Definitions
- the invention relates to an antenna with at least one dipole or a dipole-like radiator arrangement according to the preamble of claim 1.
- Dipole radiators have become known, for example, from the prior publications DE 197 22 742 A and DE 196 27 015 A.
- the dipole emitters can consist of a normal dipole structure or, for example, of a cross dipole arrangement or a dipole square etc.
- a so-called vector cross dipole is known from the prior publication WO 00/39894.
- the structure appears to be comparable to a dipole square.
- a cross-dipole structure is ultimately created, so that the antenna element formed in this way can radiate and receive in two mutually perpendicular polarizations. All of these previous publications as well as the other di- In this respect, pole structures are also made the content of the present application.
- the object of the present invention is to provide an improved antenna with at least one dipole or dipole-like radiator which has characteristic electrical characteristics which are clearly reproducible compared to conventional antennas and which may even be easier to install.
- the present invention provides that a radiator element of this type be capacitively coupled to the reflector plate.
- a non-conductive element in particular a dielectric
- an electrically reproducible positioning of the emitter on the reflector plate can be achieved, since the intermodulation problems that may occur under the prior art are avoided.
- the dipole or dipole-like emitter elements are mechanically attached to the reflector sheet according to the prior art, these were usually attached to the reflector sheet by means of screws or other connecting mechanisms, which resulted in different contact conditions depending on the mounting accuracy, with the result that intermodulation problems could occur that expressed themselves differently.
- the dipoles or dipole-like emitters are placed on the reflector plate and fastened by screwing in one or more screws from the rear of the reflector.
- the contact pressure also decreases due to the effects of heat, for example, the contact conditions change, as a result of which the performance of such an antenna element decreases significantly.
- a dipole or dipole-like radiator with the actually radiating dipole halves and its symmetry, preferably integrally connected to it, is therefore preferably attached to an electrically non-conductive base, which in turn is fixed on the reflector plate.
- an overall electrically conductive dipole or dipole-like radiator including an electrically conductive fastening base, with an insulating intermediate base or a non-conductive intermediate layer now not being used to avoid galvanic contact with the reflector is, but for example the dipole or dipole-like radiator is covered or provided with a plastic layer, that is generally an electrically non-conductive surface, at least in the region of its fastening section located below.
- plastic dipoles can be used according to the invention which have only a partial metallization, in particular are therefore not metallized in their contact and connection area to the reflector.
- the symmetry is preferably understood to be electrically conductive as part of the dipole arrangement.
- a dipole arrangement according to the invention can also be plugged directly onto a circuit board carrier, so that in such a case no additional plastic part is necessary. Feeding could take place directly over the rear of the board structure on which the matching structure is provided.
- the principle explained applies to all types of dipoles, vertical dipoles, X-shaped polarized dipoles (i.e. at a + 45 ° angle to the horizontal) for single-band, dual-band antennas or for dipole structures, in particular square dipole structures, in which several radiators are arranged in each other, which are provided for different frequency bands.
- a suitable punching is provided in the reflector plate, into which the fastening base of the radiating element can, for example, be clipped in, inserted and then rotated into the final fixing position, etc.
- Locking and fastening mechanisms can be used here, such as are known, for example, in the manner of so-called bayonet locks, including all the associated modifications.
- Figure 1 is a schematic perspective view of an embodiment of the invention
- Figure 2 another perspective view of the radiator arrangement according to Figure 1 on a reflector, but from a slightly rear view;
- FIG. 3 is a vertical cross-sectional view through the embodiment of Figures 1 and 2;
- FIG. 4 shows a schematic perspective illustration of an antenna arrangement with three radiators arranged vertically one above the other;
- Figure 5 is a schematic plan view of a reflector with an opening made there for fixing a base of a radiator arrangement shown in Figures 1 to 4.
- Figure 6 a modified embodiment of Figures 1 and 3.
- FIG. 4 shows a schematic representation of an antenna arrangement 1 with a reflector or reflector plate 3.
- the reflector 3 can preferably be provided on its two opposite longitudinal sides 5 with a reflector boundary 3 ', which can be oriented, for example, perpendicular to the plane of the reflector plate 3 or also at an oblique angle deviating from a right angle.
- the radiator or radiator arrangements 7 can consist of single band radiators, dual band radiators, triple band radiators or the like. In today's generation of antennas, dual-band radiators or even triple-band radiators are preferably used, which can also transmit and / or receive in two orthogonally aligned polarizations, and which are preferably at an angle of + 45 ° the horizontal or vertical are aligned.
- radiators with a real dipole structure, in the manner of a cross dipole, a dipole square or in the manner of its so-called vector dipole, as are known, for example, from WO 00/39894. All these types of emitters and modifications are made the content of this application with reference to the above-mentioned prior publications.
- radiator arrangement 11 shows a first radiator arrangement 11 according to the invention on a reflector 3 in greater detail in different representations.
- the radiator arrangement 11 has a structure as known from WO 00/39894 and described in detail in this prior publication. Reference is therefore made in full to the disclosure content of the above publication and made the content of this application. It is known from this that the radiator arrangement 11 according to the exemplary embodiments according to FIGS. 1 to 4 is designed like a dipole square in a schematic plan view, but, due to the specific design, transmits and receives like a cross dipole in electrical terms. In FIG.
- the two polarization directions 12a and 12b are drawn in with respect to a radiator arrangement 11, which are perpendicular to one another and are formed by the diagonal radiator arrangement 11, which is rather square in plan view.
- the structures lying opposite each other by 180 ° according to the emitter arrangement 11 act as dipole halves of two cross-shaped dipoles.
- a dipole-shaped radiator 11 formed in this way is held and mounted on the reflector 3 via the associated symmetry 15.
- the dipole halves 13 and the balancing 15 consist of electrically conductive material, usually metal or metal alloy.
- a base 17 which consists of non-conductive material, for example of plastic, a dielectric, etc.
- the associated base section 15 ′ of the symmetrization 15 is fixed and held via this base 17.
- the base 17 is now in turn anchored in a recess 19 (FIG. 5) in the reflector plate 3.
- the base 17 has, in particular, radially projecting, that is to say laterally projecting, projections 17 ′ and recessed sections 17 ′′, so that the base with this shape can be inserted into a correspondingly shaped recess 19 in the reflector plate the entire arrangement can be rotated, for example, by an angle of approximately 30 ° or 45 ° until the final adjustment position is reached, in which a preferably non-positively secure position of the base 17 with respect to the recess 19 is ensured by the on the back or Underside of the reflector 3 radially protruding projections engage under the corresponding material sections of the reflector, whereas other projections 17 ′ located at the top are parts of the reflector plate reach over from above, thus securely fixing the radiator arrangement 11.
- the base is made of plastic and the symmetry and the radiator arrangement 11 as a whole are separated and insulated from the electrically conductive reflector or reflector plate 3 by the base, this results in a capacitive coupling.
- a circuit board structure 3 'or another substrate 3' can be provided which is non-conductive or is at least non-conductive in the anchoring area of the base or the radiator.
- Conductive structures on the underside of the circuit board in particular large-area conductive structures 31 on the circuit board for producing a reflector or a reflector-like metallization, can be provided on the top or the underside of the substrate or the circuit board 3 ′, but should not be used up to that point Fastening range of the symmetrization of a radiator 7 or a radiator arrangement 11 are sufficient.
- an electrically non-conductive base can be dispensed with.
- the radiator with its radiator structure can be directly on the non-conductive the substrate or the non-conductive board structure are placed and anchored.
- the substrate can preferably be formed from a circuit board, on the rear side of which the electrically conductive matching structures are formed, without the symmetry being galvanically coupled.
- radiator including the symmetry
- base section 15 ′ of the radiator arrangement being coated with an electrically non-conductive material, plastic or a dielectric in this exemplary embodiment, and above this Reflector plate is fixed.
- This also ensures a capacitive, that is to say galvanically, electrically non-conductive connection on the reflector plate.
- the radiator arrangement or at least the symmetry can be formed entirely or in large parts from non-conductive material, which is then coated with a conductive structure, in particular a metallizing layer. Excluded from this metallically conductive surface structure are only those anchoring sections with which the radiator 11 thus formed is mounted, for example, on a conductive reflector 3 in order to avoid a galvanic-electrical connection.
