An easy-to-manufacture wide-band antenna arrangement and a kitchen appliance including this antenna arrangement are provided. A resonating part of the 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, 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.
