AI Technical Summary
Existing wireless LAN communication modules suffer from electromagnetic radiation interference when using the USB 3.0 interface, leading to performance degradation in specific frequency bands. Traditional anti-interference methods struggle to balance simple structure, low cost, and effective interference elimination.
An interference cancellation structure, such as a resonant unit or antenna stub, is integrated with the main antenna in the wireless LAN communication module. This structure can mitigate electromagnetic interference by coupling and diverting interference energy, without adding additional shielding or filters, thus maintaining the interface layout.
It effectively eliminates electromagnetic interference from high-speed serial data interfaces, improves signal reception stability, has a simple structure, low cost, does not introduce signal insertion loss, and achieves the dual effects of interference cancellation and signal compensation.
