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

where x is the wavelength and r is the aperture.

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

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