Bakeng sa tekanyo e sebetsang ea coefficient ea antenna directivity, re e hlalosa ho tloha ho boholo ba mahlaseli a mahlaseli a antenna.
Directivity D ke karo-karolelano ea boholo ba matla a mahlaseli a mahlaseli a P(θ,φ) Max ho boleng ba eona bo bolelang P(θ,φ)av sebakeng sa sebaka se hōle, 'me ke tekanyo e se nang dimension e kholo ho feta kapa e lekanang le 1. Foromo ea lipalo e tjena:
Ntle le moo, directivity D e ka baloa ka foromo e latelang:
