Appendix C. Antenna ports operation description
CS203X-2 is a reader where the ports are switched on in time one by one.
At any time only 1 port is switched on and the RF power comes out only at
that port. The rest of the ports are turned off so that no energy comes out
from the other ports.
The Antenna should be set up 0.5 meter apart is shown as below:

Energy coming out of 1 antenna (note that CS203X-2 is switched on in
time one by one so that at any 1 moment in time ONLY 1 antenna is
turned on)
