The antenna gain equation calculates the gain of an antenna, representing its ability to focus or direct electromagnetic radiation in a particular direction
- :Â Antenna gain is a measure of the ability of an antenna to direct or concentrate the transmitted or received signal in a particular direction
- : Antenna efficiency represents the effectiveness of an antenna in converting input power into radiated power.
- : The effective area of an antenna is the hypothetical area
- : it is the distance between two successive points in a wave with the same phase
