Is This An Antenna?

I work a lot with RF stuff at work, and a major thing in RF is impedance matching networks.

Does this look like a printed antenna to you? I did to me.

My first guess was it performed some form of energy harvesting.



My wife said this patch relieved pain as well as her TENS unit.

I ground myself at night for pain relief and more peaceful sleep. My wife does too. Once she started grounding she stopped needing her CPAP machine.

May not be an antenna per se, but it could be some sort of frequency selective surface something like this:



Although the pattern is not something I recognize. I'm calling it BS, but hey, it if works for you, why not?
