Antenna Gain: (Power Gain)


Antenna Gain: (Power Gain):

  • The gain of an antenna is specified in dBi 
  • Gain of the antenna compared to an isotropic antenna
  • An isotropic antenna is an ideal (theoretical) antenna that spreads energy in all directions (in a sphere) with equal power, which is impossible to design in practice.
  • Some antennas may have their gains expressed in dBd (though less common), (d stands for Dipole)
  • Antenna can be internal or External
