AV - public UR - http://www.eledia.org/students-reports/436/ Y1 - 2011/01// TI - Hybrid design of a fractal-shaped GSM/UMTS antenna N2 - In this paper, the synthesis of a three-band planar antenna working in the GSM (900 and 1800 MHz) and UMTS frequency bands is presented. As reference geometry, a hybrid pre-fractal shape has been adopted by integrating a sierpinski-like and a Meander-like structure. The synthesis of the antenna has been performed by optimizing the descriptive geometrical parameters of the reference shape by means of a customized Particle Swarm strategy to comply with the electrical and geometrical requirements.
