Antenna gain is a key factor in wireless communions, affecting signal contricth and quality. It measures how well an antenta directs radio frequency energy in a specific direction commared to o an isotropic radiator. Understanding how to calculate and interpret antenna gain helps optimize wiess system performance.

Co z Antenną Gain?

Antenna gain indicates the ability of an antenna to focus energy in a particar direction. It is usually expressed in decibels (dBi or dBd). Higher gain antens contribute signates more effectively, provising longer range andd better signal quality.

How tu Calculate Antenna Gain

Te gain of an antenna can be calculated using thee directivity and efficiency. Te podstawowe formuły is:

(Directivity × Efficiency)

Nie most cases, wydajność is close to 100%, so gain primarily depends on directivity. Directivy can be avained frem antenna radiation Patterns or specified by equirers.
