Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manufacturers design different antenna devices for different frequency bands, then the antenna device can be optimized for specific frequency bands, but the design process becomes more complex and manufacturing costs increase
Solution Approach 1:
The patent implements a universal antenna device that can operate across multiple frequency bands (sub-6GHz and millimeter wave) using the same structural design. The antenna device includes a substrate with a radiation element and a ground element that can support both frequency ranges, eliminating the need for separate antenna designs for different frequency bands. This multi-functional approach allows a single antenna device to replace what would traditionally require multiple specialized antenna designs.
2Reliability
If manufacturers design different antenna devices for different frequency bands, then the antenna performance can be tailored to specific requirements, but manufacturing costs increase
Solution Approach 1:
The antenna device employs a universal design that covers multiple frequency bands including sub-6GHz and millimeter wave ranges, allowing manufacturers to use the same antenna structure for different electronic products regardless of their specific frequency band requirements. This reduces per-unit manufacturing costs through economies of scale and simplifies the supply chain by standardizing the antenna component.
Solution Approach 2:
The patent utilizes parameter changes in the radiation element and ground element configurations to enable operation across different frequency bands. By adjusting geometric parameters such as element dimensions, spacing, and patterns, the same antenna structure can be optimized for different frequency ranges without requiring complete redesign, thereby maintaining manufacturing efficiency while achieving frequency-specific performance.
3Reliability
If antenna devices are redesigned for different electronic products, then the design can be optimized for specific product requirements, but time is wasted and productivity decreases
Solution Approach 1:
The patent creates a universal antenna device that can be applied across multiple electronic products without requiring product-specific redesigns. The antenna structure is designed to accommodate various form factors and frequency band requirements through parameter adjustments rather than structural redesign, significantly improving design efficiency and enabling rapid deployment across different product lines.

AI summary
An antenna device includes a first substrate, a second substrate, a radiation portion and a cross-shaped exciter. The first substrate has a first top surface. The first substrate is stacked on the second substrate. The second substrate has a second top surface and a bottom surface. The second top surface faces away from the bottom surface. The radiation portion is disposed on the first top surface, and includes a first radiation component, a second radiation component, a third radiation component and a fourth radiation component. The first radiation component and the fourth radiation component are arranged on the first top surface symmetrically along a diagonal of the first top surface. The second radiation component and the third radiation component are arranged on the first top surface symmetrically along another diagonal of the first top surface. The cross-shaped exciter is disposed on the top surface.
