Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple antennas are equipped in wireless devices to operate at both 2.4 GHz and 5 GHz, then transmission rate and transmission range are improved, but interference between antennas operating at different frequency bands increases due to limited disposition space
Solution Approach 1:
The patent applies dimensionality change by orienting the first and second radiating elements in perpendicular planes. The first radiating element is substantially parallel to a first plane while the second radiating element is substantially parallel to a second plane that is perpendicular to the first plane. This spatial arrangement in different dimensions reduces electromagnetic interference between the two frequency band antennas while maintaining compact form factor.
Solution Approach 2:
The patent segments the antenna system into distinct radiating elements for different frequency bands. The first radiating element is configured for 2.4 GHz operation while the second radiating element is configured for 5 GHz operation. This segmentation allows each element to be optimized for its specific frequency band while minimizing mutual interference through the perpendicular plane arrangement.
2Productivity
If antennas operate at 5 GHz frequency, then data transmission rate is improved, but transmission range is reduced due to high scattering effect at high frequency
Solution Approach 1:
The patent implements multi-functionality by enabling the wireless device to operate at both 2.4 GHz and 5 GHz frequency bands using the antenna system. The first radiating element handles 2.4 GHz operations for extended range, while the second radiating element handles 5 GHz operations for high data rates. This universal antenna design allows the system to dynamically select or combine frequency bands to achieve both high transmission rate and long transmission range.
