A wideband millimeter-wave reflectarray antenna is investigated. First, using the microstrip technique, a new dual-resonance unit cell is proposed for the reflectarray, which provides an approximately linear phase response of $0^{\circ }\text{--}360^{\circ }$ range. Additionally, its phase response curves are nearly parallel within a broad band, which can widen the operating bandwidth of the reflectarray...
A wideband single-layer microstrip reflectarray is investigated. Firstly, a new dual-resonance unit cell is proposed for the single-layer reflectarray, which provides an approximately linear phase response during 0-360° range. Additionally, its phase response curves are nearly parallel within a broad band, which can widen the bandwidth. Then, a 576-element reflectarray of size 12λ×12λ using the proposed...
In this paper, a novel resource allocation algorithm (CPFAH) for future wideband mobile communication systems is proposed. The basic idea is to schedule mobile stations according to their respective retransmission times. Thus the retransmission delay can be reduced and user fairness can be maintained. The algorithm takes the advantage of conventional performance-enhancing methods, e.g. frequency hopping,...
