Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to design an electronic device with an antenna structure that achieves optimal signal radiation performance, particularly in high frequency bands where the wavelength is short, leading to strong directivity and propagation path loss.
Innovation Solution
The electronic device incorporates a specific housing structure with a support member, a non-conductive structure, and an antenna structure. The antenna is positioned between the support member and the back plate, with the non-conductive structure placed in a space surrounded by the housing components. This configuration allows for directional beam formation and adjusts the signal radiation pattern.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a small-sized antenna is used for millimeter band communication above 20 GHz, then the device size is reduced, but signal radiation performance is degraded
Solution Approach 1:
The patent introduces a non-conductive structure with a specific three-dimensional shape positioned adjacent to the antenna. This structure modifies the radiation pattern by utilizing spatial dimensionality to control signal propagation, thereby improving radiation performance without increasing antenna size. The non-conductive structure creates a directional beam pattern that enhances signal strength in specific directions while maintaining compact dimensions.
2Quantity of substance
If the wavelength is shortened in high frequency bands, then more antennas can be mounted in the same area, but propagation path loss increases
Solution Approach 1:
The patent applies local quality modification by positioning a non-conductive structure with specific geometric features adjacent to the antenna. This structure locally modifies the electromagnetic field distribution and radiation pattern, creating a directional beam that concentrates energy in specific directions. This reduces propagation path loss by focusing signal energy where needed, allowing effective communication even with smaller, higher-frequency antennas.
3Reliability
If a non-conductive structure with a specific shape is disposed adjacent to the antenna, then signal radiation characteristics are enhanced, but device complexity increases
Solution Approach 1:
The non-conductive structure is designed to serve multiple functions: it acts as a radiation pattern control element, provides mechanical support, and can be integrated with existing device housing components. By combining multiple functions into a single structure, the patent enhances signal radiation characteristics while minimizing the increase in overall device complexity.

AI summary
An electronic device is provided. The electronic device includes a support member, a front plate disposed on a front surface of the support member, a back plate disposed on a back surface of the support member, a non-conductive structure interposed between the back plate and an edge of the support member and fixed to the support member, and an antenna structure interposed between the back plate and an edge of the support member. At least a portion of the antenna structure may be disposed to face the non-conductive structure. In a region of the non-conductive structure, which faces the antenna structure, a separated distance from the antenna structure varies depending on a distance from a bottom surface of the support member to which the non-conductive structure is fixed.
