Iām a geek brother. I remembered a Navy class and many instruction modules on antennae and waveform propagation. So I did a search and made one. Used this concept because it uses the same concept as the commercial ones that mount inside your home. Fractal antennae are why you donāt have an external antenna on your cell phone.
