Question
Q] The E-field pattern of an antenna, varies as follows: E(0,0) = 10 cos? (0) sin(4) V/m for 0 <0<n/2 and 0<os 2n, %3D and it is zero elsewhere. a- What is the directivity of this antenna? b- What is the radiation resistance of the antenna if the terminal current is 5 A (rms)? c- Determine the gain if the antenna is assumed to have loss resistance of 12.
