Simulations of Dual and Broadband Patch Antenna
In this paper, the authors present the simulations results of the Broadband and dual band microstrip antenna. This serves to join the telecommunication services by using a single antenna. Antennas broadband and dual band were obtained by using, respectively, the technique of pile of patches and hybrid antenna. The broadband antenna is established by two patches stacked, fed by aperture coupling and the dual band antenna is a hybrid antenna consisted of an annular microstrip antenna and a wave guide. The effects of the constitutional parameters of antennas were studied.
