Definitions
- the invention relates to a multiband antenna arrangement for mobile devices with a planar patch antenna, which has at least two resonances, and has a ground connection and a high-frequency connection, and at least two peripheral to the planar patch antenna arranged parasitic radiators, each free from a high-frequency connection are executed.
- GSM Global System for Mobile Communication
- UMTS Universal Mobile Telecommunications System
- antennas are required, which should cover several frequency bands.
- the mobile devices are designed to be more compact and smaller in terms of their dimensions and manufactured at a lower cost.
- the antennas for mobile devices must also be optimized with regard to frequency coverage, production costs and the required antenna installation space.
- Applicant's European patent EP 1 024 552 A2 discloses a multi-band antenna which has already been improved in terms of manufacturing costs and space requirements. This improvement has been achieved by combining the multi-band antenna with several different types of antennas, all fed at one point. As a result, both the manufacturing costs and the space required by the antenna can be reduced.
- the inventors propose a multiband antenna arrangement for mobile radio devices, having a planar patch antenna which has at least two resonances and has a ground connection and a high-frequency connection, and at least two parasitic peripherals arranged at the edge of the planar patch antenna. tary radiators, each of which is free of high-frequency connection.
- the parasitic radiators can be arranged closely adjacent to the planar patch antenna. As a result, the overall space of the multi-band antenna arrangement can be made extremely compact. Under parasitic emitters antenna types are to be understood that have no high-frequency connection.
- the two parasitic radiators can be designed, for example, for the GSM850 band and for the GSM1900 band.
- the planar patch antenna can be embodied both as a planar inverted F antenna (PIFA antenna) and as a planar inverted L antenna.
- PIFA antenna planar inverted F antenna
- this planar patch antenna may have resonances in the GSM900 band and GSM1800 band.
- planar patch antenna and the parasitic radiator arranged at the edge opens up several different production methods for this multiband antenna arrangement.
- the antenna can be made of Fr4 material.
- the downside is that the antenna has to be flat for it, so it can only be extended two-dimensionally.
- Another production method for this multi-band antenna arrangement is the stamping and bending technique.
- the multiband antenna arrangement can be adapted to the shape of the mobile device housing, for example.
- MID Molded Interconnect Devices
- the stamping and bending technique three-dimensional multi-band antenna shapes can be produced.
- the MID method allows the production of finer antenna structures compared to the punch bending technique.
- the new multiband antenna arrangement also allows various types of coupling between the planar patch antenna and the parasitic radiators to be realized. Due to the nature and strength of the coupling, either the bandwidth of a resonance already generated by the antenna patch can be increased or an additional resonance can be added. In this case, the parasitic radiators can be excited by radiation coupling and / or galvanic coupling with the common ground of the antenna system of the patch structure.
- At least one parasitic radiator has a ground connection. This results in a galvanic coupling of this parasitic radiator with the planar patch antenna.
- the second parasitic radiator can then be connected to the planar patch antenna, for example via radiation coupling, that is to say the coupling between the planar patch antenna and the second parasitic radiator takes place by radiation excitations, for example via the air path.
- planar patch antenna and the parasitic radiators can be arranged in one plane.
- the multiband antenna for example, be incorporated particularly flat in the housing of the mobile device, whereby the mobile wireless device, such as a cell phone, overall narrower and thus can be made more compact.
- At least one parasitic radiator has a spatial extent, preferably perpendicularly out of the plane of the planar patch antenna.
- the antenna surface can be reduced to better meet certain design specifications.
- FIG. 1 Planar multiband antenna arrangement with a planar patch antenna, two parasitic radiators and with a total of four contact points
- FIG. 2 Planar multi-band antenna arrangement with a planar patch antenna, two parasitic radiators both using the same ground connection
- Figure 3 multi-band antenna arrangement with a planar
- FIG. 4 Multiband antenna arrangement from FIG. 3, wherein the three-dimensionally extended radiator has no mass connection.
- FIG. 1 shows a planar multiband antenna arrangement.
- the designated planar patch antenna 1 has in this Execute two resonances 1.1 and 1.2, which are symbolized by arrows.
- This planar patch antenna 1 has both a ground connection IM and a high-frequency connection I.RF.
- the parasitic radiators 2.1 and 2.2 are arranged in the same plane of the planar patch antenna 1.
- the parasitic radiators 2.1 and 2.2 each have their own ground connection 2. l.M and 2.2.M and thus have a galvanic and electromagnetic coupling with the planar patch antenna 1.
- the first parasitic radiator 2.1 extends almost over three adjacent sides of the planar patch antenna 1, while the second parasitic radiator 2.2 extends only on one side.
- two further resonances can be set. The resonances of the parasitic radiators are not shown in FIG.
- FIG. 2 shows a further embodiment of the multiband antenna arrangement.
- the planar patch antenna 1 is analogous as shown in FIG.
- both parasitic radiators 2.1 and 2.2 use the same ground connection 2.12.M and are thus galvanically and electromagnetically coupled to the planar patch antenna 1.
- FIG. 3 shows a particular embodiment of the multiband antenna arrangement.
- the planar patch antenna 1 has both a ground connection IM and a high-frequency connection IMR.
- a parasitic radiator 2.2 is arranged on the right in FIG. This parasitic radiator 2.2 extends is on one side of the planar patch antenna 1 and has by its ground connection 2.2.M a galvanic and e- lektromagnetician coupling to the planar patch antenna 1 on.
- the first parasitic radiator 2.1 arranged on the left side in FIG. 3 has its own ground connection 2.
- IM This parasitic radiator 2.1 is three-dimensionally extended and extends outside the plane of the planar patch antenna in the form of alternating meandering turns.
- FIG. 4 shows the multiband antenna arrangement from FIG. 3.
- this embodiment of the multiband antenna arrangement has only three contact points.
- the three-dimensionally extended parasitic radiator 2.1 'does not have its own ground connection and thus has a pure radiation coupling to the planar patch antenna.
- a multi-band antenna arrangement for mobile devices is provided by the invention, which can be produced particularly cost-effectively and can cover as many frequency bands with minimal space requirements in the mobile device.
