Antenna Placement [WiFi&BT Ant + LTE Ant]

Hi,

I have a design to use WiFi&BT Module and LTE Module in the same PCB. So I will use SMA connector for Antenna installation.

I would like to ask how far apart should I place each SMA antenna to avoid interference from other antennas?

Hi,
It is recommended the WIFI antenna and the cellular antenna be placed on both sides of the board, the farther away the better, the antenna isolation should be greater than 15db, and it should be noted that the wifi needs to choose a module with a band pass filter at 2.4G frequency.
