Technical terms

  • dBi
dBi

dBi (decibels relative to isotropic) is a logarithmic unit of measure that expresses the gain of an antenna compared to a theoretical isotropic antenna that radiates energy uniformly in all directions.

Imagine a light bulb that shines in all directions equally. If you put a reflector on it so the light concentrates in a single spot, that light will be much more intense there. The dBi measures how much extra "strength" the signal gains by focusing it in a specific direction instead of wasting it everywhere.

ReferenceIsotropic radiator (0 dBi)
Scale TypeLogarithmic

Directivity and Energy Focus

A higher dBi value does not mean the antenna produces more energy, but rather that it redirects existing energy more precisely, narrowing the beam angle to reach greater distances.

Advantages

  • Increased range for wireless links.
  • Reduction of side and rear interference.
  • Better signal-to-noise ratio in the main direction.

A higher dBi value indicates a more directional and longer-range signal.
