Consider an antenna with electric field intensity in the xy-plane E(c). This electric field is generated by a current distribution D(y) in the yz- plane. The electric field intensity is computed using the integral r/2 E(C) = D(y) exp(2j sinc) dy -r/2 where is the wavelength and r is the aperture.

(a) Write an expression for E(S) when D(Y) = do (a constant).

(b) Write an expression for the normal- ized power radiation pattern and plot it in dB.
