Abstract :
It is shown that the problems of antenna pattern synthesis and digital filter design are similar in nature. With this in mind, some recent techniques common to digital filter design are examined in terms of their applicability to antenna pattern synthesis. An equiripple formulation of the weighted-least-squares method is developed to show how it can be used for both sector and pencil beam patterns. Several design examples are presented
