Definitions

  • the present invention relates to an antenna for radio-operated Communication terminals.
  • antennas are needed, which are able are to cover several frequency bands at the same time.
  • market is asking for smaller and cheaper ones Mobile devices. That is why antennas are required, some have a small footprint, easily for a function in several frequency bands or a broadband frequency range can be designed and manufactured cheaply.
  • the object of the present invention is to provide an antenna for radio-operated communication terminals to specify which simple is built up and simultaneously several frequency bands can cover.
  • An antenna for radio-operated communication terminals for Solution to the problem according to the invention is characterized by one consisting of several different antenna types Combination, where each antenna type exists one or more times can be and where the combination of several antennas is only fed in at one point.
  • the antenna according to the invention is easy and inexpensive to manufacture, requires little space and is easy for a function in several frequency bands or in one broadband frequency range can be designed.
  • FIG. 1 and 2 are the two actual antennas in FIG. from which the multiband antenna according to the invention is composed is referred to, it being in that shown in Figure 1
  • a metallic EMC shield 4 is covered with a metallic EMC shield 4 in the Multiband antenna shown, this forms metallic EMC shielding for the two antennas 1 and 2 necessary dimensions.
  • connection between the radiator element of the antenna 1 and the metallic EMC shield 4 is connected via the ground connection 5 manufactured.
  • the actual feeding point of the antenna is marked with 6.
  • With 7 is a symbolic coupling of the two antennas 1 and 2 indicated. This coupling can be capacitive, inductive, blasted or galvanic his. Due to the type of coupling, different parameters the antenna.
  • ground connection 5 is also selective, as well as several times is possible.
  • FIG. 2 now shows a perspective representation of a principle Multiband antenna according to the present invention, which from a planar inverted-F antenna 8 and a planar Inverted L antenna 9 is made.
  • the two antennas 8 and 9 via a galvanic coupling 10 coupled together.
  • Feeding the multiband antenna takes place by means of a feed point 11, which with the planar Inverted L antenna 9 is connected.
  • the ground connection of the Antenna configuration shown takes place via the ground connection 12th
  • FIG. 3 shows an antenna configuration which consists of a Microstrip antenna 13 and one galvanically connected to it planar inverted L antenna 14 exists.
  • the antenna configuration is fed via the feed point 15.
  • FIG. 4 shows an embodiment of an inventive Multi-band antenna, in which, in contrast to that in FIG. 1 Multiband antenna shown an additional separate ground plate 16 is provided. Because under normal circumstances Mass ratios within a radio-operated communication terminal are not always fully predictable Mass plate 16 for defined mass ratios with respect to the multi-band antenna. Between the ground plate and the device ground one or more connections can be provided his.
  • FIGS 5a to 5m show a small sample selection of differently designed and linked together Types of antennas according to the present invention. This Selection is by no means restrictive. The same applies here that the Any combination of the coupled antenna types can be.
  • the radiating element can be wavy, as shown in FIG is formed, or, as shown in FIG. 8, rectangular meandering.
  • FIG. 7 shows, by way of example, that it goes without saying also the ground plate of the shape of the radiator element can adjust.
  • the multi-band antenna is not 100 percent parallel for metallic EMC shielding of the radio-operated communication terminal runs, but at one or several places a larger distance between the antenna and the metallic EMC layer. This is an example shown in Figure 9.
  • the increase in distance can, for example also occur at the feed point of the antenna.
  • FIG. 12 is a perspective representation of a principle partially shortened antenna configuration according to the present Invention shown.
  • the antenna configuration shown consists of a compressed microstrip antenna 17 and a planar inverted-F antenna 18 which are connected to each other are electrically connected, the supply and the connection with ground via the planar inverted-F antenna.
  • parts of the actual radiator elements point the two antennas have different heights or slopes on.
  • the invention Antenna the problem underlying the invention resolves that none, one or more planar inverted-F antennas and / or none, one or more planar inverted-L antennas and / or none, one or more microstrip (patch) antennas by coupling to one another to form an antenna system get connected.
  • microstrip (patch) antennas by coupling to one another to form an antenna system get connected.
  • the present invention is not limited to this.
  • the antenna structure is only fed at one point.
  • This preferably has a planar inverted-F structure or a planar inverted L structure.
  • the coupling between the individual radiator elements can be capacitive, inductive, blasted or be galvanic. Due to the type and number of couplings various parameters of the antenna can be set. For example, are the dimensions for the planar inverted-F antenna and the length of the microstrip antenna the same, the radiation frequencies behave like approx. 1: 2. This can be used as a GSM-PCN antenna.
  • This planar antenna structure requires one feed and one or several ground connections, which can be of any shape can do certain antenna properties set.
  • the connection points for the supply indicated in the drawings and ground connection can and must also be interchanged not necessarily at the edge or a corner of the spotlight structure lie. They can be positioned so that for all operating frequency ranges a desired impedance behavior is set becomes.
  • the antenna can have its own ground plate or else the metallic parts and surfaces of the radio-operated communication terminal use as a ground plate.
  • the possibly additional Earth plate can be shaped as desired and does not necessarily have to be adapted to the shape of the radiator element his.
  • the individual parts of the radiator element can be different Heights, e.g. through cranking or inclines of the ground plane.
  • the antenna can also be adjusted by suitable vertical Structures to be compressed or by suitable Folding can be shortened.
  • the type of folds and / or upsets can be executed arbitrarily and can in different technologies can be realized. It can the radiator element alone, but also the associated ground plane be structured accordingly.
  • the corresponding shape the radiation properties of the individual radiator elements further change or improve or the antenna adapt to the geometry of the housing. In this case it is e.g. to name grading, slits, tapering, change of Spotlight height above the ground surface.
  • the multiband antenna according to the invention is that individual radiator parts, which are used for a planar inverted-F antenna, for example, can also be used for radiation as an inverted-L antenna or as a microstrip antenna. Any combination of radiator elements is possible, and consequently additional resulting antenna structures are possible. These enable radiation in further frequency ranges or can be used to further improve one or more radiation behavior.
  • the space or volume requirements can be kept small due to the multiple use of radiator parts.
