%X This paper describes the design process of an integrated antenna for an automotive rescue system. In order to fulfill the antenna design requirements in different frequency bands and to minimize the interference phenomena arising from the integration of different classes of antennas in a single device, a two-phases stochastic optimization approach is used. The experimental validation carried out on the developed prototype confirms the effectiveness of the proposed approach. %D 2005 %I University of Trento %A Renzo Azaro %A Giulia Boato %A Francesco De Natale %A Gabriele Franceschini %A Anna Martini %A Andrea Massa %L elediasc12346 %T Design of an Integrated Antenna for Automotive Systems
