    What do they mean by "omnidirectional" here? Like a spherical radiation pattern? Or omnidirectional in the plane that is perpendicular to a dipole antenna?

    I also agree that d is a strange answer, but knowing what they mean by omnidirectional may help...

    I should calculate the array factor correct ? And then from there I should calculate angle for maxima ?
