Definitions
- the invention relates to a combination antenna for receiving terrestrial and satellite signals according to the preamble of claim 1.
- the combination antennas should also be suitable for receiving terrestrial signals.
- the corresponding systems are also known in the technical field under the term SDARS services which transmit in the 2.3 GHz range.
- the satellite signals are transmitted in a circularly polarized manner.
- a special antenna system has become known on the USA market which contains a cross dipole which is formed from a flat material and thereby forms four quadrants which are separated from one another by the dipole walls. A separate, vertically extending monopole is then arranged in each quadrant, via which the terrestrially broadcast, vertically polarized signals can be received.
- the total expenditure of the antenna is considerable, however, since above all appropriate feed networks are required to feed the cross dipole and the four monopoles.
- the combination antenna according to the invention comprises a monopoly on the one hand for receiving the terrestrial, especially vertically polarized signals.
- the antenna according to the invention comprises a patch antenna known per se.
- patch antennas achieve their optimal function in the zenith, ie at 90 ° elevation.
- the antenna gain then reaches its maximum, the axis ratio of circularly polarized patch antennas conversely reaching a minimum.
- a monopole extending in the form of a vertical rod is used as a radiator for receiving terrestrial signals, as is known per se from the prior art.
- an inverted F antenna for example made of wire or the like, is also preferably Chen used, which can be arranged on a substrate, such as a circuit board.
- a printed circuit can also be used as a monopoly, for example on a printed circuit board, which can be arranged vertically on a substrate in the form of a further printed circuit board.
- a strip conductor can be formed for the monopoly, which can also be S-shaped or meandering in the manner of a rectangular pulse to reduce the overall height.
- an antenna arrangement with a cavity is used, in the top side of which an annular slot is provided, for example in the form of a metal plate.
- the ring slot acts like a monopoly.
- the cavity ie the cavity located below the slot, is preferably filled with a dielectric, for example glass, ceramic or the like. Since the dielectric constant ⁇ R of glass, for example, has a value around 9 and that of ceramic has a value around 20 to 30, this leads to a reduction in the cavity to a third when using glass or a fifth when using ceramic. This means that very low-profile combination antennas for receiving the SDARS services can be implemented.
- a dielectric for example glass, ceramic or the like. Since the dielectric constant ⁇ R of glass, for example, has a value around 9 and that of ceramic has a value around 20 to 30, this leads to a reduction in the cavity to a third when using glass or a fifth when using ceramic. This means that very low-profile combination antennas for receiving the SDARS services can be implemented.
- Figure 1 is a schematic side view of an antenna according to the invention.
- FIG. 2 shows a plan view of the exemplary embodiment of the antenna according to the invention shown in FIG. 1;
- FIG. 3 a top view comparable to FIG. 2 with regard to a slightly modified exemplary embodiment
- FIG. 4 shows another modified exemplary embodiment with respect to an inverted F antenna as a monopoly
- FIG. 5 a stripline monopole antenna in a further modified exemplary embodiment
- Figure 6 another modified embodiment with respect to a monopoly
- FIG. 7 shows a plan view of a further modified embodiment of a combination antenna with an annular slot instead of a monopole radiator.
- FIG. 8 a cross-sectional illustration with regard to of the embodiment of Figure 7.
- a combination antenna 5 for receiving SDARS services in the USA which typically radiates in the 2.3 GHz range, is constructed on a substrate 1, preferably in the form of a printed circuit board 1 ′′.
- a monopoly 7 i.e. a rod-shaped monopoly 7a is provided in the exemplary embodiment shown.
- a patch antenna 9 is built on the side of the substrate 1 next to it. Both radiators 7 and 9 are fed in a known manner.
- the patch antenna 9 preferably consists of a ceramic patch antenna 9 '. Since the mechanical size of the patch antenna 9 depends on the resonance frequency on the one hand and on the dielectric constant of the material used on the other hand, a microwave ceramic is generally used. Since circularly polarized electromagnetic waves in the 2.3 GHz range are to be received by means of the patch antenna and the mechanical size of the patch antenna depends on the resonance frequency, as mentioned, a comparatively small patch antenna 9 results and it is surprising that by means of such a patch antenna 9 the high demands in accordance with the usual system specifications of service providers can be met, according to which the antenna gain should be greater than 3 dBic in the elevation range from 25 ° to 90 °.
- FIG. 2 shows the top view of the antenna arrangement according to FIG. 1. It can be seen that the monopole is arranged on a vertical central longitudinal plane 13 which is parallel to the side boundaries 14 of the patch antenna 9, which is square in plan view, or runs vertically.
- the patch antenna can also be arranged rotated by 45 ° with respect to the exemplary embodiment according to FIGS. 1 and 2, so that the monopole 7, which is rod-shaped and extends vertically in one example, in the exemplary embodiment shown vertical center plane of symmetry 13, which runs diagonally through the patch antenna 9.
- an inverted F antenna 7b can be used instead of a rod-shaped monopole 7, one leg 14 of which is set to ground on the substrate 1, 1 ', whereas via an offset feed line 15 the feed-in to the monopoly takes place with high resistance.
- a monopole 7c in the manner of a strip conductor can also be used according to FIG. 5, which is applied to a substrate, for example a further separate printed circuit board 19.
- the strip conductor 21 can be arranged in a meandering manner or in the manner of a rectangular pulse on the substrate or the printed circuit board 19.
- a monopole 7d is used, in which the rod-shaped monopole is designed as a coil former 23 at the end remote from the printed circuit board 1 '.
- a combination antenna is used which has a cavity 27 which is formed by a housing 29 delimiting the cavity 27.
- the housing 29 can preferably be provided with a metallic surface.
- annular slot 33 is made in the corresponding housing wall 29 '.
- the patch antenna 9 is positioned on the top 31, i.e. on the upper housing wall 29 ', and is fed in a known manner.
- the ring slot 33 runs in the upper housing wall 29 ', the radiation pattern of which is comparable to a monopoly.
- the height ⁇ / 4 corresponds to the operating center frequency. So if the antenna is in 2.3
- this height can be effectively reduced by filling the cavity 27 by means of a dielectric.
- Glass or ceramic, for example, are suitable as a suitable dielectric.
- the mechanical dimensions can be significantly reduced.
- the present invention is, in a completely surprising manner, also suitable for receiving programs which are broadcast via satellites that are comparatively low above the horizon. It is completely surprising that such a high antenna gain can be achieved with a patch antenna if the satellite signals are at an angle of less than 50 °, in particular also less than 40 ° or even less than 30 °, namely in particular also by 25 ° , are broadcast.
