An antenna is a device that converts the AC electrical energy at it's
teminals into electromagnetic energy which radiates from the antenna

into AC electrical energy at it's terminals.

Radiates waves or photons or something else?

A rectenna is simply an antenna with something that acts as a diode at
it's terminals to convert the AC to DC.

In AC electrons oscillate. In DC electrons are flowing for ages.
Where they come from?
