| description | A WiFi (Wireless Fidelity) module comprises a PCB (Printed Circuit Board), a WiFi antenna and a BT antenna. The PCB comprises a mainboard ground and a clearance zone, and the WiFi antenna and the BT antenna are both arranged on the clearance zone. According to the invention, the clearance zone and a parasitic coupling unit are additionally arranged between the WiFi antenna and the BT antenna on the PCB, so that electromagnetic coupling generated between the WiFi antenna and the BT antenna is counteracted, surface wave coupling can be greatly reduced, and the isolation degree of the antenna is improved.
一种WiFi模块，该WiFi模块包括PCB板、WiFi天线和BT天线；所述PCB板上包括主板地和净空区，所述WiFi天线和BT天线均设置在所述净空区上。本发明通过在所述PCB板上的WiFi天线和BT天线之间增设净空区和寄生耦合单元，使之与原WiFi天线和BT天线之间产生的电磁耦合相互抵消，能够大幅度降低表面波耦合，从而提高天线隔离度。 |
