Ah - we're back to the rectenna which is defined in Wiki thus "A simple
rectenna element consists of a dipole antenna with a diode connected
across the dipole elements".

Here you are the simple:

Are the dipole elements symmetrical?

Yes

It seems that one of them is a counterpoise.

Why? I see symmetrical elements.

What you can also see here is that this is another example of what
I wrote earlier: there is a circle in the schematic starting at the
diode where you can go around with DC current and end at the same
point.
This circle is where the DC current flows, not from the elements into
the air.
