Here you are the simple:

Are the dipole elements symmetrical?
It seems that one of them is a counterpoise.
S*
Wiki says that a rectenna is "a dipole antenna with a diode connected across
the dipole elements".
A dipole is a balanced, symmetrical aerial and does not have a counterpoise.
I can't be responsible for you being unable to understand what
"symmetrical", "balanced" and "counterpoise" mean. I can suggest / recommend
that you acquire a reference book on aerials from the ARRL or RSGB. You'd
find them immensely helpful.
