Definitions
- the invention relates to an antenna for radio-operated Communication terminals.
- the development goes to ever smaller devices, which should be able to work in multiple frequency bands to work optionally.
- the market always demands smaller and cheaper mobile devices.
- the devices must be equipped with antennas, which meet these requirements, which means that they take up little space have, for a function in several frequency bands or a broadband frequency range and are inexpensive to manufacture.
- the required minimum total electrical length of the Antenna - a quarter of a wavelength or a multiple of which with the intended frequency bands - with the previous ones known structures at the given volume no longer can be realized.
- EP 0997 974 A1 Examples of the prior art are EP 0997 974 A1 and called EP 102 774 A2.
- a planar antenna is described in EP 0997 974 A1, the antenna body slotted in such a way in a certain way is that the top of the slot has a direction which are more than 90 ° from the direction of the other end of the Slot deviates.
- This slot in the sense of invention described there can be carried out.
- the other The effective antenna length increases with the The teaching of this document also sets limits.
- EP 102 677 A2 there is one planar inverted-F antenna described in its overall dimensions the size determining the antenna for a given Emission frequency is designed, and that in the longitudinal direction has one or more indentations or gradations, by means of which one or more geometric Routes result from several straight or curved Put together individual sections, and those from the feed point or another corner or end point to one of the endpoints created by the indentations or gradations run, and over the course of which there is an emittable Wave with a higher frequency than the given lower one Frequency.
- the present invention is based on the object also for radio-operated communication terminals increasingly smaller dimensions an antenna with larger effective electrical length to create the largest possible Frequency ranges suitable and inexpensive to manufacture.
- the one according to the invention is particularly advantageous Antenna, because at given volumes through the novel Detour lines the area between the patch area and better use of the ground area and thus the broadband the antenna is raised.
- the new detour lines also enable a reduced space requirement of the patch antennas. Further advantageous configurations of the antenna result from the dependent claims and from the following description of exemplary embodiments with reference to the drawings.
- FIG. 1 schematically shows a patch antenna 1 with an antenna body 1 a, which is shown above a printed circuit board 2 is arranged, which forms a ground plane.
- a feed contact 3 For electrical Connection between the antenna body 1a and circuit board 2 serve a feed contact 3 and a ground contact 4.
- detour lines 9 and 10 Extend in the outer regions 5 and 6 of the antenna body 1a along its edges 7 and 8 detour lines 9 and 10, which resulted from multiple flanges of the edges 7 and 8 are. These detour lines 9 and 10 are caused by Flanging or folding the edges 7 and 8 once from the outside areas 5 and 6 facing inwards and another sometimes directed outwards.
- FIG. 2 shows a variant of a patch antenna 11, in which the detour lines 12 and 13 are not exclusive lie in the outer areas of the patch antenna 11, but additional detour lines 13 within the antenna body 11a are arranged. Electrical connections will be analogous to the embodiment according to FIG. 1 by at least a feed contact 14 and a ground contact 15 are made.
- a printed circuit board 16 assigned to the patch antenna 11 lies opposite the patch antenna 11 and points in each case between the detour lines 12 and 13 shield covers 17 and 18 on.
- the shield covers 17 and 18 belong to shield chambers, such as for example one - provided with the reference number 25 - in Figure 3 is shown schematically. In shield chambers 25 are components not shown here, which are electromagnetic must be shielded.
- These umbrella chambers 25 can be closed at the top open to be able to access the components. To they can be provided with screen covers 17 and 18, by which can open the screen chambers 25, and with which the shielding chambers 25 can be closed again in a radiation-tight manner are.
- the arrangement and design of umbrella chambers is not decisive and is at the discretion of the expert.
- the patch antenna 19 shown there has an antenna body 19a, in which the outer regions 20 and 21 in several Directions are folded several times. Through additional slots S3 in several directions becomes the slotted and folded Antenna body 19a optimally the required radiation conditions customized.
- an umbrella chamber 25 is advantageously arranged again.
- the embodiment shown in Figure 4 shows one Patch antenna 26, in which the antenna body 26a on its Outer areas 27 and 28 are folded several times such that its folds in several levels within the area lie between antenna body 26a and a ground surface 29, these outer regions 27 and 28 via the ground surface 29 protrude, which is embodied here by a circuit board 29 becomes.
- too electrical radiation properties of the patch antenna 26 still optimize if, for example, the detour lines in several Directions are realized, and / or the antenna body 26a slotted in at least one direction in a manner becomes, as is the case with the previously described exemplary embodiments has already been shown.
- An expansion of the patch area over the edges of the ground plane 29 also allows for reduced size Ground areas or enlarged for given ground areas Patch surfaces.
- FIG. 5 shows a further variant of an inventive one Patch antenna 30 shown.
- An antenna body 30a is spatial structured wavy.
- the wavy spatial Structure of the antenna body 30a can be the required adjust electrical properties by wavy spatial structure uniform or partially non-uniform is trained.
- the waveform can be both harmonious as well as being inharmonic, of course also Mixed forms are feasible. Even spatially from the waveform different surface structures, such as spatial meanders with uniform but also non-uniform Meandering is conceivable.
- this embodiment is not shown how an electrical connection between the antenna body 30a and an assigned ground plane 31 is produced, but this is based on the above Embodiments easily for the expert understandable and requires no special explanation.
- the ground area 2, 16, 22, 29, 31 can be of any shape, and not necessarily to the Adapted shape of the antenna body 1a, 11a, 19a, 26a, 30a have to be.
- the individual areas of the antenna body 1a, 11a, 19a, 26a, 30a and the ground surface 2, 16, 22, 29, 31 can have different heights in several directions, caused by folding, flanging, cranking and / or Waveform so that at least the covered area between the antenna body 1a, 11a, 19a, 26a, 30a and the ground plane 2, 16, 22, 29, 31 spatially used in several levels becomes.
