Fuzzy associative memories for the computation of the bandwidth of rectangular microstrip antennas with thin and thick substrates

A method based on fuzzy associative memories for calculating the bandwidth of electrically thin and thick rectangular microstrip patch antennas is pre sented. The design parameters of the fuzzy associative memories are optimal ly determined by using the classical, modified and improved tabu search alg orithms. The theoretical bandwidth results obtained by using the fuzzy asso ciative memories are in very good agreement with the experimental results a vailable in the literature.
