Definitions
- the present invention relates to a device for transmitting or radiating high-frequency waves.
- Devices for radiating electromagnetic waves such as, for example, planar antenna elements, which are excited via a slot to vibrate and thus to radiate high-frequency waves, are widely used, for example, in directional radio, satellite radio or radar technology. They are preferably used in the microwave range, since small sizes and thus simple implementations are possible at low cost.
- FIG. 6A A conventional planar antenna device is shown with reference to FIG. 6A, in which a slot coupling is excited via a microstrip line (MSL) 10.
- MSL microstrip line
- this microstrip line 10 has an abrupt end 10 'and thus forms an idle line.
- a slot 14 is arranged in a ground area 12 separated by a substrate 11, perpendicular to the microstrip line 10, through which a through-hole, ie a coupling, of the at this point maximum magnetic field takes place.
- FIG. 6B shows the cross-sectional view of the device according to FIG. 6A in plan view.
- microstrip line substrates 11 become very thin at higher frequencies, e.g. 254 ⁇ m for a short-range radar application
- SRR at 24GHz
- these substrates 11 must be connected to a rigid carrier material 18, as shown in FIG. 7A.
- This carrier material 18 is not suitable for high frequencies for reasons of cost.
- the carrier material 18 is attached above the ground surface 12 with a fixed connection to the latter, a costly recess 19 in the carrier material 18 being necessary to ensure the function of the antenna in the area of the coupling slot 14 or the radiating element 16, so that the radiating element is via the coupling slot 14 16 can be coupled electromagnetically.
- Another conventional embodiment of a slot-coupled antenna uses a so-called "buried", signal-carrying line 10 with an abrupt line end 10 ', which is in the form of a so-called
- Triplate line is executed and in turn also excites the single radiator 16 via a slot 14 for radiation.
- the signal line 10 is arranged essentially plane-parallel between two ground surfaces 12, 13, in which 8A or FIG. 8B, the microstrip line 10 is closer to one of the two ground surfaces 12, 13, which leads to an antenna arrangement with asymmetrical triplate feed.
- the symmetrical or asymmetrical triplate arrangement has the advantage that larger line elements in a lower layer than buried structures can be hidden, so that space can be saved.
- a buried feed network does not have a negative influence on the radiation characteristic of such an arrangement, in contrast to, in particular at higher frequencies, "open" distribution or feed networks which contribute significantly to parasitic radiation.
- Another advantage is the possibility of providing multilayer or multilayer arrangements that are easy to manufacture, since their individual layers or individual layers have good high-frequency properties and carry the respective line structures to be buried. If suitable layer or substrate materials, such as ceramics, are used, the connection to an additional mechanical support can be dispensed with, since the multilayer arrangement over has sufficient structural stability.
- LTCC low te perature cofired ceramic
- the antenna arrangement just described with reference to FIGS. 8A and 8B has the disadvantage that the detachment of waves is greatly promoted at an abrupt end 10 ′ of the signal-carrying, central line 10 of the triplate structure.
- a not inconsiderable power component of the signal can then undesirably spread in the substrate material 11, for example in the form of parallel plate modes or waveguide modes.
- the multilayer arrangement is laterally encased in a metallic support or housing, the excitation of waveguide modes is additionally favored.
- the propagation of waveguide modes is determined by their cut-off frequency f g , the value of which depends directly on the distances between the bounding metallic walls.
- connection applies that the cut-off frequency f g of a waveguide mode is shifted to lower frequencies if the distance between the electrically conductive, for example metallic, walls is increased.
- the number of modes that can be propagated in a specific frequency band is constantly increasing. If such modes are now excited in the substrate 11 by idling line ends, on the one hand the power emitted via the radiator element 16 is reduced and on the other hand coupling with other circuit parts within the substrate 11, for example further antenna elements, is favored, which adversely affects the antenna characteristics and the overall system behavior impact.
- the device according to the invention for transmitting or radiating high-frequency waves with the features of claim 1 has the advantage over the known approach that the excitation of substrate or waveguide modes in a slot-coupled antenna arrangement. symmetrical or asymmetrical triplate line prevented or to one for the behavior of the antenna or the
- the device according to the invention makes it possible to provide a cost-effective improvement in the function of the antenna, since the suppression of the excitation of substrate or waveguide modes described contributes to improving the efficiency of the antenna and thus to improving the system behavior.
- the idea on which the present invention is based essentially consists in providing a removal measure in the area of the signal line as well as in the area of the coupling slot and to adapt its dimensions to both requirements.
- a device for transmitting or radiating high-frequency waves which has a microstrip line with an end in a substrate for transmitting high-frequency useful signals, a first ground plane and a second ground plane, which are provided on opposite sides of the microstrip line, for shielding the microstrip line, provides an opening in the first ground plane at a predetermined distance from the end of the strip line for coupling out a high-frequency signal, a through-contact device for conductive connection of the first ground plane to the second ground plane in the Has periphery of the microstrip line for shielding the same (e.g.
- vias provides a planar coupling device for receiving and transmitting the high-frequency useful signal
- the through-contacting device being structured and / or dimensioned such that for a given frequency of the useful signal there are essentially no capable of propagation or resonance Waveguide modes occur in the substrate.
- the structure of the through-contacting device expands in the area of the coupling opening. This has the advantage that the coupling to a radiation element (patch) is not impeded by the shielding through-contacting device in the region of the coupling opening.
- a distance a between opposite plated-through devices in the area of the microstrip line is smaller than the quotient from c 0 + ⁇ 2 - f - “J ⁇ r j, where Co for the speed of light in a vacuum, ⁇ r for the dielectric permitti - vity of the substrate and f stands for the frequency of a useful signal.
- This advantageously prevents a first propagable waveguide mode of a rectangular waveguide, which is approximately present here (TE ⁇ o _ mode), from forming a cross-sectional mode with a transverse electrical (TE) field.
- C 0 stands for the speed of light in a vacuum
- ⁇ r for the dielectric permittivity of the substrate
- f res for a resonance frequency of a stimulable waveguide mode, which is to be provided above a useful signal frequency band.
- the resonance frequency is at a greater distance than about a few percent above the useful signal frequency band. In this way, a safe avoidance of resonance phenomena is guaranteed.
- the device for useful signals is dimensioned in a frequency band between 20 GHz and 30 GHz.
- the device is suitable for use in an SRR (short-range radar) application.
- the through-contacting device consists of discrete through-contacting elements which are arranged laterally adjacent to one another, preferably forming an electromagnetic shielding wall. This has the advantage of good shielding in the case of through-contacting elements which can be produced inexpensively, the choice of the distance depending on the frequency.
- the discrete via elements are round and / or cylindrical. This can ensure simple manufacture.
- the through-contacting device forms a continuous wall.
- This offers the advantage of a closed shielding device, for example in the form of a metallic layer, which permits almost no electromagnetic coupling or decoupling.
- the through-contacting device is provided continuously in the region longitudinally adjacent to the end of the strip line. Complete shielding of the stripline is advantageous here.
- the via device is provided with a gap in the region longitudinally adjacent to the end of the strip line.
- the microstrip line is arranged closer to the ground surface provided with the coupling opening than to the other ground surface in the substrate or vice versa. This has the advantage of an asymmetrical structure, which e.g. when a further microstrip line is connected via the coupling opening is required.
- the microstrip line is arranged approximately equidistant between the ground surface provided with the coupling opening and the other ground surface in the substrate. This provides the advantage of a simple arrangement.
- the planar coupling device forms a second microstrip line in another plane, which is provided with galvanic isolation for the electromagnetic coupling of this further microstrip line.
- the two microstrip lines are of essentially the same design and overlap in the longitudinal direction by a twice the predetermined distance, which preferably corresponds to approximately half the wavelength of the coupling useful signal. This ensures maximum electromagnetic coupling between the two microstrip lines.
- Coupling opening parallel to the ground surfaces provided slot-like and / or rectangular. This enables a simple, inexpensive coupling opening layout to be produced in the ground plane and offers good coupling in and out through the slot.

- FIG. 1 shows a schematic oblique view of a slot-coupled emitting device for explaining a first embodiment of the present invention.
- a microstrip line 10 is embedded in a substrate 11.
- This substrate is preferably radio frequency compatible and has e.g. a low temperature cofired ceramic (LTCC), which has good dielectric properties with low attenuation.
- LTCC low temperature cofired ceramic
- the lower end of the arrangement shown is formed by a second ground surface 13 which, like the first ground surface, consists of an electrically conductive material, preferably comprising a metal.
- the first ground surface 12 has a coupling opening 14, which is preferably rectangular and / or slot-shaped, and which has a predetermined distance d (not shown) with respect to an abrupt end 10 'of the microstrip line 10.
- This coupling opening 14 is aligned in the Y direction in the center of the strip line 10 or the end of the strip line 10 'and at right angles thereto, similar to a cross.
- the predetermined distance in the X direction between the slot opening 14 and the end 10 'of the stripline 10 corresponds approximately to a quarter of the line wavelength, ie ⁇ / 4, of the useful signal f transmitted on the stripline 10, which in this example has a bandwidth of the frequency band F in the range between 20 GHz and 30 GHz.
- a through-contacting device 15 is provided, which according to the present embodiment consists of individual through-contacting elements 15 '.
- the individual plated-through elements 15 ' are preferably of approximately round and / or cylindrical design and provide a shielding device similar to a gallery wall.
- a planar coupling device 16 serves as a planar emitter, which is excited to resonate by the electromagnetic field coupled out through the coupling opening 14.
- the planar coupling device 16 is preferably aligned parallel to the coupling opening 14.
- the side edges of the planar radiator 16 provided here in a rectangular manner are preferably aligned parallel to the edges of the coupling opening 14, ie in the X and Y directions.
- the microstrip line 10 has an impedance transformer 17 in the area of the coupling slot 14 and in front of the abrupt end 10 'of the strip line, which transformer 17 is used for impedance matching if necessary.
- the through-contacting device 15 widens in order to be brought together again longitudinally adjacent to the end section 10 ′ of the strip line 10. hen and thus represents a closed shielding device.
- a through-contacting device 15 or also completely closed shielding walls around the strip line 10 are suitable for shielding such triplate lines and consequently for avoiding waveguide modes capable of propagation or resonance.
- the through-contacting device 15 in the form of individual through-contacts 15, 15 '(vias) which, on the radio frequency side, represent almost a continuous electrically conductive wall due to a sufficiently small lateral distance between the vias.
- the maximum shielding effect is determined by the correct dimensioning of the distance and diameter of the individual via elements 15 '.
- the distance between the walls i.e. For example, the distance between the via device 10 lying on one side of the strip line 10 and the distance between the via device 15 lying on the other side of the strip line in the Y direction does not exceed a certain value.
- the first propagable waveguide mode of a rectangular waveguide which is approximately present here, is the TEio mode, a mode with a transverse electrical (TE) field viewed in cross section.
- a corresponds to the distance between the plated-through devices 15 or via walls and ⁇ r to the dielectric permittivity of the substrate material.
- the distance a is to be reduced depending on the electrical effect of the shape of the vias or their distances and the additional (comparatively small) influence of the signal line 10.
- this wall 15 would intersect in the area of the coupling opening 14 with this orthogonally oriented coupling opening 14, so that the functioning of the coupling slot 14 and thus the antenna or transmission device does not would be more assured. It is therefore necessary to significantly increase the distance between the via walls in the vicinity of the coupling slot 14, in order to be able to reduce it to the original value only behind the slot 14 in the area of the idle signal line 10 ', for example. A merging of the via walls 15 would then also be possible behind the idling end 10 ′ of the microstrip line 10, but this is not absolutely necessary since there is no excitation due to the small distance between the via walls present there of substrate or waveguide modes would be possible. On the other hand, in order to achieve a maximum shielding effect and also to prevent electromagnetic coupling into the arrangement from the outside, the via device 15, ie the walls, is preferably brought together longitudinally adjacent to the idle signal line 10 '.
- the cutoff frequency f g of the waveguide mode drops, generally below that Usage frequency f of the antenna itself, so that the impairment of the function of the coupling opening 14 by the via walls 15 is minimal or can be taken into account in a draft of the arrangement.
- this entails the risk that cavity resonances can form within these screen walls 15 with the greatly increased distance B in the area of the coupling opening 14, which resonances greatly impair the function of the antenna if these undesirable resonance frequencies which may occur are in the useful frequency range.
- the length L of the via walls 15 in the X direction in the region of the coupling opening is to be chosen accordingly with the increased distance B of the screen walls 15 in the Y direction.
- C 0 represents the vacuum speed of light and ⁇ r the dielectric permittivity of the non-conductive filler.
- the integer index p must be greater than zero for TE modes. This results in the first excitable cavity resonance according to the TE ⁇ 0 mode
- the dimensions of the shielding device or the through-contacting device 15 must be taken into account, that the use of discrete via elements 15 'with a certain lateral spacing from one another instead of closed metallic walls influences the cutoff frequency of the waveguide modes.
- the resonator in the area of the coupling slot does not have all-round closed walls, as in the theoretical model, but rather large-area coupling and decoupling, for example in the area of the widening of the via walls 15, which influence the resonance frequency accordingly ,
- the coupling slot 14 itself also has an influence on the resonance frequency, just as the signal line 10, 10 'which runs idle below the coupling opening 14 itself can change the resonance frequency.
