Array Antenna Housing Structure for Conductive Frame Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The presence of conductive portions in electronic device housings can degrade antenna radiation performance and sensitivity due to excitation currents caused by concave parts formed by engaging structures near the antenna module.
Innovation Solution
The electronic device incorporates a support member with conductive and non-conductive portions that form the lateral appearance, with openings filled with non-conductive material, allowing beam radiation through these openings to prevent degradation of antenna performance and protect against external impacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a conductive portion is placed near the antenna module to reinforce rigidity and create appearance, then structural strength and aesthetic quality are improved, but antenna radiation performance and sensitivity are deteriorated due to excitation currents from concave parts
Solution Approach 1:
The housing is segmented into conductive and non-conductive portions, with the non-conductive portion specifically positioned near the antenna module to prevent excitation currents while the conductive portion provides structural strength and appearance in other regions
Solution Approach 2:
Different regions of the housing have different material properties: non-conductive material is used locally near the antenna module to prevent interference, while conductive material is used in other regions for strength and aesthetic purposes

AI summary
An electronic device is provided. The electronic device includes a front cover, a rear cover, an array antenna, and a support member. The support member includes a conductive first portion forming a lateral appearance of the electronic device, a second portion adjacent to the array antenna, the front cover, and the conductive first portion, and having at least one opening filled with a non-conductive material, and a third portion including a non-conductive material and disposed adjacent to the array antenna, the rear cover, and the conductive first portion. The conductive first portion is exposed to an outside of the electronic device, and the second and third portions are hidden by the front and rear covers. A beam formed by the array antenna is radiated to the outside through the at least one opening and the third portion.
