Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a dipole antenna is designed to support multiple frequency bands (2.4 GHz, 5 GHz, and 6 GHz), then the adaptability of the antenna is improved, but the device complexity increases
Solution Approach 1:
The patent applies multi-functionality by designing a single dipole antenna structure that can operate across three frequency bands (2.4 GHz, 5 GHz, and 6 GHz) simultaneously. The radiator is configured with specific length ratios and segmentation that enable it to resonate at multiple frequencies, allowing one antenna to perform the function of what would traditionally require multiple antennas or complex multi-band designs.
Solution Approach 2:
The patent segments the radiator into multiple sections with specific length ratios (first section to second section ratio between 0.8-1.2, second section to third section ratio between 0.6-0.8). This segmentation allows different portions of the radiator to resonate at different frequencies, enabling multi-band operation while maintaining a relatively simple overall structure. The Balun line is also segmented into multiple sections that correspond to the radiator segments.
2Ease of manufacture
If the antenna structure is simplified for ease of fabrication, then the ease of manufacture is improved, but the manufacturing precision may be compromised
Solution Approach 1:
The patent specifies precise parameter ranges for the radiator sections (length ratios between 0.8-1.2 and 0.6-0.8) and the Balun line sections to achieve optimal multi-band performance. These parameter specifications provide clear manufacturing guidelines that balance ease of fabrication with the precision needed for accurate resonant frequencies. The defined ranges allow for manufacturing tolerance while ensuring functional performance.

AI summary
A dipole antenna comprising a dielectric carrier board, a radiating structure, and a coaxial cable is disclosed. The dielectric carrier board includes a carrier board surface. The radiating structure is arranged on the carrier board surface and includes a first radiator, a second radiator, and a Balun line. The first radiator includes a first short segment and a first long segment, arranged side by side on one side of the Balun line, with the first long segment extending away from it. The second radiator includes a second short segment and a second long segment, arranged side by side on the other side of the Balun line, with the second long segment extending away from it. The Balun line connects the first and second short segments. The inner conductor of the coaxial cable connects to the second radiator.
