The through-hole array chip can be formed by a conventional semiconductor manufacturing ... Directivity is an important measure because many antennas and optical systems are designed to radiate electromagnetic waves in a single direction or over a narrow-angle. By the principle of reciprocity, the directivity of an antenna when receiving is equal to its directivity when transmitting. See more In electromagnetics, directivity is a parameter of an antenna or optical system which measures the degree to which the radiation emitted is concentrated in a single direction. It is the ratio of the radiation intensity in … See more In an antenna array the directivity is a complicated calculation in the general case. For a linear array the directivity will always be less than … See more The directivity is rarely expressed as the unitless number $${\displaystyle D}$$ but rather as a decibel comparison to a reference antenna: $${\displaystyle D_{\text{dB}}=10\log _{10}\left[{\frac {D}{D_{\text{reference}}}}\right].}$$ The reference antenna is usually the theoretical perfect See more The term directivity is also used with other systems.
