A device used to radiate electromagnetic energy into space or to collect this energy from space?

An antenna is the interface between a radio system and free space. It converts electrical energy into electromagnetic waves for transmission and, when receiving, converts incoming waves back into electrical energy for the receiver. That dual role—radiating energy into space and collecting energy from space—fits the description perfectly. A transmitter creates the energy but relies on an antenna to emit it; a waveguide passes energy between components but isn’t the radiating/receiving element itself; a charger stores energy and isn’t involved in radiating or receiving EM waves. So the device described is the antenna.
