Optimization of a Wideband Tapped-Delay Line Array Antenna

In this paper, an optimal approach to design wideband tapped-delay line(tdl) array antenna is proposed. this approach lets us control the array angular and frequency response over a wide frequency band. to this end, some design restrictions are defined and a multi-objective optimization problem is constructed by putting the individual restrictions together. the optimal weights of the tdl processor are determined through solving this multi-objective problem. a design example is presented to show performance of the proposed method and compare the array response with those previously published in the literature.
