چکیده :
This paper proposes a new phase realization technique that minimizes the adverse effects of frequency dispersion in wideband reflectarray antennas by finding the optimum element arrangement on the antenna aperture. The excellence of this technique in comparison with its counterparts is to decrease the dependency of wideband reflectarray design to the element phase behavior. In order to prove the effectiveness of the presented technique, a single layer reflectarray antenna compromising of square patches loaded with split rings is fabricated and tested. Experimental results demonstrate 1.5dB gain bandwidth of about 28% covering 12-16GHz frequency band. Its Side Lobe Level (SLL) is also less than -17dB (<-13.5dB for uniform excitation arrays). Such a design technique is applicable for approximately all reflectarray elements and relieves the designer from complex multilayer structures.
