Definitions
- Antenna structure for broadband transmission of electrical signals is antenna structure for broadband transmission of electrical signals
- the present invention relates to an antenna structure for broadband transmission of electrical signals, which has a strip conductor and a capacitive or inductive coupling with the strip conductor probe, wherein the strip conductor and the probe are arranged within a predetermined distance range between the probe and strip conductor in the longitudinal direction of the strip conductor relative to each other in that electrical signals can be transmitted without contact between the strip conductor and the probe, the strip conductor comprising at least one strip electrode facing the probe electrode and a reference electrode and a dielectric carrier material located between the strip electrode and the reference electrode.
- stripline refers to all forms of conductor structures whose longitudinal extent is greater than their extension perpendicular to the longitudinal axis and which are suitable for conducting electrical signals.
- the signals are coupled out in the near field of the stripline, the signal extraction in the stripline Ideally, this should only take place in the area of the second unit Further signal transmission is undesirable, since the broadband signals can lead to disturbances in other devices or parts of the device.
- the strip conductors used for transmission are usually based on double-sided printed circuit boards.
- a dielectric support material is usually a glass fiber reinforced plastic. This support is usually on one side with a continuous conductor surface as reference electrode and on the other side with a strip electrode.
- EP 1 476 956 describes conductor arrangements which use at least one dielectric with hollow structures, the hollow structures being filled with air or a technical gas.
- the disadvantage here in addition to the high cost of generating and filling the hollow structures and the associated high costs, especially the fluctuations occurring in the homogeneity, since the cavity partitions and the air or technical gases do not have the same dielectric constant. It is therefore the object of the present invention to provide a broadband and cost-effective device for signal transmission, which has a conductor structure which achieves high signal symmetry and low attenuation values even at high frequencies.
- the present object is achieved by an antenna structure with the features mentioned, wherein the dielectric support material comprises a macromolecules containing homogeneous plastic layer, which is characterized by an alignment of the macromolecules along a preferred direction.
- the dielectric support material For the signal transmission at high data rates with low electromagnetic radiation and high immunity to electromagnetic radiation, it is necessary that the dielectric support material has a very high homogeneity.
- the homogeneity of the dielectric support material can be improved by aligning the macromolecules in a preferred direction.
- the alignment of the macromolecules leads to an unequal charge distribution in the material and an unwanted shift in the energy levels of the chemical binding energies, which are due to an interaction between the molecules Macromolecules is less likely.
- the electric and magnetic fields in the material are more homogeneous overall.
- the medullary molecules contained in the plastic layer are aligned along the longitudinal direction of the strip conductor.
- the alignment of the macromolecules in the dielectric support material can be achieved by a stretching process in which the dielectric support material is stretched by applying a tensile stress in the desired preferred direction.
- the subordinate polymers and the partially crystalline regions of the plastic layer are oriented approximately parallel to the pulling direction.
- the stretching process can increase the mechanical strength of the dielectric carrier material in the pulling direction.
- the orientation of the macromolecules along the longitudinal direction of the strip conductor can be used to observe an improvement in the mechanical strength and thus a reduced risk of breakage of the strip conductor.
- such antenna structures are particularly suitable for broadband transmission of electrical signals in which strip conductors and / or probes circulate on a circular path, as is the case for example in rotary transmission systems for computer tomographs.
- the orientation of the macromolecules along a preferred direction is sufficient if a predominant number of the existing macromolecules are aligned along the selected preferred direction.
- the transmission of the signals on both sides so the strip conductor can be operated as a transmitter and the probe as a receiver or even the strip conductor as a receiver and the probe as a transmitter.
- a bidirectional signal transmission is conceivable. Accordingly, in the sense of the present invention, the probe can also be designed as a strip conductor or as a short section thereof.
- the stripline is usually open to one side to the free space. From this side the coupling of the probe takes place.
- the probe and optionally also its sheath are closed off by symmetrical surfaces with a conductive surface. On the one hand, this makes it possible to achieve a defined impedance of the conductor system and, on the other hand, to realize a defined symmetrical limitation. If no defined reference surface were present, then at least a part of the device in which the antenna structure is mounted, would be effective as electrical reference, whereby the required symmetry would not be achieved.
- the dielectric carrier material has at least one further homogeneous dielectric layer.
- the dielectric support material in its entirety is suitable for generating homogeneous fields.
- the mechanical properties of the further dielectric layer and the plastic layer may differ, so that the dielectric support material in its entirety can also be designed according to mechanical considerations.
- the changes in the perivivance number s r of the dielectric carrier material and / or the changes in the permittivity z r of the further dielectric layer in any spatial direction are less than 5%, preferably less than 1% and particularly preferably less than 0 , 1 are. If the changes in the permittivity factor s r are smaller than the abovementioned limit values, the respective dielectric layer is particularly homogeneous, so that the dielectric losses undergo only extremely small fluctuations.
- the dielectric carrier material has at least one mechanical reinforcing layer.
- a glass-fiber-reinforced plastic layer can be incorporated into or bonded to the dielectric carrier material.
- a strip conductor with a dielectric carrier material, which has a mechanical reinforcing layer is particularly readily mechanically moldable or reworkable, so that the strip conductor can be adapted particularly well for receiving in an electrical device.
- the carrier material has at least one equipotential surface. Equipotential surfaces help to balance asymmetries in the dielectric carrier material, so that the generated electrical and / or magnetic field is largely symmetrical.
- layers of conductive material in particular material with a high conductivity, can be embedded in the dielectric carrier material.
- a layer of conductive material with an incomplete surface coverage such as e.g. a metal grid, are introduced directly into the plastic layer during the production of the dielectric support material, which filters out in operation as Equitotential Structure asymmetries or disturbances of the electrical and / or magnetic fields generated.
- these layers can be introduced in an electrically insulated manner or can also be terminated without reflection at the ends of the strip conductor.
- the strip conductor has a mirror-symmetrical construction in cross-section, the extent of the electric and magnetic fields produced can be particularly well limited.
- the symmetry with respect to the longitudinal center plane of the strip conductor is to be understood.
- the configuration of symmetrical strip conductors prevents inhomogeneities and / or asymmetries from being formed by different propagation times in the strip electrode, the reference electrode and / or the dielectric carrier material.
- the smallest distance between the strip conductor and the probe, measured from the surface of the strip electrode facing the probe to the surface of the probe facing the strip conductor is less than 15 mm, preferably less than 8 mm, and is particularly preferably in the range from 1 mm to 4 mm.
- the at least one strip electrode and the reference electrode are each printed on a plastic film. It has been found that the production of a strip conductor can be realized in a particularly cost-effective manner if the strip electrode and the reference electrode are each printed on a plastic film, and these are subsequently arranged on or on the dielectric carrier material. Particularly preferably, the strip electrode and the reference electrode is made of copper, which is printed on a respective plastic film.
- the plastic film itself can be the dielectric carrier material in one embodiment.
- the strip conductor has two strip electrodes, which are arranged in the same plane parallel and at a distance from each other.
- Such symmetrical strip conductors can be realized particularly low radiation, which in particular can be compensated for interference by using symmetrical or asymmetrical, electrical signals on two parallel stripes.
- parallel should also encompass such arrangements in which the strip electrodes are indeed structured in themselves but, as a whole, run substantially parallel to one another.
- a transmission electronics is provided, which is designed so that it applies signals between the first strip electrode and the reference electrode and between the second strip electrode and the reference electrode, which have an opposite polarity.
- signals between the first strip electrode and the reference electrode and between the second strip electrode and the reference electrode, which have an opposite polarity.
- a differential transmission is made possible in which selective disturbances, in particular asymmetries and inhomogeneities, can be compensated.
- Such symmetrical antenna structures are also particularly low in radiation because the electric and magnetic fields in the far range cancel each other out.
- the antenna structure 1 shows a partially broken away perspective view of an antenna structure 1 according to the invention.
- the antenna structure 1 has a strip conductor 2 and a probe 3 which are arranged to be movable relative to each other within a predetermined distance range in the longitudinal direction of the strip conductor 2.

- a voltage signal provided by a transmission electronics 1 1 is applied between the strip electrodes 4, 4 'and the reference electrode 5, electrical and magnetic fields are generated by charge displacements in the dielectric carrier material 6. Due to the arrangement of the strip electrodes 4, 4 ', the reference electrode 5 and the dielectric carrier material 6, the field lines of the generated fields extend substantially perpendicular to the longitudinal direction of the stripline 2. In order to reduce the influence of extraneous fields, asymmetries and / or inhomogeneities, However, the voltage signals between the first strip electrode 4 and the reference electrode 5 and between the second strip electrode 4 'and the reference electrode 5 opposite polarities otherwise an identical waveform.
- the dielectric carrier material 6 comprises a plastic layer containing macromolecules, wherein the vast majority of the macromolecules contained in the plastic layer are aligned in the longitudinal direction of the strip conductor 2.
- the orientation of the macromolecules leads to the fact that the dielectric carrier material 6, which here is manufactured solely from the plastic layer 7, has the required homogeneity to allow broadband transmission of electrical signals with spatially limited electrical or magnetic fields.
- the generated fields can be transmitted to the probe 3 by means of capacitive or inductive coupling, the strip conductor 2 and the probe 3 having a minimal distance from one another, measured from the surface of the strip electrode 4 facing the probe to the strip conductor 2 Surface of the probe 3, smaller than 15 mm.
