Definitions
- the invention relates to a dual polarized. dipole antenna according to the preamble of claim 1.
- the antenna becomes a polarization alignment of ⁇ 45 ° is used.
- a common antenna housing in front of a reflector are usually in the vertical direction several such dipole squares for transmission in one frequency range and for example between two such vertically arranged one above the other Dipole squares another dipole square for transmission arranged in the other frequency range.
- the predominant horizontal half-width the antenna is 65 °.
- the orientation of the dipoles is + 45 ° or -45 °. Resulting from this arises a so-called dipole square.
- the two horizontal radiation diagrams of + 45 ° and -45 ° polarizations should be as congruent as possible be aligned. A deviation is called a tracking error designated.
- the object of the present invention is therefore that To overcome disadvantages according to the prior art and to create an improved dual polarized antenna.
- Another advantage is that the whole Cable expenditure compared to conventional antenna devices can be reduced.
- the surprising solution according to the invention lies in this justifies that the two opposite parallel dipoles of a dipole square, with the same Radiate or receive polarization, not in parallel or with balanced cables or with separate ones Cables are fed in, but that the feed done only with respect to a dipole and from the feed point then a coaxial one at one dipole Connection cable for Infeed on the opposite second, parallel Dipole is provided.
- This connecting line shows an electrically effective length such that each parallel dipoles of a corresponding dipole square are excited in phase.
- the Connection line of an electrically effective length of at least approximately ⁇ or an integer multiple of this with regard to the frequency band range to be transmitted, especially in relation to the center frequency, on.
- the third example uses a two-wire connection line with a length ⁇ to the in phase Supply used.
- This prior publication concerns but only a completely symmetrical special case two dipoles arranged parallel to each other. There can neither the problem underlying the invention Squint may occur, nor could such a Measure a solution to this can be expected.
- the antenna according to the invention is a nested group antenna with orthogonal polarization with two dipoles or with two dipole pairs, the arranged rotated relative to the vertical or horizontal are, namely preferably in a + 45 ° or one -45 ° angle.
- the individual diagrams of the various Polarization is not congruent, but they are mirrored to the vertical plane.
- the electrical length of the connecting cable a wavelength ⁇ or an integer Multiples thereof, based on the center frequency to be transmitted, equivalent.
- the tracking behavior according to the requirements can be preset differently. This can be done in one preferred embodiment of the invention that, for example, the feed from the feed cable coming only on the same side with the corresponding polarization-oriented dipoles and for all dipoles in the same way starting from there Connection cable to the opposite dipole to lead.
- a change in tracking behavior or size the synchronization of the radiation diagrams or a deviation of the two radiation diagrams for the two polarizations can also be realized in that for example of four dipole squares arranged one above the other the feed in terms of parallel to each other arranged dipoles with three dipole squares each related to the dipole on the left and only with respect of a dipole square only with respect to the parallel one Dipoles on the right.
- the antenna can be different if necessary selectable series feed to compensate for the Frequency dependence of the radiation diagrams and for compensation of tracking error, which is completely surprising and is not obvious.
- the solution according to the invention also offers the further one Advantage that only one with a correspondingly large size Cross section of two feed cables dipoles offset by 90 ° is provided, and that only one of these two dipoles with a thinner one Cross section equipped connecting cable to the each opposite dipole of a dipole square must become. This will reduce the total cable effort significantly reduced.
- Figure 1 is a schematic top view of a dual polarized Dipole antenna 1 with several first dipole squares 3 and several second dipole squares 5 are shown.
- the first Dipole squares 1 are used, for example, for transmission in the 900 MHz range.
- the smaller ones second dipole squares 5 are for example for transmission tuned in the 1,800 MHz range.
- All dipole squares 3 and 5 are at 45 ° to the vertical and horizontal inclined and along a vertical Mounting direction 7 one above the other in front of a reflector 9 in a suitable Distance arranged in front of the reflector plate 9 '.
- the dipole squares each comprise two pairs of parallel dipoles 13 and 15 which according to plan view Figure 4 are arranged in the manner of a dipole square. Both dipole pairs 13 'and 13 "and the two dipole pairs 15 'and 15 "are connected to the two symmetry halves 113 'and 113 "or over one Balancing 115 with the two balancing halves 115 'and 115 "worn and held in the shown Embodiment of a foot and anchoring area 21 on the reflector 9 with a vertical and each outward component to the one in front the dipole halves located in the reflector 9.
- a connecting line then goes from this feed point 33 37 from which to the feed point 35 on the opposite Dipole half leads.
- the inner conductor is again with the one dipole half over the connection point 35 'and the outer conductor with the second dipole half electrically connected at 35 ".
- the supply cable is also connected via the Bore 23 on one arm or in one arm the symmetry, 113 'or 113 "(if this, for example is designed as a waveguide or hollow support) in Layed inside and led to the entry point 33 where the outer conductor is electrically connected to one dipole half and the inner conductor at the: connection point of the second dipole half is connected.
- the coaxial connection cable 37 is also on or for example in the second support arm 113 'or 113 "of the corresponding symmetry 113 from the feed point 33 at the one dipole returned towards the reflector plate 9 'and in the possibly hollow support arm of the opposite Balancing 113 of the opposite dipole 13 ' whose top feed point 35 out.
- the length of the connecting cable should be ⁇ or one integer multiples thereof, based on the one to be transmitted Frequency range, especially the center frequency range, be.
- a separate power cable or a Corresponding separate connecting cable the feed on the two in the embodiment of Figure 4 and 5 dipoles 15 and 115 offset by 90 °.
- 6 and 7 are two examples of 8 once Dipole squares arranged one above the other in 45 ° orientation shown to achieve a very specific value a different feed once for tracking. regarding the one on the left or the one on the right show lying dipoles. The same applies to the embodiment according to Figure 7, which 6 one above the other arranged dipole squares in 45 ° orientation shows. there starting from a main feed line 27 via subsequent distributors and taps, the feed for the different dual polarized dipole squares realized. 6 and 7 is the reflector plate not included.
