Engineering Contradiction Analysis
1Ease of manufacture
If the antenna structure is inclined only with the structure of the housing itself, then the assembly is simplified, but it is difficult to set a desired tilting angle due to mold error
Solution Approach 1:
The antenna support structure is divided into multiple components: a housing, a separate support bracket, and an antenna module. The support bracket is detachably connected to the housing and can be independently adjusted, allowing the tilting angle to be precisely set without being constrained by housing mold errors. This segmentation enables independent optimization of each component's manufacturing precision.
Solution Approach 2:
A support bracket is introduced as an intermediary component between the housing and the antenna module. This bracket serves as a mediator that can be precisely manufactured and adjusted independently, thereby achieving accurate tilting angle control without directly modifying the housing structure. The bracket acts as a flexible interface that decouples the antenna positioning from the housing's manufacturing tolerances.
2Reliability
If the antenna structure is tilted to improve radiation performance, then connectivity is enhanced, but it becomes necessary to consider complex connectivity with the device substrate
Solution Approach 1:
The support bracket is designed with adjustable and detachable features, allowing the antenna module to be dynamically positioned at the optimal tilting angle for radiation performance. The bracket can be easily assembled and disassembled, enabling flexible adjustment of the antenna's orientation relative to the device substrate without permanent structural modifications, thus simplifying connectivity considerations.
Solution Approach 2:
The support bracket is pre-configured with mounting features and connection interfaces that are designed in advance to accommodate the tilted antenna configuration. By preparing the bracket structure beforehand with appropriate attachment points and orientation, the complexity of connecting the tilted antenna to the device substrate is reduced, as the connection geometry is already optimized during bracket design rather than being imposed during final assembly.

AI summary
An electronic device includes a housing, and an antenna structure disposed in the inner space of the housing. The antenna structure includes a substrate including a first surface, a second surface facing away from the first surface, and side surfaces surrounding a space between the first surface and the second surface. At least one antenna element is disposed to form a beam pattern in a direction in which the first surface is oriented, and at least one bracket is disposed in the inner space and configured to support the substrate such that the first surface is tilted to a predetermined angle with respect to a first direction. A wireless communication circuit is disposed in the inner space and is configured to form, via the at least one antenna element, the beam pattern in the direction in which the first surface is oriented.
