I recently have read about interception of wireless information, however this mentions that people can intercept the information, and then somehow the recipient also gets the information. Regardless of this context, what happens to the actual photon if it is absorbed by one antenna how can another person receive the same signal? Is it that when the photon is absorbed exciting the electron, the electron will then leap back to the lower energy state causing it to emit another photon? so the antenna acts as a receiver & transmitter? to be honest I'm confused overall in how antennas work.
