Answer:
The gain of each antenna in decibels is 353 .33 dB.
Step-by-step explanation:
Given:
Frequency = 2 GHz
Diameter = 1.2 m
To Find:
The gain of each antenna in decibels = ?
Solution:
Relationship between antenna gain and effective area
-----------------------------------(1)
Where
f is frequency
is effective area
c is the speed of light
= effective area of a parabolic antenna with a face area of A is 0.56A

r is the radius
r =

r = 0.6



Substituting the values in eq(1)



=

= 353 .33 dB
