AI Technical Summary
The existing folding screen electronic devices have poor antenna performance in the folded state, resulting in low antenna efficiency.
An electronic device is designed, which includes a first body part and a second body part. The second body part can be folded or expanded relative to the first body part. By forming a second metal branch on the second body part as a parasitic radiator, the second gap and the second coupling gap are located in the orthoprojected area of the first gap and the first coupling gap, thereby reducing the influence of the metal frame on the antenna radiation performance.
When the electronic device is in a folded state, the radiation efficiency and bandwidth of the antenna are improved, and the impact of metal frames on antenna performance is reduced.
