Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If professional installation CPE products with higher gain antennas are used, then antenna gain is improved, but device size increases
Solution Approach 1:
The patent transitions from a planar antenna layout to a three-dimensional stacked configuration. Multiple antenna elements are arranged in vertical layers (first antenna elements on the circuit substrate, second antenna elements on the antenna cover), utilizing the Z-axis dimension to achieve higher gain without increasing the device's footprint area.
Solution Approach 2:
The patent implements a nested antenna structure where antenna elements are embedded within the device housing layers. The first antenna elements are integrated into the circuit substrate layer, while second antenna elements are positioned in the antenna cover layer, creating a compact nested arrangement that maximizes space utilization.
2Adaptability or versatility
If different antenna structures are integrated to meet varying requirements, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent creates a universal antenna structure that can support multiple antenna elements with different configurations within a single integrated design. The stacked arrangement allows different antenna types and patterns to coexist, enabling the device to meet varying antenna requirements through one multi-functional antenna system rather than multiple separate structures.
Solution Approach 2:
The patent divides the antenna system into distinct segments (first antenna elements and second antenna elements) that can be independently configured and optimized. Each antenna element group can be designed with specific characteristics, allowing flexible adaptation to different communication requirements while maintaining overall system integration.

AI summary
A wireless communication device is provided. The wireless communication device includes a circuit substrate, an antenna cover, a first antenna array and a first power divider. The first antenna array is arranged between the circuit substrate and the antenna cover. The first antenna array includes two first antenna elements and two second antenna elements. The first antenna elements are disposed on a first surface of the circuit substrate. The second antenna elements are arranged on the antenna cover and correspond to the first antenna elements, respectively. Each of the second antenna elements and a corresponding one of the first antenna elements are separated from and coupled to each other. In response to the two first antenna elements being fed with a first signal provided by a signal source from the first power divider, the first antenna array is configured to generate a radiation pattern having a first polarization direction.
