Directivity of a loop antenna

A significant advantage of a loop antenna is its directional pattern, a "figure 8" shape with
two null points separated by 180 degrees. The null in reception that is located at right angles
to the plane of the loop can be used for interference reduction. On the other hand, received
signal strength is greatest in the directions indicated by the arrows.

NULL: Angle from which magnitude of the radiation pattern decreases to zero. In other words, these are the
sides from which the antenna receives the least.
Maximum reception performance is achieved when these sides of the loop face the signal.
