Hello,
Can someone tell me if it is necessary to termintate Port 2 of the VNA with a 50ohm impedance when measuring S11 of an Antennae?
If this is the case then what is the reason behind this?
I am trying to measure the reflected wave when a signal from Port 1 is reflected back to the source. Surely simply isolating port 2 by distance from the circuit being measured is sufficient as opposed to going to the trouble of terminating port 2 in a 50ohm impedance.
