SLRC610: Single Reader Multiple antenna design

[akashjain2996]

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?

Hello Akash,

>>multiple antennas?

Yes, feasible.

>>Is it fine to use RF switches and then power on each antenna one by one?

RF switches, yes, feasible.

>>Does the switch affect the antenna matching network?

yes. But you should ensure all antennas are the same parameters.

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

No read-made solutions for your application. you will have to design it yourself.

Have a nice day!

Hi Akash,

   you can contact skyworks ,whose web is Skyworks | Home , I searched "RF switch" on the home page , and got many kinds of product, then found :

Probably the RF switch should be OK, but I can't ensure it, you had better contact skyworks' engineer and get more help on your application.

Have  a nice day!

Best Regards,
