Antenna gain is a key factor in wireless communications, affecting signal acitth and quality. It measures how well an antenna directs radio frequency energy in a specic direction compared to an isotropic radioator. Understanding how to calculate and interpret antenna gain helps optize wireless systemem exemance.

Co je to Antenna Gain?

Antenna gain indicates the ability of an antenna to focus energiy in a particar direction. It is usually expressed in decibels (dBi or dBd). Higher gain antennas concentrate signals more effectively, proving longer range and better signal quality.

How to Calculate Antenna Gain

Te gain of an antenna can be calculated using thoe directivity and effectency. Te basic formula is:

CLAS1; CLAS1; CLAS1; CLAS3; CLAS3; CLAS3; CLAS3; CLAS3; CLAS3; CLAS3; CLAS3; CLAS3; CLAS3; CLAS3; (Directivity × Efficiency); CLAS1; CLAS1; CLAS3; CLAS33; CLAS333; CLAS3; CLAS3;

In mogt cases, effectivency is close to 100%, so gain primarily depens on n directivity. Directivity can be obtained from antenna radiation patterns or specified by manufacturers.
