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.

First claim

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.
