Definitions

  • the present invention relates to a Antenna arrangement for Bluetooth systems.
  • Bluetooth systems are used, for example, in cell phones Communication device for connecting with others Application devices, such as personal computers, are used.
  • the Bluetooth system requires an antenna to receive radio signals to send and receive. Because the size of a Cell phones is a very important factor in its design, is a miniaturization of Bluetooth antennas and one efficient use of available space The key to achieving both is cheap Performance for the antenna and an appealing Design.
  • Bluetooth antenna arrangements there are three main embodiments for Bluetooth antenna arrangements known.
  • the first is based on the technology of printed circuit boards. After that a Bluetooth antenna arrangement directly on one printed circuit board (PCB) printed.
  • PCB printed circuit board
  • This Embodiment has the disadvantage that the antenna only has a two-dimensional surface structure so that it a lot of space on the printed circuit board required and requires large dimensions of a mobile phone.
  • antennas are made from stamped and bent parts used on the base plate of the printed circuit board are arranged.
  • At this Embodiment of a Bluetooth antenna is only the Space on one side of the printed circuit board for used the antenna.
  • ceramic antennas used. Ceramic antennas small, but they need a comparatively large one free space surrounding the antennas. In addition, they are Ceramic antenna costs very high.
  • the invention is based on the object an inexpensive antenna arrangement, especially for To create bluetooth systems where the available standing space within a cell phone or one surrounding housing is used more efficiently.
  • the first part of the antenna arrangement the is printed on a printed circuit board, and the second part of the antenna arrangement, which is considered electrical conductive sheet is formed, arise both compared to the embodiment in the prior art, in which the antenna is printed only on the circuit board is, as well as compared to the embodiment, which is a stamped and bent part has significant advantages.
  • the first part of the Antenna arrangement required on the printed Circuit board comparatively much less space as a bluetooth antenna that is printed only because the second part of the antenna arrangement can be designed for the antenna arrangement overall gives a three-dimensional structure that basically compared to a two-dimensional structure is space-saving.
  • the available space can be used more efficiently within a mobile phone, because on both sides of the printed circuit board parts of the antenna arrangement can be arranged.
  • the second part of the antenna arrangement is preferred as Stamped-bent part designed so that a three-dimensional Structure of the antenna arrangement as a whole is ensured. At least a section of the second part of the Antenna assembly can be printed out of plane Circuit board run.
  • the second part of the antenna arrangement from a contact point the printed circuit board first in substantially perpendicular to the printed circuit board and then essentially parallel to the printed one Scarf county board.
  • the second part which is designed as sheet metal the antenna array from the edge of the printed Circuit board out towards the inside of the printed circuit board can run.
  • the Antenna arrangement overall is preferred in one corner of the printed circuit board arranged.
  • FIG. 1 there is one in a corner printed circuit board G1 a first part A1 one Antenna arrangement for a Bluetooth system arranged. On a contact point P1 is the antenna arrangement to a High frequency circuit on the printed circuit board G1 connected.
  • the first part A1 of the antenna arrangement is printed on the Printed circuit board G1.
  • a contact point P2 of the first part A1 provided the antenna arrangement of a contact point P3 assigned to a second part A2 of the antenna arrangement is.
  • the two parts A1, A2 are the Antenna arrangement shown pulled apart. in the assembled state are the two contact points P2 and P3 electrically connected and the second Part A2 of the antenna arrangement is on the printed one Circuit board G1 attached.
  • the second part A2 of the antenna arrangement runs from the edge the printed circuit board G1 in the assembled Condition of the antenna arrangement initially essentially perpendicular to the plane of the printed circuit board G1. Is at a distance from the printed circuit board G1 the second part A2 of the antenna arrangement, which is a metallic stamped and bent part is involved, for example in the right one Angle bent so that one leg of the second part A2 the antenna arrangement substantially parallel to that printed circuit board G1 runs.
  • the antenna arrangement detects Figure 1 at a frequency of about 2440 MHz Reflection minimum so that the antenna arrangement for Bluetooth applications is suitable, the low Reflection coefficients between 2400 and 2500 MHz require.
