Household appliance, household appliance arrangement and cooking system

摘要

The invention describes an easy-to-manufacture wide-band antenna arrangement 100 and a kitchen appliance 300 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 360 communicate with the kitchen hob, e.g. for improving cooking results.
