Abstract :
Two prototypes of reconfigurable antenna structure applicable to 3G communication systems are presented in this paper. The first one was designed to operate at 2.45 GHz and to steer the radiation beam from 60° to 120° with a step of 5°, by reconfiguring the feed elements. The second antenna is a V-antenna array with resonance frequency at 1.9 GHz and was constructed to full characterize the radiation pattern of this type of antenna.
