A linear antenna array comprises 5 half-wave dipoles arranged parallel to each other, lying in a plane and spaced \/2 apart. If the dipoles are fed 'in phase" (a) Write the expression for the normalised field pattern of the array (b) Plot, with aid of a computer, the field pattern in (a) (c) Calculate the angular width of the main beam at the half-power points and between the first nulls.
