Findings about Antenna Design
Random facts about antennas we found out or read about. Need to be put into an article and into context.
Why is usually a 1/2 lambda antenna used?
Imagine a Sine wave. Imagine a half wavelength starting at PI/2. It goes until 3/4 * PI. That means you have the beginning where the value of the sine is max and the end where it is minimal. That means your difference is maximized. For a wave - it's the same. Thus by using lambda / half antennas you can maximize the output-level.
To think about: Does an antenna cause a phase shift? (I think it does).
