereby a different downtilt angle can be set by electrical means.
- an odd number of radiators or subgroups of radiators can be controlled via such a simple or a multiple phase shifter, wherein preferably a middle radiator or a central radiator group without phase shift is fed directly.
- a differential phase shifter two emitters or emitter groups with different phase shifts can be triggered at the outputs thereof.
- array antennas which comprise at least one radiator or a radiator group, which are operated without phase shift
- group antennas into consideration which include an even number of radiators or radiator groups and / or have no radiator group, which is operated without phase shift.
- WO 03/019723 A1 describes an adjustable antenna feed network with a phase shift device, which is built, that the same phase differences can be generated at the leading to the radiators terminals by a displaceable dielectric.
- WO 02/35651 A1 also describes the use of phase shifters in which a dielectric is displaced in a stripline.
- the sliding path is always the same.
- the effective dielectric constants are different, it is possible to realize phase shifts at the radiator terminals which each have the same phase differences from one another. As a result, a substantially straight wavefront with different down-tilt angle can be generated.
- phase shifter elements which can be used with the same aim as explained above are basically also known from WO 96/37922 A1 as known.
- an antenna arrangement for lowering a down-tilt angle or also for setting the emission direction of the main lobe in the azimuth direction can also be taken as known from US 2005/0219133 A1.
- This pre-publication initially describes an antenna arrangement having a phase shifter assembly using differential phase shifters, the outputs of a first phase shifter arrangement being connected to the inputs of a respective second phase shifter assembly for driving the radiator elements thereover.

- Tolerances of +/- 5% can be accepted.
- the situation may occur that, for example, the first side lobe above the main radiation direction with increasing lowering of
- Cover area act as a disturber. Thus, a low sidelobe level would be desirable.
- the antenna gain should be as high as possible in order to effectively guide the available transmission power to the desired coverage area.
- a high antenna gain means a high concentration of energy.
- the optimization of the antenna gain is often accompanied by an increase in sidelobe level.
- the object of the present invention is therefore to provide an improved method for operating a phased array antenna and an improved phased array antenna itself, in which the first side lobe above or adjacent to the main lobe especially at large beam reduction (large down-tilt angle ) and / or large beam swivel has the lowest possible level (to suppress interference) and / or at low beam drop (ie, in a large cell expansion and -Eusleuchtung) or at a low beam swing generally has the highest possible antenna gain.

- FIG. 2a which comprises three part-circular line sections 11 concentrically arranged about a center point 9, generally so-called stripline sections IIa.
- a feed line 13 leads to the central feed point 9 of the tapping element 15, wherein the feed point 9 is provided in the region of the pivot axis 17 of the tapping element 15.
- the pointer-shaped tapping element 15 can be adjusted about the pivot axis 17 over the part-circular, concentrically arranged line sections 11 away.
- the feed signal is then transmitted to the respective opposite one of the terminals 19 at the end of the line sections 11, one connecting line 21 leads to the radiators or radiator groups 1.
- a remotely controllable motor means automatically pivotable tapping element arise from the respective attack or crosspoint 23 (ie the respective attack or coupling region 23) between the Abgriffelement 15 and the coupled therewith portion of the part-circular strip lines IIa and the stripline sections 11, IIa opposite terminals 19 different lengths of travel, whereby upon adjustment of the Abf 15 iff element 15 fed on one side of the Abf 1 emen ts 15 emitters runtime shortening and connected to the other side emitters a Laufzeitverinrung or - delay according to the path length Experienced. If the tapping element 15 is in its neutral central position (in the horizontal direction in FIG.
- the opposite connections 19 of a respective strip-line-shaped arc 11, IIa have the same phase position.
- the tapping element 15 can be adjusted in the embodiment shown to the maximum vertical upper end position and the maximum extending in the vertical direction lower end position, between these two end or extreme positions then the maximum phase shift can be generated with the phase shifter.
- FIG 2a is further, as mentioned, between the terminals 19 at the opposite terminal ends of the part-circular strip line sections 11 and a corresponding connecting line 21 is shown, which is used to feed in each case one suitable for a polarization plane radiator 1, for example, for the -45 ° aligned dipole-shaped or dipole-like radiator 1 ', for example, cross-shaped or dipolquadratähnlichen or vektordipolä Foundationen dipole radiator.
- a corresponding second phase shifter assembly 7 must be provided for feeding the second polarization plane of, for example, + 45 °, ie for feeding the emitters 1 ", which are operated in a corresponding polarization plane rotated by 90 ° this is not shown in Figure 2.
- all suitable radiators or radiator types can be used, for example also patch radiators, slot radiators, etc. There are no restrictions in this respect.
- radiators 1, 1 'and 1 "shown in FIG. 1 or FIG. 2a are arranged at equal distances D to one another in the direction of attachment as shown by the arrow 26, ie in an equidistant manner
- the distance S N from the phase-neutral center position Z (ie, the center Z of the antenna) and the most distant upper or far-lying lower radiator If or Ia is shown in FIG. 2a, as well as the distance S 1 , which corresponds to FIG distance from the phase-neutral center position (center) Z to the closest to this center Z above or below the neutral center layer Z provided emitters.
- phase shifter assembly according to Figure 2a, concentrically arranged, part-circular line sections 11, in particular strip lines IIa whose radii R N : R 2 : R 1 in a ratio of 5: 3: 1 arranged are, with respect to the center 17 of the part-circular strip lines IIa, which at the same time with the pivot axis 17 of the phase shifts in a fixed ratio of, for example ⁇ , 3 ⁇ , 5 ⁇ etc., so that, for example, as shown in Figure 2b, phase angles of + 5 ⁇ , + 3 ⁇ , + 1 ⁇ , - ⁇ , -36, -5 ⁇ , where ⁇ represents a phase angle resulting from the position of the tapping element and the associated propagation delay or propagation delay.
- Structure and operation of the phase shifter and the entire antenna arrangement is such that, for example, a feed signal to the central feed point 9 of the tap element 15 is guided and from there via the tap element 15 and the attack and coupling regions 23 then on the arcuate stripline sections in the radial Direction spreads. In this case, a part is decoupled to the innermost arc, a large part to the second arc, etc .. Since this propagation takes just as much time as the propagation on an arcuate stripline, these arches are also with different phases fed.
- the tapping member 15 is in the middle position, the running times on the two pipe sections of a sheet are the same.
- the bows 11, IIa according to their radii different maturities, ie the inner bow has in this respect again the shortest duration.
- the group antenna in this central position of the phase shifters have a beam swivel of 0 ", then the phases must be brought to the emitter to the same value .This is done by lines of different length from the phase shifter connections 19 to the emitters 1a to If but you usually only one beam drop down, ie the adjustment range should not be eg +5 ° ... -5 ", but for example 0 ° ... - 10 °.
- the line lengths 21 to the radiators Ia to If are thus selected so that the array antenna at central position of the phase shifter (ie at central position of the tap element 15) has a beam drop of 5 '.
- This is synonymous with equal phases at the radiators, when the phase shifter in the extreme posi tions "minimum beam reduction" is.
- the last column is normalized to the largest value, ie all other lamps require a correspondingly longer supply line.
- FIG. 2b shows the phases of the radiators Ia to If for an example as described above.
- FIG. 2b shows the phase positions Ph-L at the radiator connections 1a to If, for two different settings of the tapping element 15.
- the one data series (characterized by the bright points) describes the phase positions at the radiator connections when the tapping element 15 is in its an extreme position is located.
- the second data set (dark points) relates to the phase position Ph-L at the radiator ports Ia to If, when the tapping element 15 is adjusted to its opposite extreme position, in which the lowest radiator Ia the largest phase delay and the top radiator If the least phase delay.
- this example is chosen so that when adjusting the Abgriffeleraentes 15 in the one extreme position (bright measuring points in Figure 2b) radiate all radiators in phase, with the adjustment of the tap element 15 in the other extreme position, a maximum phase difference and thus a maximum down- Tilt angle is adjustable.
- FIG. 2c shows the differences Ph-D between the respective two phase values for the individual radiators 1a to If.
- the phase difference (as shown in Figure 2c), ie the phase shift produced by adjustment of the tap element 15, could also be determined directly by measuring the phase of a respective radiator, e.g. minimal beam reduction and subsequent measurement of the phase of the radiator with maximum beam reduction.
- Conventional measuring instruments offer the possibility of determining the first value as the reference value for the subsequent measurement. This would eliminate the subsequent calculation of the difference of the phase values.
- the phase shifter assembly according to the invention is preferably used for an antenna or antenna supply (antenna group), in which the individual emitters or emitter groups, that is to say the emitter arrangement 1, in the same Distance D from each other are arranged (ie, for example, the centers of the corresponding radiator arrangement are arranged at the same distance D to each other, which distances may vary in part.)
- the individual distances D between the radiator, radiator arrangements or radiator groups should be the same or a maximum of 15% or Preferably, the distances D should be equal to or less than 10%, in particular less than 8%, 6%, 5%, 4%, 3%, 2% and in particular less than 1%. differ from each other.
- the embodiment according to FIG. 3a now shows an embodiment according to the invention in which the distance, that is to say the radius R N of the outermost stripline section IIa to the center 9 or the pivoting axis coinciding therewith and the feed point 17 of the tapping element 15 and above all to the innermost concentrically arranged stripline section IIa is located farther than in the prior art embodiment, as shown in Figure 2a.
- the radii R N : R 2 : R 1 in the stripline sections IIa in conventional phase shifters, as shown in Figure 2a in a ratio of 5: 3: 1 (calculated from outside to inside towards the center) are arranged side by side, In the exemplary embodiment according to the invention according to FIG. 3 a, this ratio is selected to be 7: 3: 1, for example (the position of the outermost stripline section in the case of conventional design of the phase shifter, as in FIGS
- phase shifter assembly is preferably used according to the invention, which according to the following embodiments, two or more stripline arcs to a corresponding number of radiators or To feed emitter groups.
- a dif f erential phase shifter or a differential phase shifter assembly is also preferably used, in which by adjusting the Abgriffiatas the path length to the terminals 19 on the one side of the stripline sections are each smaller and the path length to the respective opposite terminals 19 on the various stripline arcs to a corresponding distance greater, in other words in one direction a term shortening and in the other direction a corresponding term extension is accomplished, whereby the different Phase adjustment or phase adjustment is effected.
- each of the arcuate stripline sections 11 ultimately has an inner radius, an outer radius, due to a radial width and a mean radius can be defined.
- the "middle radius” that comes to lie in the middle of each part-circular and strip-shaped line section 11. This average radius is decisive for the length of the arc and thus for the phase shift.
- FIG. 3c shows the disproportionate phase change with respect to the two most distant radiators 1a or if.
- this ratio should be chosen so that the radius ratio R N : R 1 between the outermost lying N-th stripline section and the innermost stripline section (ie, the center 9 and thus the feed point 17 of the tap element 15 is closest), about which the radiator or radiator subgroups are driven, using three stripline sections IIa without phase-neutral center control (ie at a even-numbered array antenna with an even number of radiators and / or radiator groups) has a value of
- a group antennas is fed with a phase shifter arrangement, in which the antenna group comprises an even number of radiators or radiator subgroups.

- the center Z of the array corresponds to the phase-neutral center layer, which is also at differently adjusted phase position unchanged remains.
- Ph N Ph 1 > S N : S 1 + k
- k corresponds to a value of 0.4, in particular 0.5, 0.6 or preferably 0.8.

- Ph N Ph 1 > S N : S 1 + k

- FIG. 11a Similar to the diagram of FIG. 3c, a diagram is shown in FIG. 11a for the exemplary embodiment according to FIG. 9a, from which it can be seen that the terminals 19 of the largest stripline arc of the phase shifter experience a disproportionately large phase shift for the most distant radiator or radiator groups.
- a phase shift with respect to the emitter or emitter groups closest to the center of the antenna is achieved by means of the smallest stripline arc which undergoes a disproportionate phase shift (shown in FIG. 11b).
- FIGS. 12a to 12d there are radiation diagrams for a six-element comprehensive
- Array (as generally described with reference to FIGS. 5a to 5d), ie a group antenna, which comprise an even number of radiators or radiator subgroups and are not fed with a phase position independent of the phase shifter setting for a central radiator or radiator group.
- the mentioned six radiators 1 are positioned in the embodiment shown at a distance of 285 mm in the vertical direction.
- FIG. 12a shows the radiation pattern without lowering the main lobe.
- the first upper sidelobe points towards 16 'elevation and has a level of -13 dB.
- FIG. 12 b shows a variant in which the phase shifter according to the prior art has a radii ratio of 1: 3: 5, ie that it generates a phase shift with respect to the individual radiators in this ratio. These phase shifts occur both at the phase shifter outputs and at the radiator terminals. Since there are differences between the phases of each emitter at two different settings, the values are independent of the respective supply line lengths of the individual emitters.
- FIG. 12b shows a beam reduction according to the prior art. Neighboring emitters each have the same phase difference. If one chooses the center of the antenna as a reference, then the phases of the radiators are at -125 ', -75', -25 * , 25 ", 75 ', 125" (from bottom to top). One sees a main lobe lowered by 9 °, whereby the first upper side lobe is likewise lowered and now shows in elevation 7 °. The side lobe level has increased by 0, 6 dB to -12.4 dB.
- the changed shape of the diagram reduces the gain of the antenna slightly by 0.2 dB or 0.3 dB compared to the prior art when the main beam direction is lowered to 9 °. This is tolerable because the coverage area is also correspondingly small. If no or the minimum beam reduction is set, the diagram has the same shape as in the prior art, and there are no profit losses.
- FIGS. 13a to 13d which generally correspond to the variants according to FIGS. 9a to 9d
- a 7-element array that is to say a group antenna with seven equally spaced radiators or radiator subgroups middle emitter or a central emitter subgroup is fed phase-neutral, so undergoes no phase change with different setting of the tap element of the phase shifter module.
- FIGS. 13a to 13d The different steel sinkings shown in FIGS. 13a to 13d are shown in the following table:
- Beam angle Angle 1 Level 1. Upper upper sidelobe Side lobe
- FIG. 13 C 9 ' 4' -16, 2 dB The mentioned seven radiators are positioned at a distance of 285 mm in vertical direction.
- FIG. 13a shows the radiation diagram without lowering the main lobe.
- the first upper sidelobe points towards 14 * elevation and has a level of -13.1 dB.
- a modified phase shifter is now used, with a radius ratio of 2: 4: 6 (1: 2: 3), or produces phase shifts per emitter in this ratio. These phase shifts occur both at the phase outbreaks and at the radiator terminals. Since these are differences of the phases of each emitter at two different settings, the values are independent of the respective supply line lengths of the individual emitters.
- FIG. 13b shows a beam drop according to the prior art. Neighboring emitters each have the same phase difference. If one chooses the center of the antenna as a reference, then the phases of the radiators are at -150 ', -100 °, -50', 0 ", 50 °, 100 °, 150 ° (from bottom to top) 9 ° lowered main lobe, whereby the first upper side lobe is also lowered and now shows 4 ° in elevation The level of the side lobe has increased by 0.5 dB to -12.6 dB.
- a modified phase shifter is now used, with a radius ratio of 2: 4: 7 (1: 2: 3.5).
- the phases of the outer radiators now change amplified, and, again relative to the center of the antenna, they now lie at -157 °, -90 ', -45 ". , 0, 45 ', 90 °, 157 °.
- the first upper side lobe in Figure 13c shows in elevation 4 °, the level now being at -16.2 dB, ie 3.6 dB lower than in the prior art.
- FIG. 13d The effect is even more pronounced for a phase shifter with a ratio of 2: 4: 8 (1: 2: 4) or a similar phase shift ratio.
- the result is shown in FIG. 13d. While the radiation pattern according to FIG. 13a also applies here for a beam reduction of 0 °, the outer radiators experience a further increased phase change. A dip of 9 ° is achieved when the centers of the radiators are at -164 °, -82 °, -41 °, 0 °, 41 °, 82 °, 164 °. The first upper sidelobe at 4 ° has now even dropped to a level of -21.7 dB, which is an improvement of 9.1 dB over the prior art.
- the changed shape of the diagram reduces the gain of the antenna slightly by 0.2 dB or 0.3 dB compared to the prior art when the main beam direction is lowered to 9 °. This is tolerable because the coverage area is also correspondingly small. If no or the minimum beam reduction is set, the diagram has the same shape as leg
- the corresponding ratios are reproduced when an antenna with a 7-element array is used, in which the wheel increases the outer edge strip section compared to conventional solutions, and at the same time the radius of the inner stripline section is reduced, as shown schematically in principle with reference to Figure 10d.
- the radiator arrangement as in the previous example according to the figures 13a to 13d, also consists of seven radiators corresponds to the radiation pattern resulting in this embodiment without lowering that of Figure 13a, further comprising a radiation pattern with a beam reduction according to the prior art
- This exemplary embodiment corresponds to that exemplary embodiment according to FIG. 13b.
- the gain of the antenna slightly reduces by 0.2 dB or 0.3 dB compared to the prior art, when the main beam direction is lowered to 9 '. This is tolerable because the coverage area is also correspondingly small. Is no or the minimum beam reduction set, the diagram has the same shape as in the prior art, and there is no loss of profit.
- phase shifter assembly which comprises two or more partially circularly arranged stripline sections over which a tapping element can be adjusted.
- Such an assembly may, as explained, be used for an even-grouped or odd-numbered element antenna array, depending on whether or not a center radiator or a radiator group is driven without phase shifting.
- strip lines may also be used which have different center points.
- the outermost radius R N is increased relative to the other radii (ie no longer coincides with the center of the other radii), so that, for example, the outer radius becomes infinite in the extreme case and the stripline section progressively increases from a partial arc a straight line, ie in extreme cases exactly to a straight line. This ultimately leads to a shift of the coupling point 23 on the tapping element.
- the ratio of the radii starting from a standard radii ratio of, for example, 1: 2: 3 (for example in the case of the odd number of radiators or radiator groups) or with a standard radii ratio of 1: 3: 5 (for example, in an antenna with an even number of radiators or Radiator groups) is maintained if, for example, the outermost stripline with the largest radius has one or preferably two (on opposite sides - ie up and down - relative to the stripline) dielectric intermediate layers. It is only essential that the chosen dielectric (ie deviating from air) reduces the phase velocity of the signal on the arcuate stripline.
- the phase shifter according to the invention can be constructed with or without upper shield. In this case, the dielectric is most effective when it is between the arcuate stripline 11, IIa and their ground plane. Any dielectric material above the line that overlaps the line has less of an impact because it is only in the stray field of the microstrip line.
- the mentioned one or more dielectric interlayers may, for example, also be formed only on a partial length of the arcuate strip lines, be provided with a different density over the length of the sheet or a partial length, decrease or increase over the length or a partial length or else a different dielectric constant exhibit.
- the phase angles with adjustment of the phase shifter respect. of the outermost stripline arc to the innermost stripline arc non-linear, but disproportionately change.
- a factor K can be defined. On the condition that the entire arc length is carried out in this way, the ratio of the maximum phase velocities at the phase shifter connections or at the radiator connections is then, for example: 1: 2: (3 / K)
- phase shifter assembly with three strip lines, via which an antenna with odd-numbered radiators or groups of radiators (ie seven radiators or radiator groups) is fed.
- N represents the number of stripline sections as outlined in an odd number of radiators or radiator groups.
- the dielectric material may be chosen to have a relative dielectric constant ⁇ of 30.
- K the maximum phase velocity
- Particularly interesting are those cases where the radius of the outer stripline Arc 11, IIa is not enlarged compared to the standard case. This does not increase the overall space requirement of the phase shifter.
- a radii ratio of 1: 3: 5 a phase shift ratio of 1: 3: 6 can thus be achieved, with a value for K of approx. 0.83. If the value of K were reduced to about 0.71 with the same radii ratio, a phase shift ratio of, for example, 1: 3: 7 would result. This illustrates how a comparable effect is achieved by using corresponding dielectrics, ie whether the radii of the individual stripline arcs are changed accordingly.
- FIG. 15 shows a schematic cross section for such a phase shifter which has, for example, three stripline arcs 11 arranged in a standard radii ratio of 1: 2: 3, if in the center Z an additional radiator or an additional radiator group of the phase-neutral center layer the antenna is powered.
- the outermost strip line in this case has the aforementioned two dielectric intermediate layers 55, which are arranged above and below the outermost stripline bow 11.
- the bottom or the bottom plate 71 as well as an associated, likewise electrically conductive cover or housing cover 73 are drawn, from which it can also be seen that the dielectric intermediate layers 55 are fastened once to the bottom 71 or to the inside of the cover 73
- the outermost stripline arcs 11, 11a are on the dielectric 55 positioned and held on the ground rests and is provided at a distance above the attached to the inside of the lid 73 dielectric 55, in such a distance to the outermost S t reindeer sheet 11, that even the tapping element on the stripline sheet 11, IIa between the two Dielectrics 55 can be adjusted.
- phase shifter position Due to the mentioned use of dielectric material with a constant arc radius, the resulting phase shift is therefore ultimately increased. If the mentioned dielectric were not uniformly placed along the preferred outer stripline arc, the achievable phase shift would ultimately depend on the choice of the phase shifter position.
- phase shifter assembly as discussed and described is used but, for example, individual phase shifters, e.g. a single differential phase shifter only a single part-circular line section and an associated tap element, about which only one emitter or one emitter group can be fed at the two terminal ends.
- individual phase shifters e.g. a single differential phase shifter only a single part-circular line section and an associated tap element, about which only one emitter or one emitter group can be fed at the two terminal ends.
- the principle according to the invention is based on simultaneously generating a disproportionate increase in the phase difference when driving an increasingly larger down-tilt angle, with which the farthest one Spotlights are fed in relation to the innermost radiators.
- the invention has been described with reference to a group antenna, in particular for a mobile radio system, which is about the reduction of the down-tilt angle.
- the invention can just as well for a horizontally oriented
- Antenna array can be used in which the
- Stripline section reproduces.
