I have electrodes to be tested their characteristics
Here is a picture of them,
And I connected them to USRPs via SMA-SMA cable
However, there is a problem!
I want to know characteristics of just CIRCLE part, except a rod part.
In my experience, this rod part acts as an antenna! Thus, I cannot
So, I make a shield around the rod part. This shield is made with
foil which is used for cooking.
And I expect that the rod part rarely sense electromagnetic wave and
only the circle part can receive a signal
The result is like this:
Result without SHIELDING
Result with SHIELDING
That’s very weird.
As my knowledge, if there is SHIELDING, the sensitivity of an antenna
But, in my experiment, this SHIELDING helps communication!
I have any idea of it. I got confused
Did I make shielding wrong?
