Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex antenna structures with multiple components are used to achieve wideband transmission and reception, then communication performance is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent combines the antenna element and ground plane into a single monolithic printed circuit board structure. The antenna element is directly printed on the PCB substrate with the ground plane, eliminating the need for separate antenna components and complex assembly processes. This integration maintains wideband communication performance while significantly reducing device complexity and manufacturing difficulty.
Solution Approach 2:
The patent replaces traditional mechanical antenna structures with a printed circuit board-based antenna element. Instead of using separate metal components and mechanical assemblies, the antenna is created through PCB printing processes, substituting mechanical construction with electronic manufacturing techniques. This achieves both performance and manufacturing simplicity.
2Ease of manufacture
If traditional antenna designs are used in kitchen environments, then manufacturing is straightforward, but reliability deteriorates due to high temperature and greasy conditions
Solution Approach 1:
The patent uses a printed circuit board as a composite structure that integrates the antenna element, ground plane, and mounting substrate into a single robust unit. The PCB material provides both electrical functionality and mechanical robustness, enabling the antenna to withstand high temperatures and greasy kitchen environments while maintaining ease of manufacture through standard PCB fabrication processes.
3Adaptability or versatility
If wideband transmission and reception capabilities are implemented, then communication versatility is improved, but manufacturing complexity increases
Solution Approach 1:
The patent achieves wideband transmission and reception by carefully designing the geometric parameters of the antenna element and ground plane on the PCB. By optimizing dimensions, shapes, and configurations during the design phase, the antenna provides broad frequency coverage without requiring complex manufacturing processes. The wideband capability is achieved through parameter optimization rather than structural complexity.

AI summary
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.
