SLRC610: Single Reader Multiple antenna design

Hi,

We are using SLRC610 for one of our inventory management application using ISO15693. Inorder to increase the reading range we are planning to use multiple antennas (two or four) with one reader.

 

Is it fine to use RF switches and then power on each antenna one by one? Does the switch affect the antenna matching network? Again, can you advice the placement of the switch i.e, before (may require multiple tuning network) or after the matching network (requires single tuning network). Note: similar antennas will be used.

 

Is there any reference design matching the requirement or can you suggest a suitable RF switch to connect multiple antennas?
