Abstract :
In this paper, a dual frequency reconfigurable antenna array and a discrete phase shifter are presented. The system is capable of operation at two independent frequencies (4.7 GHz and 7.5 GHz) switching between four different beam states. The reconfigurability is achieved by loading antenna and phase shifter with high frequency PIN diodes acting as microwave switches.
