👉 Directivity is a concept in electrical engineering that refers to how much of a signal or wave can be received by an antenna. It is also known as "attenuation," which means it reduces the amount of energy or power being transmitted through a medium (such as air, water, or metal). Directivity is typically measured in decibels (dB) and is used to quantify how much of a signal is lost compared to what would be received with perfect reflection.
