The Yagi antenna does support several radiation pattern but "Yagi" is often used in place of "Directional Yagi".

* Isotropic Antenna : radiate the same in all the direction.  

* '''Isotropic Antenna''' : radiate the same in all the direction.  

* Directional Antenna (or Beam Antenna) : radiate most of its power in one or more direction. This increase the performances in the direction while reducing the interference coming from the other directions.

* '''Directional Antenna''' (or Beam Antenna) : radiate most of its power in one or more direction. This increase the performances in the direction while reducing the interference coming from the other directions.

* Omni Directional antenna : uniformly radiates the power in one plan. With a directive pattern shape in perpendicular plane. This antenna radiates equally in all the directions and have some angle of elevation ([https://www.elprocus.com/design-of-yagi-uda-antenna/ dixit elprocus.com])

* Hemispherical antenna : radiates one half of the hemisphere (the lower or the upper one)
