An antenna is a device that converts electrical energy into electromagnetic waves and vice versa. It plays a vital role in transmitting and receiving electromagnetic signals, such as radio waves, microwaves, and other forms of electromagnetic radiation. Wave propagation, on the other hand, refers to the way electromagnetic waves travel through different mediums, including air, water, and solids.
