Definitions

  • the present invention relates to an antenna, in particular for use in mobile communications.
  • PCB multiband antennas are more complex to manufacture and have low reproducibility.
  • An object of the invention is to provide an antenna which is able to use multiple frequency bands at the same time cover and has little space.
  • an antenna according to the invention in particular a multiband antenna for mobile devices, with one combined antenna structure provided, at least a loop antenna structure with at least one rod antenna structure is combined.
  • Antenna structure has that in several frequency bands and / or in one or more broadband Frequency ranges can be interpreted and in any communication terminal can be integrated.
  • the correspondingly combined antenna structure can preferably be used in all its dimensions relative to the adaptation to the different requirements from device to device vary in their values.
  • the relative remain Dimensions of the combined antenna structure, i.e. the dimensions the loop antenna structure in relation to the rod antenna structure receive.
  • the rod antenna structure as a rod or as a meander or in any other form, such as in a waveform can be realized, as can the loop antenna structure in meandering, rod or other suitable Form.
  • the combined antenna structure is preferably designed such that that space optimization adapted to the respective device he follows.
  • the combined antenna structure preferably has in the Frequency band with the lowest frequency is a loop antenna structure on. So she owns at least there a ground contact.
  • the ground contact can in principle on everyone any position of the antenna structure can be attached. However, it is preferably provided at the end of the structure, i.e. the combined antenna structure preferably has at least one of its ends has a ground contact on. This makes the frequency lower.
  • the radiating element can be used for reasons of space can also be carried out in another form. Preferably this structure becomes the maximum distance from the ground contact of the second radiating element.
  • the Antenna also made of several radiating structures as one in Form of a loop antenna structure and / or a rod antenna structure consist of a multi-band antenna with more to be realized as two bands.
  • the position of the antenna on or in the respective device is irrelevant. It can depend on the respective device properties and the type of use can be adjusted.
  • the rod antenna structure is preferably located on the end face of the device. Always pay attention to the distance of the Radiator element to the ground surface.
  • Antenna has the combined antenna structure as contact elements at least one RF contact and at least a ground contact. In principle there are also several Ground contacts possible for a desired antenna behavior adjust.
  • the RF contact is preferably at the beginning of the Attached meandering, but can also be in another place be positioned.
  • Antennas are tuning elements on the combined antenna structure intended. These can be nearby, i.e. below, above or next to one or more radiant Structures.
  • the tuning elements can, for example in the form of a patch.
  • the antenna can also have a stepped or compressed structure have, i.e. the height of the antenna above the corresponding device PCB can both in terms of their length and their Vary in width.
  • the contour of the emitter element is preferably the antenna according to the invention the course of the housing adjusted to use the volume as well as possible.
  • the radiation properties are improved and increases the bandwidth by making the plane of the antenna parallel runs to the metallic surface of the device.
  • she can also be at a variable distance from the metallic EMC shielding of the radio-operated communication terminal run.
  • Antenna has the antenna structure suitable dielectric and / or magnetic materials.
  • dielectric and / or magnetic materials can affect the antenna structure fill in partially or completely. They are too Combinations of different dielectric and / or magnetic Substances or air possible.
  • a first preferred method according to the invention for Production of an antenna according to the invention becomes the antenna realized on a PCB (Printed Circiut Board).
  • an antenna according to the invention is made from a Sheet metal is manufactured using a stamping and bending technique.
  • the antenna according to the invention can be used according to the invention as run a slide.
  • the structuring can be done using different technologies, known from the selective structuring of the so-called MID applications.
  • full-surface metallization with subsequent laser structuring the application of a primer for metallization by masking or pad printing (Boymetec process) and subsequent metallization.
  • metallization is chemical deposition and / or galvanic Deposition of metals.
  • Another variant is z. B. the printing of a conductive lacquer by stamp, tampon or screen printing.
  • the material on which the structure in the case of the PCB and the MID technology is applied is freely selectable. Preferably it is suitable for high frequencies. It can also be pliable flexible Be material, which means an adaptation to housing or device contours is possible.
  • the invention further comprises the use of the invention Antenna for installation or integration into a communication terminal, especially in a mobile device.
  • the Antenna according to the invention can also in any way be connected to the communication terminal, for example be placed on the outside or fold out or it can on a conventional circuit board, for example in GSM desk phones mounted in radio or telecommunications modules become. Ultimately, it can also function as an independent external Antenna operated. In all cases, a suitable antenna dimensions are observed.
  • FIGs 1a and 1b is a side and a top view of a Part of a mobile device 1 shown, in which a antenna 2 according to the invention is integrated.
  • a PCB 3 on which a shield cover 4 rests and at one end there is an earpiece 5.
  • the integrated antenna 2 according to the invention is located in a suitable distance h2 to the screen cover 4.
  • the height of the Antenna 2 above the device PCB 3 can be within the length and / or the width vary.
  • the plane preferably runs the antenna 2 parallel to the metallic surface. Thereby the radiation properties can be improved and the bandwidth will be increased. But it can also be in a variable Distance to the metallic EMC shield 4 of the mobile device 1 run.
  • FIG. 1b shows a top view of part of a mobile radio device 1 with an integrated antenna according to the invention 2.
  • the PCB 3 and the one on it can be seen attached shield cover 4.
  • the antenna 2 has two contact elements on, namely an RF contact 6 and a ground contact 7.
  • the position of the antenna in the device is irrelevant, can therefore the device properties and the type of application be adjusted.
  • the rod antenna structure is preferably located on the front of the device.
  • Figure 2 shows the basic structure of an embodiment an antenna according to the invention 2. All dimensions can be Adaptation to the set, different from device to device Requirements vary in their values.
  • the rod 8 can also be in a meander shape, the meander 9 in Bar shape or in any other shape can be realized.
  • the tape preferably forms the lower frequency has the loop antenna structure 10 and thus ground contact 11.
  • the ground contact 11 can on everyone any position of the loop antenna structure 10 attached become. However, as shown here, it is preferably due to End of structure.
