Definitions
- Antenna device for radio-based electronic devices for radio-based electronic devices
- the invention relates to an antenna device according to the term Ob of claim 1.
- metallized or metallic housings are used, or housings that are at least partially metallized or metallic, there is the problem that an antenna device that is placed inside the housing experiences a shielding effect.
- Object of the present invention is to provide an antenna device of the type mentioned, which is functional despite a shielding effect of an electrically conductive frame or an electrically conductive housing outside the antenna device around.
- a housing having a cladding surface comprising at least a portion that is metallized or metallic and encases an inner housing volume of the housing.
- an electrically conductive connection is made from a first to a second location of the metallized or metallic mantle surface.
- the first and the second location are selected in such a way that within the encased housing volume by the electrically conductive connection between the first and the second place a radio frequency resonance space is separated, which has a radio parallel resonance, which is tuned to an operating frequency of an underlying electronic device.
- Such an antenna device has the advantage that it can be used, even if or just because the mantle surface of the housing of a respective radio-based electronic device is at least partially metallized or metallic.
- the separated resonance space between the above-mentioned first and second location on a radio path which is adapted to half the wavelength of the operating frequency of the underlying radio-based electronic device.
- This adaptation is important for obtaining the desired parallel resonance in the relevant resonance chamber.
- the radio frequency energy to be radiated or to be received via the antenna device can be coupled in or out of the said separated resonance space in an advantageous manner in conventional technology, galvanically, inductively or capacitively.
- the electrically conductive connection between the first and the second point can be realized in an advantageous manner without problems by a dedicated conductor or by an electrically conductive surface of a printed circuit board.
- the antenna device can be used as a component of a radio-based electronic straight line. tes can be made, which is a radio-based communication terminal.
- the antenna device can be used to creatively design completely new radio-based electronic devices.
- FIG. 1 shows a first embodiment of the invention in a schematic, three-dimensional representation
- Figure 2 shows a second embodiment of the invention in a schematic, three-dimensional representation
- Figure 3 shows a first Ankopplungsbeispiel for an antenna cable in an article according to the figure 1
- FIG. 4 shows a second coupling example for an antenna cable in an article according to FIG. 1
- FIG. 5 shows a third coupling example for an antenna cable in an article according to FIG. 1.
- the communication terminal 1 has a housing 2, which comprises a mantle surface 3, which is metallic or metallised at least in a section 4.
- this metallization can be realized for example by a chrome plating.
- the relevant section or the relevant piece of the housing 2 is solid metallic, for example, by a metallic die cast part formed.
- the metallized or solid metallic housing 2 forms an electrically conductive frame 5, which encloses an inner housing volume 6 of the device 1.
- an electrically conductive connection 7 is made from a first to a second location 8, 9 of the metallized or metallic mantle surface 3 through the encased housing volume 6.
- Said first and second place 8, 9 are selected together in such a way that within the encased housing volume 6 by the electrically conductive connection 7 a funk- technical resonance chamber 10 is separated with a radio parallel resonance at an operating frequency of the electronic device.
- the separated resonance chamber 10 between the first and the second point 8, 9 a radio path 11 (for simplicity, only shown in Figures 3 to 5), which corresponds to half the wavelength of the operating frequency of the device 1.
- a respective connection of an antenna cable 12 with respect to the respectively separated resonance chamber 10 is shown schematically in the respective FIGS. 1 to 5.
- FIG. 3 shows in each case a connection possibility in a galvanic manner
- FIG. 4 a connection possibility in an inductive manner
- FIG. 5 a connection possibility in a capacitive manner.
- the electrically conductive connection 7 between said first and said second locations 8, 9 can be realized by a dedicated conductor (FIGS. 1 and 3 to 5) or by an electrically conductive surface (FIG. 2) of a printed circuit board 13.
- the addressed surface may be a copper layer of the printed circuit board 13, for example.
- the special conductor may be a wire or a sheet metal strip.
