So far, all of the arrays examined have been fed with equal currents. This id generally the case with pairs of elements, or pairs of pairs, as in the steered-cardioid array in Fig 14-11. In the case of larger arrays, the width of the array often exceeds λ/2, resulting in undesired directions at which signals from the further-apart elements add in-phase. Consider an array consisting of right vertical monopoles each separated by λ/4 with the intent of feeding them in-phase to obtain a narrow high-gain beam broadside to the array. The azimuth pattern of such a system is shown in Fig 14-12.
