In this work, we present an elegant, simple to fabricate and very cost effective technique for designing wide-band reconfigurable reflectarray antennas. First, we utilize our recently proposed frequency pulling technique (FPT) to increase the bandwidth of reflectarray antennas (RAs). Notably, based on FPT, a simple feeding network is properly designed and connected at the backplane of each RA's unit cell. In turn, we connect readily available diodes to this feeding network properly changing its electrical characteristics and applying the desired reconfigurability. To demonstrate our technique we utilize a traditional microstrip patch element. Specifically, we (a) apply our FPT method feeding each unit cell at two properly selected feed points and achieving a 28% fractional (gain) bandwidth, and (b) use a single diode to reconfigure the RA's beams between 30O and -30° in the φ=0° plane. Our designed RA shows great beam stability for both beam states within its entire 8.85 GHz to 11.75 GHz bandwidth of operation.
