Definitions
- the present invention relates to an antenna, in particular a helical antenna, a use of such an antenna and a method for producing such an antenna.
- the design plays, i.e. the outer
- Appearance plays a major role in the design of antennas.
- modern mobile devices should increasingly not only be in a mobile network, i.e. m in one frequency range, but can be used in several frequency ranges.
- Multiband antenna systems are currently used, which consist of several individual antennas, for example of cylindrical symmetrical helix wire structures or planar antennas (eg so-called PCB boards).
- these known solutions can be installed in a housing which does not correspond to the basic shape of the antenna, ie an antenna housing with an elliptical cross section can be selected instead of a cylindrical symmetrical cross section.
- a relatively large amount of space is then required for the entire antenna system, so that the design requirement for the smallest possible device dimensions cannot be met or the desired design cannot be realized.
- the present invention is therefore based on the object of proposing an antenna which on the one hand can be produced as simply and inexpensively as possible and on the other hand allows a great deal of latitude in the design of the antenna's external design.
- the antenna should enable simple expansion to a multiband antenna.
- the above-mentioned object is achieved by an antenna with the features of claim 1. Furthermore, a method for producing such an antenna is proposed with the features of claim 18.
- the subclaims each describe preferred and advantageous embodiments of the present invention.
- the antenna according to the invention describes a helical basic structure which can be produced particularly inexpensively by simply punching and bending a metal or sheet metal part.
- the antenna comprises convexly curved and strip-shaped antenna elements which are connected and arranged in rows m rows extending over the longitudinal direction of the antenna such that they emulate the shape of a helix.
- the basic structure of a helix is modified such that the antenna only has elements which - viewed in the longitudinal plane of the antenna - do not overlap, so that the helix structure can be produced by a simple stamping process.
- the structure of the antenna according to the invention is not necessarily cylindrically symmetrical and does not necessarily have to contain planar arrangements.
- antenna elements can be shaped as desired within wide limits, so that there is a great deal of design freedom in the design of the outer design and a structure conforming to the design, for example a non-cylindrical symmetrical cross section, can be formed much more easily.
- the standard technology of punching and bending metal or sheet metal parts required to manufacture the antenna according to the invention enables extremely high production speeds and thus low production costs.
- the antenna contact spring which establishes the electrical contact between the antenna and the electronics of the device to be operated with it, can be produced in one piece from a single stamped and bent part, which is particularly cost-effective since the antenna contact spring with the antenna base structure is maintained can be produced in the same production step.
- the above-described helical basic structure of the antenna according to the invention can easily be expanded to a dual-band, triple-band or generally multiband antenna.
- the helical base structure with the series connection of the convexly curved antenna elements only has to be supplemented by a further, parasitic antenna element in the form of an elongated web which runs parallel to the helix and is also arranged such that the individual elements of the antenna are in the longitudinal plane of the The antenna does not overlap at any point, so that this parasitic antenna element together with the helical base structure can also be produced from the same stamped and bent part.
- the parasitic and web-like antenna element is not only connected in parallel to the helical base structure, i.e. at the bottom
- the volume of the antenna is minimal.
- the distributed partial ductivities and capacities of the individual antenna elements can be exploited in such a way that the antenna, which consists of a parallel connection and a series connection of preferably elliptically curved half rings and straight webs, can be used to operate several frequency bands.
- no additional adapter circuit is required to start up the antenna.
- FIG. 1 shows a perspective view of a punchable T ⁇ pleband antenna according to a preferred exemplary embodiment of the present invention
- FIG. 2 shows the course of the reflection factor of the antenna m shown in FIG. 1 as a function of the operating frequency.
- the antenna shown in FIG. 1 has a helical basic structure.
- This helical basic structure is realized in that convexly curved antenna elements 2, 3 with mutually opposite bends or curvatures are alternately arranged in such a way that an antenna element 3 bent downwards follows an antenna element bent upwards and vice versa.
- the adjacent ends of two adjacent antenna elements 2, 3 are preferably straight and m in the longitudinal direction
- Bridges 4, 5 extending antenna or helix are connected to one another in such a way that the individual antenna elements 2, 3 are connected in series and the helix structure shown in FIG. 1 is formed.
- the helical antenna shown in FIG. 1 can easily be produced by a stamping and bending process. To do this you need to In a metal or sheet metal part, only the strip-shaped and preferably mutually parallel antenna elements 2, 3 and the adjacent ends of the webs 4, 5 connecting the antenna elements are punched and the antenna elements 2 and 3 are alternately bent as shown in FIG. 1.
- the antenna elements 2, 3 can also run obliquely to each other. From Fig. 1 it can be seen that the individual elements of this helical antenna are arranged such that - viewed in the longitudinal direction of the antenna - they do not overlap at any point, which would otherwise hinder or even make the stamping process impossible.
- the bending radii of the individual convexly curved antenna elements 2 and 3 are preferably identical, so that a uniform helical structure results. Furthermore, for design reasons, it is recommended to bend the antenna elements 2 and 3 elliptically. However, the antenna elements 2 and 3 designed as half rings can in principle be shaped as desired with certain limits in order to implement a specific design.
- an antenna contact spring 1 is preferably formed in one piece at the lower long end, which serves to connect the actual antenna to the electronics of the device to be operated with it, preferably a mobile radio device.
- the antenna contact spring 1 can also be produced simply by appropriate punching and subsequent bending of the same metal part. 1, the antenna contact spring 1 is simply formed by an elongated section, which is then bent into a desired shape. The shape of this section can be chosen as long as the length of the section does not become too long.
- a further parasitic antenna element 6 is connected in parallel to the helical basic structure described above, which is connected at the lower long end of the antenna to one end of the first antenna element 2 and the antenna contact spring 1.
- This further antenna element 2 runs in particular on the same plane as the connecting webs 4 and 5 parallel to the helical basic structure of the antenna and is also arranged in such a way that there are no overlaps.
- This further antenna element 6 can thus also be produced from the same stamped part as the rest of the antenna.
- the parallel-connected antenna element 6 is arranged so close to the helical base structure with the antenna elements 2, 3 that a clear electromagnetic coupling occurs between these antenna elements 2, 3 and 6 during operation and, on the other hand, the overall volume of the antenna can be minimized.
- an end section 7 which preferably runs parallel and laterally to the last convexly curved half ring of the helical structure.
- This bent end section 7 can have the same bend as the upwardly bent half rings or antenna elements 2 and serves to realize the necessary conductor strip length with a minimum total antenna volume with optimized electromagnetic coupling.
- the end section 7 completes the construction of the antenna in the longitudinal direction.
- the distributed partial conductivities and capacities of the antenna structure thus formed and shown in FIG. 1 can be used in such a way that the antenna is divided into several
- Frequency ranges can be operated.
- the antenna can be used near one of the first resonance frequencies for one of its target frequency bands and at the same time work so broadband near a second resonance frequency that use in two further frequency bands is possible.
- 2 shows the reflection factor
- the reflection factor at a first resonance frequency in the range of the frequency range of the GSM mobile radio standard (Global System For Mobile Communication) and also at a second resonance frequency within the overlapping frequency ranges of the mobile radio standards PCS (Personal Communication Services ) and PCN (Personal Communication Network) assumes minimum values so that the antenna can be operated in accordance with m three different frequency bands and in accordance with three different mobile radio standards.
- Antenna structure possible to realize a nominal impedance of about 50 ohms at the same time, so that the antenna can be operated without a matching network or only with a small number of matching elements.
