WebThe meaning of DIRECTIVE ANTENNA is an antenna that radiates or receives better in some directions than in others. WebMar 14, 2024 · directivity (D) is defined as: θ ϕ θ ϕ D = p n ( θ, ϕ) m a x p n ( θ, ϕ) a v g where, P n (θ,ϕ )max is maximum power density P n (θ,ϕ ) avg is average power density Pn (θ,ϕ )avg = 4 π ∬ p n ( θ, ϕ) d Ω = 4 π Ω A ∬ p n ( θ, ϕ) d Ω is beam area ( ΩA) Calculation: given: Pn (θ,ϕ )max =1 D=1 θ ϕ θ ϕ D = p n ( θ, ϕ) m a x p n ( θ, ϕ) a v g
