Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate antenna structure is used for 5G sub-6GHz and Wi-Fi 6 frequencies, then communication stability is improved, but device complexity and space occupation increase
Solution Approach 1:
The patent combines 5G sub-6GHz and Wi-Fi 6 antenna elements into a single integrated antenna structure. The antenna includes a ground electrode, feed electrode, and multiple radiation elements that operate across both frequency ranges simultaneously, eliminating the need for separate antenna structures while maintaining communication stability through coordinated design of the radiation elements for dual-frequency operation
2Area of stationary object
If antenna elements are arranged closely to reduce device size, then miniaturization is achieved, but signal interference between elements increases
Solution Approach 1:
The patent applies local quality by designing different radiation elements with specific geometric configurations optimized for their respective frequency operations. The antenna includes elements with different lengths and orientations (e.g., first radiation element along major axis, second radiation element along minor axis) that are locally optimized to minimize mutual interference while enabling compact arrangement through the use of a shared ground electrode structure
3Adaptability or versatility
If multiple antenna elements are used to support multiple frequencies, then frequency adaptability is improved, but manufacturing complexity increases
Solution Approach 1:
The patent implements universality by designing a single antenna structure that serves multiple frequency functions. The ground electrode and feed electrode configuration, combined with multiple radiation elements of different dimensions, enable the antenna to operate across 5G sub-6GHz and Wi-Fi 6 frequency ranges using a unified manufacturing process, eliminating the need for separate antenna assemblies for different frequencies

AI summary
An ultra wide band (UWB) antenna in various embodiments can comprise: a dielectric substrate; a first conductive layer arranged on one surface of the dielectric substrate; and a second conductive layer arranged on the other surface of the dielectric substrate. The first conductive layer can comprise: a first patch antenna having a structure of receiving a first UWB signal that has a first frequency band of which the polarity direction of the electric field is a vertical linear polarization, and a second UWB signal that has a second frequency band of which the polarity direction of the electric field is a horizontal linear polarization; a second patch antenna which is arranged to be spaced from the first patch antenna in a first direction and which has a structure that is the same as that of the first patch antenna; a third patch antenna which is arranged to be spaced from the first patch antenna in a second direction perpendicular to the first direction and which has a structure that is the same as that of the first patch antenna; a first transmission line for connecting a connector and the first patch antenna; a second transmission line for connecting the connector and the second patch antenna; and a third transmission line for connecting the connector and the third patch antenna. The second conductive layer can comprise a ground pattern, which overlaps on the first patch antenna, the second patch antenna, the third patch antenna, the first transmission line, the second transmission line, and the third transmission line, when facing the second conductive layer in a third direction that is perpendicular to the first direction and the second direction. Other various embodiments are possible.
