Definitions
- the present invention relates to the field of antenna technology. It relates to a dual-band antenna according to the preamble of claim 1.
- Such a dual band antenna is e.g. known from US-A-6,239,750.
- UMTS Universal Mobile Telecommunication System
- a new cellular network is required for applications based on this standard. Part of this network are antennas which, because the UMTS standard is based on new frequency ranges for sending and receiving, must also be newly developed.
- the previous mobile radio networks based on the conventional GSM 900/1800 standard, as well as a large number of other networks based on other standards, will continue to be operated in parallel with the newly created UMTS standard for a period that is not yet foreseeable.
- network operators are interested in using existing antenna locations for the existing networks as well as integrating them into the new UMTS network.
- Dual polarized (dual slant) antennas for base stations which consist of an array of dual polarized single radiators (single antennas), have long been known. known.
- Dual-polarized broadband antennas are also known, which are composed of an array of identical dual-polarized single radiators, which are tuned to broadband frequencies of 1710-2170 MHz, so that the antenna covers both the GSM 1800 and the UMTS band .
- a particularly effective single radiator of this type, which has been tried and tested in practice, is known from WO-A1-01/76010 by the applicant.
- dual-polarized antennas are known which cover the GSM-900 and the GSM-1800 or GSM-1800 / UMTS band and which consist of an array of appropriately tuned dual-polarized single radiators.
- WO-A2-99 / 59223 discloses a dual band antenna in which a first linear array of patch radiators for the GSM band (860-970 MHz) with a second linear array of cross dipoles for the PCN band (1710-1880 MHz ) is combined, the cross dipoles being arranged between the patch radiators in a first embodiment and directly above the patch radiators in a second embodiment.
- the essence of the invention is first and second individual antennas in one linear periodic arrangement (array) to be arranged, wherein the second individual antennas are arranged alternately between the first and above the first individual antennas, and wherein the first and second individual antennas are each designed as patch radiators, each in a rectangular, electrically conductive, open at the top Box arranged printed board and several patch plates include, which are arranged above the printed board and parallel to the printed board at a distance above one another.
- the peculiarity of this arrangement is that here individual patch plates for different frequency bands are not arranged one above the other and next to each other, but that each of the patch radiators with its printed circuit board arranged in the box is used in the array.
- the patch plates of an individual antenna are preferably kept at a distance from one another and from the printed circuit board by means of electrically insulating spacer elements.
- a preferred embodiment of the invention is characterized in that in the second individual antennas three patch plates are arranged one above the other, that in the first individual antennas two patch plates are arranged one above the other and that in the first individual antennas in each case instead of a third patch plate a second single antenna with its box is arranged at a distance above the top of the two patch plates.
- the second individual antenna is thus at the same time an integral part of the first individual antenna over which it is placed.
- the first and second individual antennas are preferably arranged above a common base plate extending in the longitudinal direction of the antenna.
- the base plate can be non-metallic.
- the base plate can also be designed as a (metallic) reflector.
- the first individual antennas are designed to cover the frequency range from 806-960 MHz and the second individual antennas are designed to cover the frequency range from 1710-2170 MHz.
- N integer> 0.
- a proven design results for N 7.
- FIG. 1 is a top view of a dual-band antenna according to a preferred embodiment of the invention with the cover removed;
- Fig. 2 shows the section through the two adjacent first and second
- FIGS. 1 and 2 shows the top of the printed circuit board of a first individual antenna from FIGS. 1 and 2;
- FIGS. 1 and 2 shows the underside of the printed circuit board of a first individual antenna from FIGS. 1 and 2;
- FIG. 1 and 2; and 6 shows the underside of the printed circuit board of a second individual antenna from FIG.
- the dual-band antenna 10 contains, in an elongated housing 11, a linear periodic arrangement (array) of first individual antennas (single radiators) 14 and second individual antennas (single radiators) 15 and 16 over an elongated base plate 12 which fills the entire housing 11, but the width of the base plate can be also be reduced to the width of the individual antennas.
- the base plate 12 can be non-metallic. However, it can also be metallic and then act as a reflector. The forward / reverse ratio is optimized by arranging the individual antennas 14, 15, 16 above a reflector.
- the first individual antennas 14 and part of the second individual antennas 15 are arranged alternately in the linear array.
- the remaining second individual antennas 16 are placed concentrically above the first individual antennas 14 (see also FIG. 2).
- the distance between the second individual antennas 15, 16 is in this way half as large as the distance between the first individual antennas 14. With a minimum size of the second and first individual radiators, this results in a distance of 0.78 times or 0.87. times the wavelength - in each case based on the band center frequency - between the first and second individual antennas.
- the basic structure of the first and second individual antennas 14, 15 and 16 can best be explained using the cross-sectional illustration of FIG. 2:
- the structure of the second individual antennas 15 and 16 is largely identical.
- a printed circuit board 22 and 27 is arranged in a square, upwardly open box 21, 26 made of sheet metal, parallel to the floor at a distance from the floor of the box 21, 26, the configuration of which is on both sides and ration is shown in Figs. 5 and 6.
- Three patch plates 23, 24, 25 and 28, 29, 30 are provided above the printed circuit board 22, 27 parallel to the printed circuit board 22, 27 at different distances from one another, which are excited by the printed circuit board 22, 27 and couple with the electromagnetic radiation.
- the second individual antennas 15, 16 are provided and adjusted for the frequency band from 1710-2170 MHz (GSM 1800, UMTS) (UMTS radiator). Their outer dimensions and patch panel spacing are therefore smaller than in the first individual antennas 14.
- the UMTS radiators 15 and 16 are each offset in height above the base plate 12 (FIG. 2).
- Two patch plates 19 and 20, which are excited by the printed circuit board 18 and couple with the electromagnetic radiation, are provided above the printed circuit board 18 parallel to the test board 18 at different distances from one another.
- a second individual antenna 16 with its box 21 is arranged at a distance above the two patch plates 19, 20.
- the printed circuit boards 18 of the first individual antennas 14 and 22 and 27 of the second individual antennas 16 and 15 have different conductor tracks 31, 32 and 34, 35 on their upper side according to FIGS. 3 and 5.
- Ground surfaces 33 and 36 are provided on the undersides, in which slot-shaped conductor structures 37, 38 and 39, 40 are formed in a crossed arrangement.
- the individual antennas 14, 15, 16 can be supplied by any network.
- the box 21 of the UMTS radiator (single antenna 16) on the 900 MHz radiator (single antenna 14) has an effect comparable to that of a third patch plate, ie the bandwidth is also increased by the UMTS radiator (due to capacitive coupling between of the UMTS box 21 and the two patch plates 19, 20 of the 900 MHz box or the slot structure (conductor structure 37, 38) of the printed circuit board 18, additional resonance frequencies are excited which lead to an expansion of the bandwidth).
- the base plate 12 As a reflector and thus caused the radiation direction to be specified.
- the box 17, 26, which encloses the individual antenna already fulfills this task.
- the reflector plate serves on the one hand as a base plate 12 for mounting the boxes 1, 26 and on the other hand the forward / reverse ratio is optimized by the distance of a box above such a reflector plate.
- the optimal distance between the individual antennas 14 and 15, 16 in the array of the dual band antenna 10 is 0.7 times the wavelength of the respective band. It follows that the distance between the UMTS radiators 15, 16 has to be approximately half as large as that of the 900 MHz radiator 14.
- the configuration follows this rule in the present case.
- the construction begins and ends with a 900 MHz radiator 14. In this way, a maximum number of 900 MHz radiators 14 as well as UMTS radiators 15, 16 can be accommodated. This allows the gain to be maximized for a given antenna length and the radiation diagrams to be optimized. In the example in FIG. 1, a total of seven 900 MHz radiators 14 and thirteen UMTS radiators 15, 16 are provided in the array.
- N integer> 0.
- N integer> 0.
- the individual antennas are patch radiators and have a printed circuit board arranged in a box with several lying above the printed circuit board
- the period of the UMTS radiators is half as long as the period of the 900 MHz radiators.
- the UMTS emitters are arranged between and above the 900 MHz emitters. - This results in an "increased" arrangement of radiators, in which the
- Box of the UMTS radiator is an integral part of the 900 MHz radiator and contributes to its adaptation.
- the UMTS emitters are arranged at different heights, whereby phase differences that occur are compensated for by different lengths of the feed lines.
- Connection side 15.16 single antenna (patch radiator), 21.26 box, 22.27 printed circuit board, 23.28 patch panel, 24.29 patch panel, 30 patch panel, 32 conductor track
