Directional Antennas
An antenna is known as "directional" if its pattern strongly favors a certain direction. A directional works by concentrating the signal in one direction at the expense of other directions. It is also commonly referred to as the "Beam" antenna. I am going to start with the earliest type of beam discovered, the "Yagi" Beam. This type of beam was discover by Professor Uda but the english translation was done by Hidetsuga Yagi. This design goes back to the 1920s! One would think today there would be better designs. I believe there is, and that's why I am so interested in antennas!
Don't mention it.
