(Q). Determine the gain, beamwidth, and capture area for a parabolic antenna with 10m diameter dish and dipole feed at 10GHz

f = 10GHz

λ = 3*10^8/(10*10^9) =0.03

and D = 10 m

so, BWFN = 140 λ /D

= 140*0.03/10

BWFN = 0.42^O

G_P = 6*(D/ λ)^2

G_P = 6*(10/0.03)^2

G_P = 666666

and

Capture Area(A) = λ^2*G/4π

Capture Area(A) 47.74 m²
