Definitions
- the present invention relates to a mobile device with a Multi-band antenna having a meander-shaped conductor structure and a Contact spring for contacting the conductor structure with a transmitter / receiver electronics having.
- Such a mobile device for example, as a mobile phone or so-called mobile phone be realized.
- the dimensions for the antenna of such a device, which antenna today in the Housing is widely integrated, are for design reasons limited.
- this mobile device is increasing not just in a single network, just one Frequency range, but also in multiple networks, accordingly several frequency ranges can be operated. It will Therefore, an (integrated) antenna needed in two or more more frequency ranges is usable.
- the mobile device in question that its performance and realized its design as inexpensively as possible can be.
- the housing integrated multi-band antenna known mobile devices is realized for example from several subantenn. These subantennas are either cylindrically symmetric Helix wireforms or planar antennas that are preferred are realized on circuit boards. Because their basic forms, however do not match the shape of the case, typically generally elliptical cross-section, require such antennas in the housing relatively much space. For this reason, the Requirement for the design of the mobile device with small dimensions not or only inadequately met.
- the multi-band antenna of the speech standing mobile device by applying meandering structures to realize on flexible printed circuit board material.
- Such Multi-band antenna thus has great flexibility.
- the costs for the flexible base material and the necessary contact However, the flexible conductor material cause the costs for this antenna, several times the cost of the above non-flexible antenna corresponds.
- EP 0954054 A1 discloses a mobile radio device with a multi-band antenna, according to the preamble of claims 1 and 2.
- An object of the present invention is a mobile device of the type mentioned above, the multi-band antenna is inexpensive to produce and freedom in the Choice of the design of the mobile device guaranteed.
- the meander-shaped conductor structure and the contact spring of the antenna according to the invention as non-overlapping each other in settlement one-piece part are formed, this antenna can easily and cost-effectively manufactured by a single punching process are possibly followed by only one bending operation. Since the one-piece stamped bent part according to the invention in wide limits can be arbitrarily shaped, it can be easily adapted to the desired design of the mobile device, without taking into account the structure of the antenna got to.
- Another advantage of the antenna according to the invention is that they are with high production speed and therefore with low Manufacturing costs can be produced because of the Standard stamping and bending technology can be used.
- the multi-band antenna formed as a one-piece stamped and bent part is, there is no need for separate production and provision the antenna spring.
- the at least two meander structures are as one-piece stamped and bent part formed multi-band antenna in parallel placed next to each other so close that a clear Coupling is achieved, so that the total volume of the multi-band antenna is minimal.
- the distributed partial inductances and capacities the meander is optimally used, so that the antenna be reliably operated in several frequency bands can.
- the multi-band antenna near its first resonant frequency for one of Target frequency bands, such as GSM, use while they works so broadband near its second resonant frequency, that is a use in two other frequency bands, for example PCN and PCS is possible.
- Another advantage of integrally formed as a stamped and bent part Multi-band antenna is that a nominal impedance of 50 ohms is easily realizable, so this antenna without additional Matching network, which is required in the prior art, can be operated. This ensures that the invention formed antenna can be operated without the losses the inevitable in the prior art by adjustment elements are.
- a multi-band antenna is generally indicated by the reference numeral 10 denotes.
- the multi-band antenna 10 is a one-piece stamped and bent part, comprising a meander-shaped conductor structure with a first meander 11 and a second meander 12 and a contact spring 13.
- the two meanders 11, 12 and the Contact spring 13 are arranged relative to each other so that they do not overlap in transaction (in unwound form).
- the first meander 11 is just like the second meander 12 in settlement formed planar and these two meanders are unwound in two laterally offset planes and are connected by a connecting bridge 14 connected, which is transverse to the meandering planes runs.
- the contact spring 13 is in the region of the connecting web 14 arranged and represents an extension of this Footbridge dar.
- the first meander 11 comprises, starting from the connecting web 14 a first meander part 15 with two mutually parallel Arms 16 and 17. At the first meander part 15 closes a second meander portion 18, the two parallel to each other as well parallel to the arms 16, 17 of the first meander part 15 Arms 19 and 20 includes.
- the second meander part 18 is over a Crosspiece 21 connected to the first meander 17.
- To the second meander part joins connected via a crossbar 22, a third meander part 23, the two to each other and to the aforementioned arms 16, 17 and 19, 20 parallel arms 24, 25th includes.
- a fourth closes Meander portion 26 which, with the preceding meander portion 23rd is connected via a transverse web 27 and comprises two webs 28 and 29, the one to another as well as to the previously mentioned poor run parallel.
- a crossbar 30 closes at the fourth meander part 26 a fifth meander part 31, the like the preceding meander parts two arms 32 and 33 in includes parallel alignment.
- the fifth meander part 31 is running in a meandering direction and 90 ° inwards curved end web 34 off.
- the respective mutual distance of the five meander parts 15, 18, 23, 26 and 31 is chosen as different as the relative distance their arms 16, 17, 19, 20, 24, 25, 28, 29 and 32, 33. These distances and their sequence are in favor of by the antenna optimized frequency range to be covered.
- the second meander 12 is less complex than the first one Meander 11 and includes a single meander portion 35, the distance to lie over the end web 34 of the first meander part 11 comes and to each other as well as to the arms of the first meander 11 parallel arms 36, 37 has.
- the meander part 35 is through its lower arm 36 via another, long connecting web 38 with the contact spring 13 and the connecting web fourteenth connected.
- the relevant Reflection factor of the multi-band antenna 10 is shown in FIG. 3 shown by a solid line and generally by the reference numeral 38 denotes. Dashed lines and with the reference numbers 39,40 and 41 are the three frequency ranges or bands of the multi-band antenna 10 according to the EGSM band, the PCN band and the PCS band.
- Fig. 2 is an alternative embodiment of the multi-band antenna 10 of FIG. 1.
- the multi-band antenna shown in Fig. 2 10 ' has substantially the same basic structure as the multi-band antenna 10 of Fig. 1, but with the difference that the Meander in unwinding not in layers, but on curved ones Surfaces come to rest and with the difference that the first Meander 11 'does not include five, but only three meander parts.
- the second meander 12 ' is corresponding to the first Meander 11 configured.
- Same elements of the antenna 10 ' are denoted by the same reference numerals as in the antenna 10, which is why a more detailed explanation of these elements is unnecessary.
- Another difference of the antenna 10 'relative to the antenna 10 is that the distances of their meander parts as well as the distances the arms of the meander parts are different, so that for the antenna 10 'results in a different reflection factor than for the antenna 10.
- the invention is not limited to the two specific ones explained above Embodiments of a multi-band antenna limited. Rather, the invention can be embodied in any meandering structures be, including zigzag structures, as long as these structures in settlement as non-overlapping one-piece Stamped bent part can be realized.
