This time-varying fields radiate away from the antenna in space as a wave of electromagnetic field in motion. Conversely, upon receipt of the oscillating electric and magnetic fields of a radio wave that exert a force on the electrons in the antenna elements, allowing them to move, creating oscillating currents in the antenna.


Antennas can also be directive or reflective elements or surfaces not connected to the transmitter or receiver, as the parasitic elements, parabolic reflectors or horns, which are used to direct the radio waves into a beam or other desired radiation pattern. The antennas can be designed to transmit or receive radio waves in all directions (Omni-directional antennas), or send a beam in one direction, and you get some direction (directional gain antennas or high).
