How the reflection in Reflector of Yagi Uda antenna takes place??
The Yagi-Uda Antenna consists of a minimum of 3 elements, though 6 elements tend to be an optimum configuration.
One of the elements is called the "driven" element. One of the elements is called the "reflector" and the rest are called the "directors".
The reason why the reflector is such is wrapped up in transmission line theory. In a nutshell, the reflector is slightly longer than lambda/2 and it acts as an inductor and thereby acts as a reflector.
The directors are slightly shorter than lambda/2, acting as a capacitor and hence directs the wave.
