Linear array of monopoles. An array is made of n monopoles, all perpendicular to the ground and separated one-half wavelength from each other. The monopoles are 0.25A long and are all in phase. Calculate:
(a) The array field radiation pattern and plot it in a plane that includes the monopoles and in a plane perpendicular to the monopoles.
(b) The electric and magnetic field intensities at a general point in space for a given current. All monopoles carry identical currents.
