Hi Sir,

在设计上用到两个芯片,经典蓝牙用CYW20719,BLE用Apollo3,使用两根天线。在布天线的时候,需要做到多少的隔离度,这个有标准吗,还是说需要咨询天线厂?

Thanks,

Leo

Ideally, the two sets of antenna should be isolated as much as possible. One approach is to consider the polarization of the two antenna. If they are positioned such that their main beams are orthogonally polarized, then it will be ideal. You will have to refer to the antenna datasheet for the direction of the main beam.

You can also positioned them about a quarter wavelength apart.
