Calculating Gain of Patch Antennas
Gain measures the effectivity and directivity of an antenna, indicating how well it focuses energy in a specific ar direction. It is calculated by combinining the directivity with the antenna 's effectivency.

Directivity can be derived from the radiation sampon, while e efficiency accounts for losses in the antenna materials and design. Typical gain valies for patch antennas range from6 to 9 dBi, deposing on design parameters.
