Definitions
- the invention relates to a slot antenna arrangement according to the preamble of Patent claim 1.
- the slot antenna is used in receiving satellite signals, e.g. to Navigation, as well as in land, water and air vehicles.
- Slot antennas with radiation field coupling are suitable for such receiving antennas.
- the e.g. have a feed line on the back of a substrate (B.D.M Pozar, IEEE Trans. Antennas Prop. Vol. AP-34, no. 12, pp. 1439-1446 (1996)).
- Japanese Patent Application 0 6383923A discloses a slot antenna with one a cavity formed of a dielectric material, the slot in a conductive Wall is brought.
- the object of the invention is to provide a powerful slot antenna arrangement, with the different polarized waves are received and the easy to the Vehicle body are adaptable.
- the invention has the advantage that by the integrated switched on and off low-noise preamplifier (LNA) excellent reception performance can be achieved.
- LNA low-noise preamplifier
- Antennas are circular as well as linear due to the switchable LNA to receive polarized waves.
- the flat, mechanically robust design the antenna, as well as their invisible and aerodynamically optimal arrangement in the Vehicle body advantageous.
- the antenna 1 is introduced as a slot-shaped recess in the metallic vehicle body 2.
- the antenna is closed from the back by a cavity 3 with shallow depth.
- the cavity is filled with a dielectric, eg Teflon, polystyrene or the like.
- the low-noise preamplifier (LNA) is connected to the antenna by different lengths of leads L 1 , L 2 , so that, for example, when receiving circularly polarized waves, the addition the two rotated by 90 ° linear polarization states in the LNA takes place.
- the correct phase position of the waves is set via different lengths of supply lines L 1 , L 2 .
- the LNA is introduced into the dielectric and connected via leads L 1 , L 2 to the metallic body.
- the entire antenna introduced into the metallic body can be coated with a lacquer layer 4.
- the power supply and the decoupling of the amplified signal takes place, for example, via the lines L 1 , L 2 introduced in the dielectric.
- the lines L 1 , L 2 microstrip lines can be used. This has the advantage that the structure of the antenna in sandwich technique is possible.
- the use of coaxial cables offers the advantage that lower electrical losses occur.
- the slot-shaped antenna contour can be linear Slit, ring slot or cone-shaped slot designed are.
- FIG. 2 for example, an embodiment of a ring slot 5 is shown.
- the back cavity has a depth of eg 1mm.
- the cross-sectional area of the cavity of the antenna is ever designed according to the shape of the slot antenna, since the shape of the Resonance frequency of the antenna determines.
