Solution Overview
Problem
The manufacturing of high-frequency antenna dipole radiating elements requires multiple components, leading to increased time and expense, necessitating a solution that reduces component count while maintaining or improving performance.
Innovation Solution
A unitary high band dipole antenna element with a shaped central portion and multiple shaped arm portions, configured with slots in fractal or Sierpinski carpet patterns, which are formed using progressive die techniques and can be connected to a chassis, allowing for reduced component count and efficient RF signal transmission in the 1700 MHz to 2700 MHz range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple components are used to manufacture antenna dipole radiating elements, then manufacturing precision and reliability are improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent merges multiple separate antenna components (central portion, arm portions, connecting cables) into a single unitary structure formed by progressive die techniques. This integration maintains the functional precision of multiple components while eliminating assembly complexity and reducing part count, directly resolving the contradiction between manufacturing precision and device complexity.
Solution Approach 2:
The unitary antenna element performs multiple functions that previously required separate components: the shaped central portion provides structural support and mounting, the arm portions provide RF signal transmission, and the integrated structure provides mechanical connection. This multi-functionality maintains precision while reducing overall device complexity.
2Stability of the object's composition
If multiple components are assembled to form antenna elements, then structural stability is improved, but manufacturing time and expense increase
Solution Approach 1:
The progressive die technique forms the entire antenna element (central portion, arm portions, and connection points) as a single unitary structure in one manufacturing process. This eliminates multiple assembly steps while maintaining structural stability, directly improving productivity without sacrificing structural integrity.
Solution Approach 2:
The progressive die process performs preliminary forming actions during manufacturing, creating the complete three-dimensional antenna structure with all necessary features (slots, arm portions, mounting points) already integrated. This preliminary formation of the complete structure eliminates subsequent assembly operations, resolving the contradiction between stability and manufacturing efficiency.
3Ease of repair
If traditional multi-component antenna elements are used, then ease of repair is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The unitary structure integrates all antenna components into a single replaceable unit. While individual components cannot be separately replaced, the entire antenna element can be quickly replaced as one unit, simplifying repair procedures. This approach trades internal component replaceability for reduced assembly complexity and lower manufacturing costs, resolving the contradiction between ease of repair and device complexity.
