What is meant by antenna gain?

Antenna gain is the ability of the antenna to radiate more or less in any direction compared to a theoretical antenna. If an antenna could be made as a perfect sphere, it would radiate equally in all directions.

What is antenna gain formula?

Antenna Gain Formula:

G d b i =10 L o g 10(η*4π* A )λ 2.

What is antenna gain and efficiency?

Antenna Gain is the ratio of power transmitted in a certain direction with a specific reference point. Relation between gain and efficiency is G = e x D where D is the directivity and E if the efficiency Antenna efficiency is how much RF power delivered to the antenna (from radio) is actually transmitted into the air.

What is the best gain for antenna?

On an open and flat highway, a high gain antenna will be better… 3 dB, 6 dB, etc. If your desired coverage area is hilly then a ¼ wave omnidirectional antenna will be better. The other type of gain is directional and is important for base stations.
