Definitions

• the invention relates to an antenna for DVB-T reception according to the preamble of claim 1.
• Receivers for DVB-T reception generally have rod-shaped antennas provided on the receiver, for example connected to an interface, which must have a certain length and a certain diameter in accordance with the received frequency spectrum.
• Common rod-shaped antennas have a length of around 12 to 13 cm on.
• the object of the present invention is to provide an antenna that is improved and easy to manufacture.
• a plate-shaped flat antenna is proposed according to the invention.
• the total area of the antenna is preferably so large that it corresponds to the surface of a conventional rod antenna for the frequency transmission range in question of a corresponding DVB-T standard.
• the plate-shaped flat antenna can be provided with tab-shaped edge sections which improve the adaptation.
• the plate-shaped flat antenna in the manner of a printed circuit board, which is provided on at least one surface side with a conductive layer which forms the antenna receiving surface.
• a corresponding interface in the form of a plug or a socket can then also be formed on this printed circuit board-shaped base material of the antenna in order to connect the antenna thus formed to a corresponding plug connection on the receiver itself.
• the receiver itself or parts of the receiver housing can otherwise be used as a counter surface.
• Figure 1 is a schematic full-surface side view of the DVB-T antenna according to the invention.
• Figure 2 a corresponding representation in the front view of the antenna, as it is attached to a rear side of a receiver;
• FIG. 3 a side view offset by 90 ° of the antenna connected to the receiver in FIG. 2.
• a plate-shaped flat antenna 1 is shown in the drawings. This can consist of a conductive metal plate or sheet. It can also be produced from an insulating material carrier, for example a circuit board-shaped carrier material 11, on which a metallically conductive layer 3 is formed on at least one side.
• the plate-shaped flat antenna is in principle rectangular. In the exemplary embodiment shown, it has two coupling areas 7 to the left and right to a vertical axis of symmetry 5 in the lower left and right areas to the rectangular shape 6 of the antenna 1, which lead to an enlargement of the entire antenna area.
• a connector assembly 13 which is electrically connected to the large antenna Feidabites 9 via an electrical connection line 15.
• the plate-shaped flat antenna 1 formed in this way can be plugged with its plug device 13, for example, into a corresponding plug or socket arrangement 21 on the back of a receiver 23.
• the plate-shaped antenna 1 is not only held mechanically by the plug device, but also electrically connected to the receiver 23.
• the size of the antenna area is measured so that it corresponds approximately to the surface of a conventional rod antenna for the frequency transmission range in question.
• a conventional rod antenna has, for example, a length of approximately 80 to 90 mm and a diameter of 8 to 9 mm up to a length of 15 cm and a diameter of almost 15 mm.
• the antenna area can then have values of 1000 mm 2 to 8000 mm 2 , for example, especially if the antenna is operated in the DVB-T transmission range from 470 MHz to 872 MHz. If you are thinking of expanding the transmission range in the direction of the VHF range, the dimensions could be even larger.
• the antenna is not plugged directly onto the receiver, but is instead placed and / or plugged onto a separate pedestal.
• the antenna can also be provided with a fixed base.
• This base can include, for example, an amplifier that is connected to the receiver via an antenna connection cable and is supplied with energy from there.
• the antenna can be set up or attached separately from the receiver and is then connected to a receiver via an antenna cable or in the manner of a repeater.
• the antenna has been described for the case that the antenna element is completely flat and flat. If necessary, however, it may also be possible for the antenna to have a spherical curvature at least slightly, for example also a slight cylindrical curvature about at least one axis. However, the longitudinal and transverse extension of the antenna element, which is in itself flat and planar, is much larger in both directions of extension of the plane or slightly curved antenna element than its possibly slight extension transversely to this plane.
