Abstract :
This work studies the design of broadband Yagi-Uda antennas considering 3 conflicting specifications in 3 different frequencies, thus, a 9 objectives optimization problem. This multiobjective problem was solved using the cone of efficient direction algorithm and the multiobjective line search. Results for 6 elements antennas are presented
