(electromagnetism)
A measure of the effectiveness of a directional antenna as compared to a standard nondirectional antenna. Also known as gain.

Antenna Gain

 

a dimensionless quantity that is equal to the product of the directivity and the radiation efficiency of a transmitting or receiving antenna (see). [27–286–1 ]

Kinematics, link budget, and antenna gains are well investigated and understood in aeronautical [12], communications [14], and antenna engineering [8] domains separately; however, to the best of our knowledge a study of linkbudget emphasizing the effect of kinematics has not been done; that is, the link budget calculations generally assume static antenna gain [15].

In addition, the transmitters maintain nearly their original level of performance, especially in terms of the antenna gain and radiation pattern, as the proposed antenna mainly receives the dissipated power which does not contribute to the performance of the radiator.
