I have two 3G ceramic antennas operating in 850, 1900, and 2100 MHz band that are mounted in vertical and horizontal plane to compensate polarization diversity. Two antennas are 10 mm apart. I heard that when antennas stay closer than lambda/2, there will be a coupling effect deducts antenna performance.
But how does the coupling effect impact on antenna performance?
If there is other effects of antenna proximity, please tell me. I know that two antennas should stay apart more than lambda/2, but with limited space I can't do that. So I would like to get suggestions about the effect that will happen to antennas. How to measure that effect? Can I measure ISOLATION between two antennas? If yes, please advice me.
I appreciate every comments.
