Hello, I've been reading up on this topic and have a couple of questions. This videos shows what I am referring to:
1. What makes the electromagnetic waves from a dipol antenna spread out? There would have to be some type of force that pushed them outwards, right?
2. When the electromagnetic waves do spread out, is there a sweet spot for maximum intake of the waves or is it pretty much homogenous disregarding if someone gets the signal from the middle, below or near the top (talking about far distances from the dipole)?
3. Does the illustration from the video prove that dipole antennas are electromagnetic waves or does it explain that dipole antennas are electromagnetic waves?
4: The B field: is the B-field strongest in the middle or homogenous throughout the antenna? This question refers a bit to question 2. So it would essentially look like:
but without the sharp edges and in 3D it would be a circular shape.
