Question

Quizplus · Accepted Answer

Antennas are passive conductors that do not generate power themselves. They receive or transmit electromagnetic waves through the conductive elements of the antenna.

Option A is incorrect as antennas are passive and they do not generate the power they use to transmit.

Option C is incorrect as antennas have two connection points, one for transmitting and one for receiving, and they are not necessarily connected to the ground plane.

Option D is incorrect as IR (infrared radiation) is a form of electromagnetic radiation, but it is not directly related to antennas.
