Description

The invention relates to a dual polarized group antenna, in particular mobile telephone antenna according to the preamble of claim 1.

For mobile phone antennas, batteries of single- or multi-column antennas are generally used, which usually include in each column several emitters or transmitting equipment arranged one above the other in a vertical direction. Often dipole emitters can be used here for example in the form of dipole crosses, dipole squares or so-called vector dipoles, as are known for example from WO 00/39894 A1 or WO 2004/100315 A1. But other emitters and forms of emitters are also possible, for example patch emitters.

It may be a matter of a single-band, dual-band or preferably multi-band antenna configuration, which preferably emits and receives not only in a polarization plane, but in two polarization planes perpendicular to each other. These polarization planes are preferably oriented by way of a so-called X polarization, that is to say that both polarization planes perpendicular to each other are oriented at an angle of + 45� and -45� respectively relative to the horizontal (or vertical well).

A polarized group antenna known to the state of the art must usually be able to generate two coincident or controllable radiation diagrams coincidentally, precisely for each of both linear polarizations, that is, for both polarization planes perpendicular to each other. . these must be electrically independent of each other. On the one hand, the cross polarization distance of the radiation must therefore be very large. In addition, the coupling between the antenna connections must be very low, that is, the decoupling (isolation) must be very high.

This is so basically for any frequency band. In this regard, all specifications for the full frequency range (frequency band) must be met. This is also true in the case of a dual band or even multiband group antenna, since more and more frequency bands are now assigned to mobile telephony. A mobile telephone antenna must currently cover a frequency range of for example 1710 MHz to 2690 MHz. This corresponds to a bandwidth of 980 MHz or a relative bandwidth of 45% based on the center frequency. Therefore, it is increasingly difficult and more demanding to comply with all conditions over such a large frequency range. In addition, there is the aggravating factor that, in this case, a second frequency band, for example 806 MHz to 960 MHz, is also prescribed and that the emitters and transmitting equipment are then partially realized, as already indicated, as dual issuers or they should be. This increases the total number of emitters and emitting elements between which interactions can occur.

Finally, a group antenna may also include several contiguous columns, so it is necessary to take into account not only the decoupling between two polarization planes perpendicular to each other in terms of the emitters or emitting equipment of an antenna column, but also additionally decoupling between equal polarizations in emitters arranged in two different antenna columns.

Starting from this base, a particular group antenna is needed with better decoupling between the two polarizations. This is, for example, both for a dually polarized single-column antenna and also for a multi-column antenna.

Thus, according to WO 00/31824 A1, a group antenna that includes spatially separate groups of single polarization emitters for each polarization has already been proposed. But this creates a great need for space, so such systems cannot be realized in practice.

According to WO 2004/051796 A1 a battery of two-dimensional grouped antennas has been proposed, in which it is provided in each of the columns that run vertically, of which there are at least two, the respective configuration of emitters, that feed each other separately. Then, for example, in the second column at least one transmitter or one transmitter configuration is provided, which is fed together with the emitters or transmitter configurations of the first antenna column. Conversely, it is provided in the first antenna column at least one transmitter or one transmitter configuration that is fed together with the transmitters in the second antenna column. This is definitely useful for beam formation without having to make an improvement in decoupling.

Also according to WO 2008/060206 A1 a battery of antennas with dual polarized transmitters is proposed, which at the edges have respective zones with single polarization emitters with the same polarization. In this regard, the number of interconnected transmitters in a group is different. A different radiation pattern must also be generated. In other examples, a two-column antenna is proposed, in which for example in the first column only emitters are oriented in a polarization direction and in the second column the transmitters are only in a polarization plane perpendicular to the previous one, being different the distance of the transmitters oriented with the same polarization plane in both columns of the antenna. All these measures serve, as indicated, to generate different radiation patterns.

Based on this basis, a prior art must be taken into account in the context of the present application, as is basically shown in Figure 10.

A known antenna battery corresponding to the state of the art according to FIG. 10 presents, for example, several emitting equipment 3, which are configured as dual polarized emitting equipment and for this purpose include transmitters or emitting elements 3a that are powered, that is , emit and / or receive in a first polarization plane P1 and second emitters or emitting elements 3b that receive and / or emit in a second polarization plane P2 perpendicular to the first polarization plane P1. Preferably, both polarization planes are oriented at a flat angle of +/45� in the vertical or horizontal.

The emitting equipment mentioned and shown in Figure 10 are then arranged in a mounting direction 5 (linear configuration) next to each other, in the example shown one above the other. In this sense, there is also talk about a group antenna of a column, that is, a group antenna with an antenna column 7 that is usually oriented vertically or predominantly in the vertical direction, but basically also in the horizontal direction and in any other direction with a vertical and horizontal component. For reasons of simplicity, an antenna column is always discussed in this sense regardless of orientation.

The said emitting equipment 3 is then usually arranged in front of a reflector 1. The polarized emitters can be, for example, dipole-shaped emitting equipment, for example dipole crosses, dipole squares, vector dipoles, etc., such as those they are known for example from said document WO 00/39894 A1. They are also considered patch emitters and other emitting equipment. In this sense there are no limitations.

By means of such a configuration of antennas known by the prior art, a polarized antenna is created with radiation diagrams of the same type, that is, at least very similar, for both polarizations. In other words, such an antenna configuration has approximately the same lobe widths for the radiation pattern in one of the polarization planes P1 as in the other polarization plane P2.

In this regard, the emitters 3a are fed in relation to one of the polarization planes P1 by means of a network N1 and, on the contrary, the emitters 3b that emit in the second polarization plane P2, are fed by the network N2.

Contrary to the state of the art creative technique described in Figure 10, a dual polarized antenna configuration has been disclosed in different embodiments also by WO 2008/060206 A1. According to Figure 4 of this previous publication, an asymmetric antenna is described, for example, which includes dual polarized antenna configurations, arranged spaced apart from each other in front of a reflector in a mounting direction. In this regard, six emitters are provided for example in one of the polarization planes and, in contrast, in a second polarization plane perpendicular to the previous eight emitters, for which, above and below the polarized emitters, it is planned in each case an additional emitting element, of simple emission and which is in the same polarization plane.

From US 2003/189516 A1 a battery of antennas with multiple patch emitters should be considered known. This battery of antennas that uses patch emitters includes a first beam-forming network, by which the patch emitters that sit next to each other in a first row are fed, which for example emit in an inclined polarization plane given the case at an angle of + 45� with respect to the vertical.

In addition, a second beam-forming network is provided, by means of which, for example, the patch emitters arranged next to each other in the lower row are fed, which emit in a polarization plane oriented perpendicularly to the first polarization plane before cited, that is, for example at an angle of -45� with respect to the vertical.

Finally, a third row of patch emitters arranged between the first and the third row are also additionally arranged, which are polarized twice and are fed by both beam-forming networks with respect to both polarization planes.

From US 6 211 841 B1 a battery of antennas with multiple dual polarized transmitters, arranged in two antenna columns sideways side by side, must be considered known. In this regard, dual polarized transmitters are provided for a lower frequency band, as well as dual polarized emitters emitting in a higher frequency band.

From WO 03/083992 A1, a dual polarized multiband antenna whose main radiation direction can be adjusted must be considered known. For this, a downtilt control device (downward tilt) is known for the control of the polarization plane oriented at + 45� or emitters, as well as other downtilt control equipment to control the emitters oriented at -45�, which emit in the background of polarization.

Finally, a dual band antenna, in which second-rate transmitters in the second frequency band are provided in the second frequency band, are also known to be known from EP 1 353 405 A1 distance from each other, compared to the emitting equipment that emits in the low frequency band.

Starting from this state of the art, it is now the task of the present invention to achieve an improved antenna battery that can basically be configured with a single column or also with several columns and that can operate in a band or preferably also in several bands, and must be achieved with simple means a better decoupling between polarization of polarized emitters dually in one column and / or a better decoupling in terms of emitting equipment of the same polarization plane in adjacent antenna columns. Then you must generate the battery of antennas corresponding to the invention, similar to in the state of the art type generator (as described based on Figure 10 of the present application), for both polarizations (polarization planes) preferably a radiation pattern as similar as possible and / or symmetrical, in which the lobe widths of the radiation diagrams are as much as possible in the same order of magnitude for both polarizations.

This task is solved within the framework of the invention with the characteristics indicated in claim 1. Advantageous configurations of the invention are indicated in the dependent claims.

The solution corresponding to the invention is now characterized in that a polarized group antenna dually includes at least two groups with in each case three different zones or three different emitter configurations or power types of the emitter configurations, being provided that at least one and preferably several emitting equipment are fed as for both polarization planes perpendicular to each other and because each antenna column is associated with at least in each case other additional emitting equipment, which on the one hand is only fed in the first polarization plane and on the other hand only in the background of polarization. The configurations of additional emitters can be single polarization emitters or equally dual polarized emitters, which unlike the other emitters are only fed in a polarization plane.

In this regard, the total number of transmitters powered by the antenna is equal in group with the first and second polarization.

Both groups of dual polarized antennas, which emit in ranges of similar or equal frequencies, can be arranged here one after the other along a single column. Within the framework of the present invention, a polarized transmitter can be used dually at the center for example of the + 45� polarization of the first antenna and at the same time of the -45� polarization of the second antenna. Above and below, single polarization emitting equipment can then be arranged, which emits once in one of the polarization planes or in the other polarization plane. In this regard, there is a dual polarized emitter structure in the central zone whose emitter emitting in one of the polarization planes is fed by a network of the first antenna in group and whose emitter emitting in a perpendicular polarization plane is fed by a network of the second antenna in group.

When two antenna columns are found next to each other, then there may be additionally polarized emitters, one of whose polarization planes is associated with one column and whose other polarization plane is associated with the second antenna column, that is , in each case transmitters or transmitting equipment powered (s) in each case on one or the other antenna column.

Usually polarized antennas are constituted as similarly as possible, to obtain similar radiation patterns in both polarization planes. Then the best decoupling would also be expected in a symmetrical structure. Therefore, it is all the more surprising that in the context of the invention an improvement is achieved by an asymmetric configuration of the antenna battery, since within the framework of the invention the configuration of the emitters and / or the operation of the emitters is no longer they are necessarily similar or symmetrical, since the occupations and / or positions of the emitters or active emitting equipment of the groups of emitting equipment belonging to both polarizations are different. In part, both polarizations of a dual polarized emitter are used in parallel (as so far), with other single or dual polarization emitters spatially separated from each other being provided in the context of the invention, but in the case of Dual polarized emitters only work in a polarization plane. However, this structure, which in itself is only slightly more expensive, ultimately results in a partial separation in the space of both polarization planes, which surprisingly contributes to the better decoupling. The decoupling improvement can then be so great that together all other specifications or radiation patterns, adaptations and the desired requirements regarding the possibility of broadband can also be met.

The invention will be described in more detail below on the basis of drawings. In this regard they show in detail

Figure 10: A battery of antennas, as known according to the state of the art.

Next, a first more detailed example will be described based on Figure 1. In this regard, the same or similar elements will be designated with the same references, as in the description of the group antenna known by the prior art according to Figure 10.

In other words, a reflector 1 is provided in the example of figure 1, in front of which they are provided in the mounting direction 5 - in the example shown at equal distances - in vertical direction one above the other at a certain distance in front of the reflector plane emitting equipment 3, whose emitting elements 3a emit in the polarization plane P1 and whose emitting elements 3b emit, that is, send and / or receive in the polarization plane P2, both polarization planes being perpendicular to each other. � and being oriented (at least approximately oriented) at an angle of +/- 45� with respect to the vertical or horizontal.

The elements emitting in one of the polarization planes P1 are then fed through a network N1 and on the contrary the emitting elements 3b operating in the second polarization plane P2 are fed by the network N2. In the example shown, it is a monoband antenna.

In the same example, it is now foreseen that, together with the four central emitting equipment 3 (which operate and are fed in both polarization planes), a more superior emitting equipment 103a is provided, which is also fed through the first network N1 together with the other emitters 3a fed from the same polarization plane P1 and that a lower emitter equipment 103b belonging to the antenna battery is provided, which with the other emitters 3b operating in the second polarization plane P2 is fed by the second network N2.

This configuration now provides for each polarization plane n emitters or emitting elements or emitting equipment 3, in the exemplary embodiment shown five emitters or emitting elements, operating the four central emitters in both polarization planes perpendicular to each other and the equipment uppermost emitter through the network on the right N1 and the lowest emitting equipment 103b (oriented perpendicularly to the uppermost emitting equipment 103a) through the network on the left N2. In other words, there are thus in total n + 1 emitting equipment 103a, 3, 103b arranged one above the other, that is, in this example six emitting equipment arranged one above the other, that is, in each case five active emitting equipment for each polarization plane P1, P2. In other words, there are provided in this example n emitters in each case in a polarization direction P1 or P2, for example bipolar emitters, resulting in the height offset in the difference d between the emitters emitting in a plane of linear polarization P1 and the emitters that emit in the other polarization plane P2, in total n + 1 emitter positions, that is, four emitters polarized twice and respectively an upper emitter and a lower emitter of simple polarization.

Thus, at least three different antenna zones result in the described antenna, that is, a central zone X2 with dual polarized emitters 3 as well as other emitter zones X1 and X3 respectively upper and lower (in each case in the ends of the configuration of antennas close to the central emitter zone X2), where at least one transmitter configuration 103a and 103b respectively is arranged in each case as regards the antenna or the group antenna in question respectively, which they emit only in one or only in the other polarization plane.

In this sense, at least in part, we are talking about at least one first sending equipment 103a, at least one second sending equipment 3 and at least one third sending equipment 103b, the first sending equipment 103a being arranged, of which at less there is one, in the aforementioned first emitter zone X1, the second emitter equipment 3, of which there is at least one, in the aforementioned second emitter zone X2 and the third emitter equipment 103b, of which there is at least one, in the aforementioned third emitter zone X3. In other words, at least a second transmitting equipment 3 is arranged in the central zone X2 between both first and third zones X1, X3 located offset between each other, being provided in a mobile telephone antenna oriented at least essentially vertically one of zones X1 in the upper part and the third zone X3 in the lower part.

The corresponding offset of the emitting equipment arranged consecutively or one above the other in the mounting direction can then be the same in the whole antenna in group, that is, it can also correspond to the distance d between the uppermost emitting element 103a and the emitting element contiguously doubly polarized 3, as well as between the lower emitter element 103b (ie, the corresponding center of this emitter 103b) and the doubly polarized emitter 3 that is above. However, the distances may also be configured differently from one another, therefore not necessarily having to be the same.

Already at this point it should be noted that not all dual polarized or single polarized emitters 3, 103a, 103b must be arranged exactly on one line in the mounting direction 5 one after the other. It is also perfectly possible that one or the other of the emitters is also transversely offset with respect to the assembly line, or for example it is also positioned on an adjacent antenna column. Obviously, the radiation pattern is also modified, which is not the primary objective of the present invention.

In the example of FIG. 2, it is now foreseen that only both centrally polarized emitting equipment 3 operate both the polarization planes and, on the contrary, two emitting equipment 103a are already provided which are located above, with simple polarization and that they emit in one of the polarization planes P1 and two emitting equipment 103b that are below with single polarization, which both operate in the second polarization plane B2.

In this case, there are provided for each polarization n emitting equipment with simple polarization, that is, in the example shown four, with which result in total n + 2, that is, six emitting equipment 103b, 3, 103a arranged one over another, being of simple polarization four in each case and operating two polarized twice, in each case through the respective networks N1, N2.

In this example, two first emitting equipment 103a, two second transmitting equipment 3 and two third transmitting equipment 103b are therefore provided.

In this example it is further clarified that the distances d between the positions (centers) of both centrally polarized central equipment, as well as between the corresponding emitting equipment 103a that are above, with simple polarization and arranged adjacent to each other, are equal and less than the distance between the positions d of the dual polarized emitting equipment 3 below and the corresponding emitter element 103b with simple polarization that follows or between the emitting elements 103b biased at both ends.

Very generally, it is therefore the configuration such that in n emitting elements for the corresponding polarization, 1, 2, ... can be configured up to a maximum of n-1 emitters as singularly polarized, so that in short they are configured m = n-1, m = n-2… up to at least m = 1 emitter configurations as dual polarized emitter configurations, which operates at the same time in two polarization planes located perpendicular to each other.

In the example of figure 3, the function described above has been further expanded, with five emitting devices being provided for each polarization in this example. The first three emitter units 103a that are higher in the upper zone X1 emit in a polarization plane P1 and on the contrary the three emitter equipment 103b that are lower in the zone X3 emit in the polarization plane P2 oriented in perpendicular to the previous one. Only both second emitting equipment 3 that are in the central zone X2 are configured as dual polarized emitting equipment.

For the advantages corresponding to the invention, it is irrelevant if the single polarization emitters above emit in the polarization plane P1 and the single polarization emitters below emit in the polarization plane P2 or vice versa.

Also in this example, therefore, for each polarization plane n emitters are therefore provided, in the example shown therefore five, m being configured of these emitters as dual polarized emitters, precisely both central ones, whereby in this example m corresponds to number 2. Consequently, nm emitters 103a and / or 103b of single polarization are provided. Also in this example it can be the minimum number m 1, with which at least one emitter polarized dually in the center is provided. If, unlike in figure 3, it were for example m = 3 � m = 4, three or four polarized transmitters would be provided accordingly (in the center of the antenna battery) one above the other, which in this case for nm = 5-3 = 2 only two upper emitters and two lower emitters of single polarization would be provided or in the other case nm = 5-4 = 1 only one upper and lower emitter polarized differently, single polarization 103a and 103b respectively, in all these examples being n and whole natural numbers and having to be n at least three or greater, to constitute three zones of different antennas X1, X2 and X3, precisely a zone of antennas X2 with at least one dual polarized emitter and at at least in each case two zones X1 and X3 with at least one emitter polarized twice, once in a polarization orientation and again in a polarization orientation perpendicular to the previous one. Then you can always assume m values 1, 2, ... up to a maximum of n-1.

In other words, a first sending device 103a and a third sending equipment 103b (together with one or several second sending devices 3) are therefore provided or are provided (together with one or several second sending devices 3) several first and third emitting equipment 103a, 103b, the amount of first emitting equipment 103a always corresponding to the number of third emitting equipment 103b. Thus, there is always the same number of first emitting equipment 103a and third emitting equipment 103b. For this reason it can also be said that zones X1 and X3 include in each case the same amount of emitting equipment, emitting the first emitter or the first several emitters 103a always in one of the polarization directions and the other third emitter or the various third equipments emitters 103b in a polarization direction perpendicular to the previous one.

In Figures 3a to 3c it is shown schematically again how the described antenna is basically constituted. Figure 3a again shows that, for example, five emitter configurations are arranged, which emit in each case in the polarization plane P2, with a distance between positions d one over the other, with which the five emitters emitting in the Polarization plane P2 are positioned in positions 1P2, 2P2, 3P2, 4P2 and 5P2.

In figure 3b, five emitting elements are arranged at the same distance between positions d one on the other, which emit in the polarization plane P1 perpendicular to the previous one. These five emitting elements are then arranged in positions 1P1, 2P1, 3P1, 4P1 and 5P1. The emitting elements shown in Figure 3b, which emit in the polarization plane P1, are then arranged offset upward in a triple offset of 3xd with respect to the emitting elements shown in Figure 3a on the left which emit in the P2 polarization background. This results in Figure 3c to that (when the emitting elements are arranged together in the first polarization plane P1 and in the second polarization plane P2 in the vertical direction of mounting one above the other) the emitters arranged in the position 1P2 and 2P2, which emit in the second polarization plane P2, meet with the emitters arranged in the fourth and fifth positions 4P1 and 5P1, which emit in the polarization plane P1 to form dual polarized emitters and according to the result of the Figure 3c the first emitting equipment 103a emitting or operating in one of the polarization planes P1 is formed above, both second emitting equipment 3 being configured below, configured as dual polarized emitters and below three third emitting equipment 103b emitting in the second P2 polarization plane.

In general it can be said that the emitters relative to one of the polarization planes that are fed through one of the N1 networks, with respect to the emitters that emit in the other polarization plane and that are fed through the second N2 network , they are arranged offset in one or several units of distance d, that is, arranged in the mounting direction 5 offset relative to each other, the distance corresponding to the distance between two adjacent emitting equipment corresponding. This results in a complete solution, in which in each case an element that emits in one of the polarization planes P1, which is fed by one of the networks, is joined with an emitting element arranged in a relatively higher position or lower that emits in the second plane of polarization P2 and that is fed by the second network, to form a common emitting element polarized dually. By means of the offset in the mounting direction of the emitting elements in one and in the other polarization plane, thus, they are located up and down, that is, generally offset in the mounting direction, first emitting equipment 103a and third emitting equipment 103b, of which the first emitting equipment 103a only emits or operates in a polarization plane P1 � P2 and the third emitting equipment 103b only in a polarization plane P2 or P1 in each perpendicular case.

Based on Figure 4, an example similar to that of Figure 1 will now be described. In this example it is only different than contrary to Figure 1, in the highest and lowest position (zone X1 and zone X3, respectively) a first or third dual polarized emitter 3 is arranged, this first or third polarized emitter being able to correspond correspondingly to the structure and configuration to the other dual polarized emitters 3, but not being necessary. Of course, only the first emitter located above and doubly polarized is fed into one of the polarization planes P1, therefore having the effect of a single polarizing emitter 103a of Figure 1.

The third emitter 3 disposed in the lower part in the zone X3 and polarized dually, is fed only in a second plane of polarization P2 perpendicular thereon, therefore having in the electrotechnical aspect only a function such as that of the emitter 103b simple polarization of the figure

one.

In this example, it therefore presents n the value 5, since for each polarization plane five emitting equipment is provided, the value being for m 4, since four emitters polarized are planned twice in the center and only one upper and lower emitter, which are certainly configured as dual polarized emitters, but only emit in a polarization plane. Then, as indicated, the circuit of the polarized emitters can be different, that is, they can be formed for example as a dipole cross, as a dipole square, as a vector dipole or as a patch emitter (patch), etc. . The types of issuers do not necessarily have to be identical.

In all the previous examples as well as in the following, to achieve a sufficiently similar configuration of the radiation pattern, the number of emitters 103a only fed in one of the polarization planes P1 is identical to the amount of emitters 103b fed in the other P2 polarization plane. In this regard, they are provided in the examples shown between the emitters 103a, 103b configured as single polarization emitters or the polarized emitters 103a, 103b that operate only in a polarization plane (ie, between the highest and lowest positions of the antenna battery) the emitting equipment 3 polarized twice and fed in both polarization planes in the central zone of the antenna battery.

Therefore, in general, the emitters oriented in each case in a polarization direction P1 or P2 or dual polarized emitters emitting in this polarization plane are arranged in antenna positions that are offset up and down with respect to the center of the antenna battery, whereby the emitters or configurations of emitters emitting in both polarization planes are provided in the central positions of the antenna battery.

On the basis of figure 5 a variant is described which includes a group antenna with an antenna structure corresponding to that of figure 1. Of course, the group antenna described here based on figure 5 is configured as a group antenna dual band, the antenna system being represented with the transmitting equipment 55 for the lower frequency band Fn in the form of a square. The antenna system for the higher frequency band Fh is thus arranged within the antenna in dual polarized group and configured as a dual band, representing the emitting equipment represented in the form of a cross, for example in the form of dipole or square crosses. dipolar, the corresponding dual polarized emitters of the higher frequency band Fh and the emitting equipment 103a, 103b represented as lines, the single polarization only transmitters of this high frequency band Fh (corresponding to the example in Figure 1). The corresponding networks N for supplying the single or dual polarization emitting equipment 55 for the lower frequency band Fn have not been drawn for simplicity and clarity in Figure 5, but have been left out.

Also in this example, dual polarized emitters 103a, which only operate in one of both polarization planes, can be used instead of the single polarization emitters 103a, as described on the basis of Figure 4. They may also be provided several higher and several lower single polarization emitters or dual polarized emitters, which only operate in a polarization plane, as described based on Figure 2 and Figure 3.

In the example of figure 6 corresponding to the invention, two groups of polarized antennas are arranged in the mounting direction 5, that is to say, vertically one above the other, a first group A being constituted basically with both networks N1 and N2, as in the example of figure 1.

Also the second group B with the corresponding emitters and emitting equipment is constituted in the same way, feeding the emitters or emitting elements 3a that emit in the polarization plane P1 through the network N11 and the emitters or emitting elements 3b which emit in the second plane of polarization P2 through the second network N22.

In this regard it is the configuration such that the emitting equipment 3 in the center of the whole antenna in group as regards one of the polarization planes P1 by means of the lower antenna group A and the second polarization plane perpendicular to it P2 is fed to via the N22 network of the upper antenna group B. In other words, the first single polarization antenna element 103a is practically assembled here and found in Figure 1 above in the first zone X1 with the third antenna element 103b polarized perpendicularly in this regard and found in the upper group below in zone X3, to form a doubly polarized antenna element, which is fed in both polarization planes through both groups.

In this exemplary embodiment, the three emitter zones X1, X2 and X3 are therefore provided for each of both groups of antennas A � B, the area of antennas X1 of the lower antenna group A coinciding with the zone of antennas X3 of the upper antenna group B, whereby a dual polarized emitter 103 'can be used here, which is fed in one of the polarization planes P1 by the network N1 of the lower antenna group A and in the other polarization plane P2 through the N22 network of the upper antenna group B.

In the same way, the example of execution of Figure 6 could be different, so that in the emitters that emit in one of the polarization planes P1 and those that emit in the other polarization plane P2 in both groups, they not only meet in a offset d in the vertical direction, but for example in a double step 2d � 3d, etc., with which two or three are provided in each case, etc. single polarization emitters in each case below the whole and above the whole (or dual polarized emitters that only emit in a polarization plane) and such that in this case two or three are provided, etc. centrally polarized dual emitters, of which two, three, etc. they are fed by one of the N1 networks of the first group A of antennas and these polarized transmitters are doubly fed in the center of the antenna battery as for the second plane of polarization P2 via the N2 network, since the emitter components that emit in the plane they belong to the second group of antennas B. In other words, the offset or the amount of single polarization emitters can also be similarly performed here, as described basically in the preceding exemplary embodiments 1 to 5.

An example is now shown in Figure 7 concerning a battery of two-column antennas, in which the corresponding emitters and emitting equipment are positioned in column 7a and in an antenna column 7b arranged on the side that also runs vertically and in parallel to the first antenna column. The sending equipment may be constituted in each of both columns according to one of the preceding examples or similarly. In the example shown, the arrangement of the transmitters in the antenna column 7a corresponds to that in the example of Figure 1. The same configuration could also be provided in the second column 7b. In the example shown, the configuration is shown in column 7b simply with specular symmetry with respect to the orientation and arrangement of the emitters in the first column 7a. Therefore, above in zone X1, it emits in the first antenna column 7a the first single polarization emitter 103a in the first polarization plane P1 and the third emitter 103b disposed below completely in the third zone X3, in the polarization plane P2 perpendicular to this and on the contrary in the second column 7b the first single polarization emitter 103a disposed above all in the zone X3, emits in the second polarization plane P2 and the third emitter 103b which is located completely below in the zone X3 emits in the foreground of polarization P1. Likewise, both columns can also be exchanged in the example of Figure 7. Naturally, single polarization emitters can also be replaced here by dual polarized emitters, but then operating, as described on the basis of Figure 4, only in the polarization plane that each one has assigned.

The example of figure 8 further shows that in a two-column group antenna as emitters 3 located higher and lower for the upper frequency band Fh, dual polarized emitters 3 can also be used, which as indicated only emit in a polarization plane P1 or P2. Additionally shown in Figure 8 for the battery of two antennas

columns which in this regard can also be again a dual band antenna, as described for a single column dual band antenna based on Figure 5. As rectangles, the emitters generally doubly polarized here for the lowest frequency band Fn, whose distance in the mounting direction may be approximately twice the distance d between the centers of the polarized emitters dually for the upper frequency band Fh. However, basically, the distances d within certain ranges can also vary here and be different.

In the examples it has been described that the emitters are offset from each other in the mounting direction 5. As already indicated, at least individual emitters can be found, that is, single polarized emitters or dual polarized emitters, at least only stripped with a component in the mounting direction, with the consequence that the corresponding emitters or emitting equipment are not arranged apart from each other on an exactly straight assembly line, but also additionally with lateral offset in this regard. But as indicated, for this with a modification of the radiation diagram. When this is also desired, such additional measures may make sense.

We will now refer further to Figure 9, in which the fundamentals of a variant corresponding to the invention relative to Figure 7 are shown.

The exemplary embodiment of Fig. 9 differs from the example of Fig. 7 only in that now the first transmitting equipment 103a located higher in each antenna column, that is, the first transmitting equipment 103a in the left column 7a and the first emitting element 103a that emits in this respect in the perpendicular polarization P2, are assembled in the right column 7b to form a common emitting equipment doubly polarized 103'a. The emitting element 103a, which emits in the first polarization plane P1, is then fed through the corresponding network N2, through which the emitting equipment 3 oriented in the same antenna column 7a in the same plane is also fed of polarization P1 and on the contrary the first emitting equipment 103a in the second column7b, which emits in the second plane of polarization P2, is fed through the network N11, by means of which the emitting elements of the second emitting equipment are also fed together 3 that emit in this plane of polarization P2. The same applies to the third emitting equipment 103b which are found in each case below in the first and second column 7a, 7b, gathered in the variant of Figure 9 also in a dual polarized emitting equipment 103'b and the corresponding polarization planes also again they are fed through the associated networks N1 and N22 respectively.

The preferred antenna batteries described in the context of the invention are characterized in that the same for both polarizations or polarization planes P1, P2 present and generate radiation diagrams of the same type, that is, similar and therefore at least approximately symmetrical, that is, with comparable lobe widths, that is, of comparable size. In addition, since the amount of active emitting elements in each polarization plane is the same, the gain that can be achieved for each polarization plane is comparable, therefore being in the same order of magnitude or value.
