Definitions
- the invention relates to a dual polarized dipole radiator according to the preamble of claim 1.
- Dual-polarized antennas usually have as primary radiators Dipole emitters, patch emitters or slit emitters. With the dipole radiators come essentially as structures the dipole square, consisting of four single dipoles, and a cross dipole arrangement for use. This means that the radiators mentioned can be used both horizontally and also vertically and with a polarization orientation in be operated at an angle of ⁇ 45 °.
- Dipole emitters patch emitters or slit emitters.
- the radiators mentioned can be used both horizontally and also vertically and with a polarization orientation in be operated at an angle of ⁇ 45 °.
- X-polarized antenna as is known in principle from DE 196 27 015 is.
- Another disadvantage is particularly with ⁇ 45 ° polarized Dipole antennas in that a relatively high coupling with an array arrangement consisting of dipole squares can be determined. This relatively high coupling especially affects antennas with tunable Phase position of the dipoles disturbing (adjustable electrical down tilt).
- the dual polarized dipole radiators according to the invention are compared to conventional solutions, so that the dipole emitter according to the invention on the one hand more cost-effective are producible.
- Dipole radiator in electrical terms like a Cross dipole act, in mechanical design terms in contrast, they are more like a dipole square.
- the antenna in the horizontal and / or vertical direction polarized radiate or receive, i.e. in electrical aspect with the alignment of the cross dipole its electrical dipole axes in the horizontal and vertical directions should be in a constructive sense more like a dipole square with the individual modules Dipole components are aligned in ⁇ 45 ° direction.
- each of the four Dipole is fed through a balanced line, and due to the special type of interconnection neighboring dipole halves orthogonal to each other two neighboring dipoles are excited in phase.
- This symmetrical or at least essentially or approximately symmetrical feed lines consist of two Line halves, which are considered individually compared to one fictitious zero potential represent an unbalanced line.
- the interconnection of the unbalanced cable halves takes place according to the invention in such a way that the two adjacent and orthogonal to each other aligned dipole halves leading two line halves are electrically connected to each other.
- the feed the resulting total radiator takes place via Cross.
- the respective line half leading to the dipole symmetrical feed line as a mechanical holder of the Dipole half formed and this is or ends preferably at the same distance above the reflector, in which the dipole itself is attached over the reflector.
- this line can also be part of the resulting Cross dipoles are conceived by the antiphase
- currents on the line halves do not radiate them or only slightly with. So here it is desired cancellation of the radiation effect and thus a better bundling of the dipoles. So it's totally surprising that then through the appropriate interconnection on the one hand a radiation of the polarization lying in a ⁇ 45 ° plane is achieved and on the other hand broadband high decoupling is achieved.
- the symmetrical feed lines are preferred with their both asymmetrical line halves arranged so that this is a top view of a radiator arrangement assume an approximately central symmetry and to the two connection points of two in axial extension of dipole halves to lead.
- These feed lines can also run completely differently to be ordered.
- this line halves of the symmetrical Feed line from the back of a reflector plate can pass through this, the line halves for example approximately perpendicular to the plane of the Reflector sheet directly to the ones above Connection points of each in an axial extension lead dipole halves.
- the Holding device for the dipole halves of those with the Dipole halves related line halves be completely separate.
- the two half dipole components that are perpendicular to each other are usually arranged so that each with their free ends on a common one Point of intersection of the corner points of a square forms.
- the components of the dipole halves do not have to be here have a constructive connection, but can.
- the components can be metallic or through Use of isolators mentioned in the key points of the Squares sit, be connected.
- the dipole radiator 1 known from the prior art 1 is constructed such that - meanwhile dipoles 3 linear polarizations with an angle of + 45 ° and -45 ° received or related to the vertical or horizontal can broadcast.
- Such antenna or antenna array are also called X-polarized antennas or antenna arrays designated.
- Figure 1 are each from the axial center 5 First dipole 3 "in a staggered antenna arrangement -45 ° alignment and second dipoles 3 'in a + 45 ° alignment intended.
- Figure 1 is indicated schematically that the two opposite Dipoles 3 'or 3 "combined to form a double dipole are.
- the dipole emitter shown in Figure 2 works - what will be discussed in more detail below - in electrical Regards as one with a polarization of ⁇ 45 ° radiating dipole, e.g. like a cross dipole.
- the in electrical considerations as cross dipole 3 radiators is shown in dashed lines in Figure 2. This one in electrical Regarding cross dipole with 3 radiators a ⁇ 45 ° orientation with respect to the horizontal by an electrical dipole 3 '(inclined in + 45 ° direction) and a perpendicular dipole 3 "(with -45 ° opposite the horizontal inclined).
- the next dipole half turns clockwise accordingly 3 "b des in electrical terms with -45 ° orientation provided electrical dipoles 3 "by the two Half dipole components 111b and 112a are formed.
- the in extension second dipole half formed to the dipole half 3'a 3'b is the two half dipole components 112b, 113a and the fourth dipole half 3 "a through the two half dipole components 113b, 114a formed in an analogous manner.
- the semi-dipole components arranged as a dipole square are now each through a symmetrical feed line 115, 116, 117 and 118 fed.
- a symmetrical feed line 115, 116, 117 and 118 fed For example the two half dipole components 114b and 111a, that is, the neighboring ones orthogonal to each other aligned half dipole components, via a common Infeed point, here infeed point 15 'in phase excited.
- the one belonging to these half dipole components 114b, 111a Connection lines consist of two Line halves 118b and 115a, which are considered individually compared to a fictitious zero potential 20 an asymmetrical Represent line.
- the feed line is designed in such a way that the mechanical fixation of the dipoles, i.e. the half dipole components, takes over.

- symmetrical line 115 one unbalanced line half 115a the dipole half 111a and that of line half 115a electrically separated, preferably in parallel extending second line half 115b the second dipole half 111b.
- the resulting total radiator now works due to the in-phase excitation of the semi-dipole components 114b, 111a or the half dipole components 111b and 112a or 112b and 113a or 113b and 114a electrical like a cross dipole. Due to the specific arrangement of the Line halves, each parallel at a short distance are arranged to each other and the current in phase opposition flows, it is ensured that the pipe halves itself do not make any significant contribution to radiation, so every radiation is extinguished by overlapping.
- the basic structure in top view of the radiator arrangement according to FIG. 2 shows that the radiator module has an in Top view has fourfold symmetry.
- Two right angles mutually symmetrical axes are represented by the symmetrical lines 115 and 117 or 112 and 118 formed, the third and fourth axis of symmetry in Top view of the radiator arrangement according to FIG. 2 45 ° twisted and through which is in electrical Resulting dipoles 3 'and 3 "are formed.
- the supply takes place crosswise between the feed points 5 ', 5 "or 15', 15".
- the mentioned electrical lead halves 115a to 118b arranged symmetrically to each other in pairs, i.e. the neighboring electrical line halves each two adjacent half dipole components parallel to each other at a comparatively small distance, this distance preferably the distance 55 between the ends of the associated ends to be assigned to each other Dipole halves corresponds to, for example, that Distance between the mutually facing ends of the dipole halves 111a, 111b etc.
