I have to design a model, where 2 antennas, (PCB Loop) are placed on the same PCB. One is used as energy antenna to power the tag and the other is used to transmit and recieve data from tag.

I have read some documents and found the placing the two antennas orthogonally minimises multipath.

I was wondering if I could some help on how to place two antennas on the same PCB with no disturbance to each other?
Thank you
 

Hello

I think if you place the two antennas orthogonally each other but one is Top and the other one in bottom side of the PCB trying to have the feed points more or less at the same position in order to "share" the antenna nulls and avoid the disturbance.

Also, you can control by software when one antenna operates and when the other one.

Thank you! I am going to read more on the lines of your suggestion
