Abstract

The invention describes an easy-to-manufacture wide-band antenna arrangement (100) and a kitchen appliance including this antenna arrangement. A resonating part of any antenna arrangement has a flat shape, its outer edges have an elliptical curvature and a coaxial cable is located at a feed in a slit in the middle of the resonating plate. The resonating plate is parallel to a ground plane 105, and together those parts form a planar inverted-F antenna. Such an antenna is useful in combination with a kitchen hob and sensor applications that wirelessly communicate with the kitchen hob, e.g. for improving cooking results.

Claims

1. Antenna arrangement comprising:

a ground-connecting part at one end,

a shape part distal from the ground-connecting part with a curvature,

a slit between the curvature, and

a feed located within the slit.

2. Antenna arrangement according to claim 1, wherein the curvature is located at an outer edge.

3. Antenna arrangement according to claim 1, wherein the curvature has an elliptical shape.

4. Antenna arrangement according to claim 1, wherein the feed is coaxial.

5. Antenna arrangement according to claim 1, wherein the feed is connected on a tongue in the slit.

6. Antenna arrangement according to claim 1, wherein the slit extends in a longitudinal direction of the antenna arrangement.

7. Antenna arrangement according to claim 1, wherein the slit has parallel edges and/or is located in the middle of the shape part.

8. Antenna arrangement according to claim 1, having a flat shape and/or a ground plane connected to the ground-connecting part.

9. Antenna arrangement according to claim 1, wherein the shape part has a trapezoidal part next to the curvature.

10. Antenna arrangement according to claim 1, having a rectangular part next to the ground-connecting part.

11. Antenna arrangement according to claim 1, said antenna arrangement being manufactured of sheet metal.

12. Antenna arrangement according to claim 11, said antenna arrangement having a stepped shape wherein the ground-connecting part is parallel to the shape part and a rectangular part forms a right angle with both.

13. Antenna arrangement according to claim 1, said antenna arrangement being arranged as a planar inverted-F antenna with elliptically tapered resonating metallic plate.

14. Kitchen appliance comprising an antenna arrangement according to claim 1.

15. Kitchen appliance according to claim 14, comprising a wireless device adapted to communicate with the antenna arrangement.
