Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional solid wire antenna pattern is used, then the structure is simple and easy to manufacture, but the directivity is poor and image clarity is insufficient
Solution Approach 1:
The antenna conductor wire is segmented into multiple parallel element lines (e.g., 3-10 lines) with specific pitch intervals (5-300 μm). Each element line acts as an independent antenna element, improving directivity and image clarity while maintaining a relatively simple overall structure that can be manufactured using conventional printing or etching methods.
2Adaptability or versatility
If the receiving frequency is increased to improve bandwidth, then the broadband characteristic is improved, but the antenna size and complexity increase
Solution Approach 1:
The antenna employs parallel element lines with different lengths and orientations at different locations to receive various frequency bands (VHF and UHF). By optimizing the local geometry of each element line, the antenna achieves broadband characteristics without requiring a complex overall configuration, supporting both VHF (174-230 MHz) and UHF (470-862 MHz) TV broadcast frequencies.
3Ease of operation
If a mesh or polygonal micro-image element structure is used to improve directivity, then the multi-directivity is improved, but the manufacturing precision requirement increases
Solution Approach 1:
The antenna uses parallel element lines with specific controlled parameters: line width of 5-300 μm and pitch interval of 5-300 μm. By optimizing these parameters, the antenna achieves multi-directivity for receiving electromagnetic waves from different directions while maintaining manufacturability using conventional printing or etching processes, avoiding the need for extremely high manufacturing precision.

AI summary
An antenna pattern having a broad band characteristic as to frequencies and having a wide directivity, and an electromagnetic wave energy processing device having the antenna pattern, particularly a sheet-like antenna or electromagnetic wave shielding filter. A conductor wire forming the antenna pattern comprises an aggregated wire consisting of mesh or continuously polygonal micro-image element lines or parallel element lines. The element lines are 5-300 μm in line width and 5-1,000 μm in line pitch interval, or the most preferably 5-30 μm in line width and 5-150 μm in line pitch interval. The element lines are printed with printing ink or paste material mixed with conductive powder. In accordance with necessity, pressure treatment or polishing treatment and/or conductive plating with aid of eletroless plating or directly without aid of eletroless plating are performed on the printed surface.
