Learn about the workings of an antenna.
Antennas are used to receive electromagnetic waves through the air. This is converted to an electrical signal and the reverse is true. It is crucial to separate the electromagnetic waves from the origin before they are able to propagate. Wave separation is the process of accelerating or decelerating charge. This causes the magnetic field to stretch and the memory effect to take place. Therefore, an antenna can be created if an arrangement of oscillating positive and negative dipoles is made. That’s why antennas come with multiple rods, with electric current running through them. The result is that one pole becomes positive and another negative. It creates waves. Wave propagation refers to the frequency that the signal will be the same frequency that the signal generated by voltage. The antenna’s length is to be proportional to the wave’s length, which is determined by using the speed of light for the speed of the waves. The way you see it, electrons as well as their electric fields can be crucial to the function of antennas. I hope this article and video made the concept a little more manageable.
