Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the upper portion of the side frame is used as the antenna, then the antenna structure is simplified and integrated into the housing, but the radiation efficiency deteriorates leading to spotty NFC communication
Solution Approach 1:
The housing is divided into multiple conductive portions (side frame and rear cover) that function as separate antenna elements. The side frame includes first and second conductive portions, while the rear cover includes third and fourth conductive portions, creating multiple radiation sources distributed across the device surface to improve overall antenna performance and communication reliability
Solution Approach 2:
The antenna function is merged with the housing structure itself. The conductive portions of the side frame and rear cover are integrated into the housing design, eliminating the need for separate antenna components while maintaining aesthetic appearance and structural integrity
2Device complexity
If the upper portion of the side frame is used as the antenna, then the antenna is integrated into the housing, but the radiation pattern becomes concentrated on the uppermost portion reducing communication coverage
Solution Approach 1:
The antenna radiation is extended from a single upper portion location to multiple dimensions across the device surface. By distributing conductive portions across the side frame and rear cover, the radiation pattern spreads across multiple spatial zones, improving coverage area and adaptability for wireless communication in various orientations

AI summary
Embodiments of the present disclosure relate to an electronic device including a housing antenna formed from a conductive material. At least parts of a side member and a rear cover that constitute the housing of the electronic device are used as an antenna. Accordingly, radiation patterns generated by this antenna are formed on the rear surface of the electronic device as well as at the upper portion of the electronic device. It is therefore possible to perform wireless communication with higher accuracy. Other embodiments are also possible.
