Abstract :
A printed planar micro-strip fed dipole antenna with reconfigurable radiation pattern properties is suggested for wireless communication. The structure consists of two resonant rings, each one is printed on one substrate layer. The dipole can switch its radiation pattern in different directions depending on the state of six PIN diode switches loaded on the resonant rings (three PIN diodes on every resonant ring). The designed antenna works at 2.4 GHz when all switches are ON and adopts a multi-frequency behavior for different states of switches. Initial results were obtained by using short and open circuits instead of implanting PIN diodes. Results at 1.54 GHz are presented and discussed. A prototype was manufactured and characterized, then measured results were compared to simulations.
