Definitions
- Multi-resonant antenna unit associated printed circuit board and radio communication device
- stub antennas that protrude beyond the housing, i. are arranged outside the housing.
- Such outwardly projecting stub antennas can render the respective radio communication device unwieldy, bend or even break off if the mechanical loads are too high. Furthermore, they affect the visual appearance for some desired geometry or for some design of the housing of the radio communication device.
- patch antennas i. Flat antennas used. These typically have at least two power feeds across which are spatially separated, i. separate patch zones are excited electromagnetically, which are assigned to at least two different frequency ranges. Under certain circumstances, such patch antennas may require too much space in the respective radio communication device. In addition, their power supply via their at least two separate contacts can be too expensive. In addition, unwanted electromagnetic coupling effects between their two power supply contacts are possible.
- the invention has for its object to provide a multi-resonant antenna unit for transmitting and / or receiving radio radiation fields in at least two frequency ranges with further reduced dimensions, which can be fed in a simple manner with electric current. This problem is solved by the following multi-resonant antenna unit:
- the second antenna structure is an integral part within the overall course of the first antenna structure.
- the second antenna structure forms only a partial length of the overall course of the first antenna structure.

- FIGS. 4 to 6 three further embodiments of a multi-resonant antenna unit according to the invention.
- FIG. 1 shows, in a schematic and enlarged representation, an antenna structure AT1 used in radio communication devices by way of example with two separate antenna branches or antenna branches AA1, AA2 for two different frequency bands.
- Each Antenennzweig AAl or AA2 is formed by an electrically conductive, strip-shaped conductor track and / or an electrically conductive wire.
- the first antenna branch AAl and the second antenna branch AA2 have a common base FP, ie their input-side end faces are connected to each other via a common electrical contact line CLl with electric current ECL of a power supply SPl to feed.
- This current feeding area SP1 can be formed both flat and punctiform.
- the current supply region SP1 is shown in a punctiform manner by way of example. It represents the point of supply for the electric current EC1 and is therefore representative of a power source.
- the two antenna branches AAl, AA2 extend spatially separated from each other in different spatial directions. In other words, the two antenna branches AA1, AA2 are free in mutually different space regions or - zones.
- the runlength LIl of the first antenna branch AAl is selected to be smaller than the runlength L12 of the second antenna branch AA2.
- the run length L12 of the longer antenna branch AA2 is substantially preferably ⁇ / 4, i. a quarter of the resonance wavelength of the lower frequency range, or multiples of ⁇ / 4 for the formation of standing electromagnetic waves and concomitantly selected for decoupling and / or coupling electromagnetic radio waves.
- the run length LIl of the shorter antenna branch AAl substantially corresponds to ⁇ / 4 of
- Resonant wavelength ⁇ of the higher frequency range or multiples of ⁇ / 4 of the higher frequency range Resonant wavelength ⁇ of the higher frequency range or multiples of ⁇ / 4 of the higher frequency range.
- the longer antenna branch AA2 in the first approximation in the form of an open loop or loop as a geometry.
- the longer antenna branch AA2 in the first approximation has the shape of the lower case letter 1 in its upper portion.
- the shorter antenna branch AAl has a semicircular or semi-oval geometry shape.
- the two antenna branches AAl, AA2 of the known antenna structure ATl act as two separate stub antennas.
- Such an antenna structure with two separate antenna branches may in practice require too much space under some circumstances. This is especially true when the antenna structure is to be housed inside the housing of a radio communication device, which already has a multiplicity of other electrical components there.
- FIG. 2 schematically shows, in an enlarged illustration, a first multi-resonant antenna unit AT2 with an antenna structure which is made more compact than the antenna structure AT1 of FIG.
- This multi-resonant antenna unit AT2 has only a single current feeding area SP1. This may be flat or punctiform. It is powered by an electrical power source, which has been omitted in the figure 2 for the sake of clarity. Starting from this single, i. only one
- This patch element PAl ie electrically conductive surface element.
- This patch element PAl is only a single antenna branch AZl, which is formed spirally.
- This spiral-type antenna branch AZ1 is composed of subsections SEI1, SE12, SE13, SE14 and SE15 arranged at right angles to one another. In this case, the sections SEI1 to SE15 are formed by strip-shaped conductor tracks and / or electrically conductive wires.
- the input-side subsection SEI1 of the spiral-like antenna branch AZ1 extends, starting from the upper edge of the rectangular patch element PA1, along its imaginary rectilinear extension. Relative to this offset by 90 °, the second subsection SE12 closes thereon at. Opposite its rectilinear course of the third, rectilinear section SE13 is offset by 90 °.
- the subsequent, fourth subsection SE14 and the fifth subsection SE15 In this case, this end-side section SE15 is free in the room. It runs essentially parallel to the first section SEIl.
- the fourth and the second subsection SE12, SE14 likewise run essentially parallel to one another.

- the individual antenna branch it is also possible to choose a different geometry for the individual antenna branch. So it can be e.g. be expedient to provide for the individual antenna branch an elliptical or circular, spiraling inward spiral shape. Alternatively, it may be expedient to provide an outwardly spiraling spiral as an antenna branch, whose end portion protrudes freely.
- the first antenna unit AT2 i. in detail, the point-like current feeding area SP1, the contact line CL1, the patch element PA1 as well as the subsections SE1 to SE14 of the antenna branch AZ1 essentially in the same positional plane, so that a plane-planar antenna structure is formed in the first approximation.
- the overall course of the spiral antenna branch AZ1 has an overall length L22. This overall course of the spiral antenna branch AZ1 forms a first resonant antenna structure for a first frequency range.
- the freely projecting, end-side end section SE15 of this spiral-type antenna branch AZ1 acts as a second resonant antenna structure for a second Frequency range. Since the end-side end portion SE15 constitutes only a partial length L21 of the total length L22 of the entire spiral-type antenna branch AZ1, the end-side portion SE15 is assigned a higher frequency range than the overall profile of the spiral-type antenna branch AZ1.
- the end-face end section SE15 For electromagnetic excitation of the end-face end section SE15, this is arranged in such a way relative to the input-side patch element PA1 that it can be inductively and / or capacitively connected thereto, i. generally printed electromagnetically coupled.
- the electromagnetic Uberkoppel Complex is indicated in the figure 2 by a dash-dotted frame and denoted by CZl.
- the partial length L21 of the end-side subsection SE15 to the total length L22 of the spiral-type antenna branch AZ1 is substantially in the same ratio as the assigned higher frequency range to the assigned low frequency range.
- the total length L22 of the spiral antenna branch AZ1 is preferably selected between 70 and 90 mm.
- the end-side section SE15 of the spiral-like antenna branch AZ1 preferably has a partial length L21 of between 10 and 25 mm.
- the partial length L21 of the front end section SE15 is preferably selected in about one quarter of the resonance wavelength of the higher frequency range, ie approximately ⁇ / 4, where ⁇ is the resonance wavelength of the higher frequency range. Expediently, multiples of ⁇ / 4 may be for the partial length L21.
- the total length L22 of the spiral antenna branch is selected to be substantially one quarter of the resonance wavelength of the lower frequency range or multiples of ⁇ / 4.
- a uniaxial helical antenna structure is provided, the overall shape of which forms a first resonant antenna structure for a lower frequency range, and whose frontally free end portion serves simultaneously as a second resonant antenna structure for a higher frequency range.
- the single, spiral-like antenna branch alone takes over the function and operation of two separate antenna branches such as AAl, AA2 of the antenna structure ATl of Figure 1.
- the multi-resonant antenna unit occupies the only single, spiral antenna branch, the overall course of a first resonant Antenna structure for a lower frequency range forms and its front end portion of a second resonant antenna structure for a higher
- Frequency range provides less space than the known antenna structure ATl of Figure 1, which has two spatially separate antenna branches AAl, AA2.
- FIG. 3 shows a schematic representation of a detail of a printed circuit board LP of a radio communication device MP, the outer housing GH is indicated by dash-dotted lines.
- the lower part of the display or the display device DP of the radio communication device MP is additionally shown with.
- the multi-resonant antenna unit AT2 of Figure 2 is coupled. It is so compact that besides it there is an input / output
- the multi-resonant antenna unit according to the invention is characterized in particular by the fact that it occupies less space within the housing GH, so that there more interior space for the plurality of further electrical components for Is available and overall the radio communication device MP can be made very compact in terms of its dimensions. In particular, further miniaturization is possible.
- Figure 4 shows in schematic and in an enlarged
- a meander-shaped track MA is additionally interposed between the spiral-type antenna branch AZ1 and the input-side patch element PA1. This makes it possible, along a relatively short rectilinear section, to extend the run length of the spiral antenna branch AZ1 by the meandering LL2 *.
- the input-side patch element PA1 has, in particular, the function of widening the bandwidth of the lower frequency range. This bandwidth broadening is particularly advantageous for the 900 MHz GSM frequency band.
- FIG. 5 shows, in a schematic and enlarged representation, a third multi-resonant antenna unit according to the invention, which is modified relative to the first antenna unit AT2 according to the invention of FIG.
- Figure 2 is the single, spiral-like
- Antenna branch AZl supplemented by an input-side section SE21.
- This input-side subsection SE21 is offset from the rectilinear course of the subsection SEI1 by 270 ° and terminates the helical antenna branch AZ1 laterally. It runs essentially parallel to the section SE12. This results in an increased overall length L32 for the modified, spiral-like antenna branch AZ1 * of the third multiple-resonant antenna unit AT4 by the partial length L22 ** relative to the antenna branch AZ1.
- a transverse web VTIl projecting inwards into the structure of the spiral antenna branch AZ1 * is provided transversely to its longitudinal extension. It is used for bandwidth broadening for the lower frequency range, the overall course of the modified spiral-like
- Antenna branch AZl * is assigned.
- the transverse web VTI1 is substantially perpendicular to the axial longitudinal extent of the input-side subsection SE21.
- the input-side subsection SE21 represents in particular the left-side frame of an imaginary rectangle, which forms the outer border of the multi-resonant antenna unit AT4.
- the partial section SE12 has a transverse strip CT3 projecting into the interior of the spiral of the antenna branch AZ1 * and extending substantially at right angles to the axial longitudinal extent of the section SE12. It serves to electromagnetically excite the inwardly projecting end section SE15 of the spiral antenna branch AZ1 *.
- FIG. 6 shows a further advantageous, multi-resonant antenna unit AT5.
- the antenna branch AZ2 is composed in detail of mutually perpendicular sections SE31 to SE38.
- the electrical connection between the current feed area SP1 and the input-side section SE31 takes place via the electrical contact line CL1.
- the input-side section SE31 has transverse to its axial longitudinal extent two transverse strips VT21, VT22, which serve the bandwidth broadening of the lower frequency range.
- the subsections SE31 to SE38 are arranged in a rough approximation such that their imaginary outer border as viewed overall has a substantially right-angled shape.
- the input-side, first section SE31 forms approximately the left broad side and the section SE37 the right broad side of this imaginary right-side.
- the sections SE32, SE36 run along the lower longitudinal edge of this imaginary right-hand corner, while the freely projecting, front-side end section SE38 of the spiral antenna branch AZ2 extends along the upper longitudinal side of this imaginary right-hand corner.
- the sections SE33, SE34, SE35 form a protuberance into the interior of the spiral of the antenna branch AZ2, ie a bulge in the straight longitudinal course of the sections SE32, SE36 into the interior of the spiral of the antenna branch AZ2.
- the subsection SE34 and the end-side end section SE38 This results in an inductive and / or capacitive coupling between the subsection SE34 and the end-side end section SE38, as a result of which it is electromagnetically excited along its partial length L41 for the higher frequency range.
- the overall course of the antenna branch AZ2 along its entire length L42 serves as a resonant antenna structure for the lower frequency range.
- Radio beams of a lower frequency range acts, with the sub-section, which is associated with the higher frequency range, in particular its end free-standing end portion such. SE15, to couple such inductively and / or capacitively that this acts as a second antenna branch for a higher frequency range.
- This second antenna branch is integrated in the total run length of the first antenna branch, i. it forms a partial length of the total length of the first antenna branch and is therefore an integral part of the first antenna branch.
