Definition of antenna gain

WebGain + dB = dBi of an antenna. The gain can affect the direction in which the antenna operates. The higher the gain, the more directional the antenna is. The antennas power doubles for every 3dBi. This is a graphical representation of signal emitted from the antenna. In simple terms, it represents if your Antenna is directional, Bi-directional ... WebBeing a ratio, antenna efficiency is a number between 0 and 1. However, antenna efficiency is commonly quoted in terms of a percentage; for example, an efficiency of 0.5 is the same as 50%. Antenna efficiency is also frequently quoted in decibels (dB); an efficiency of 0.1 is 10% or (-10 dB), and an efficiency of 0.5 or 50% is -3 dB.
