Abstract

The bandwidth behavior of reflectarray elements are discussed in this paper to overcome the intrinsic limitation of narrow bandwidth it offers. This is done by analyzing the relationship between bandwidth and phasing distribution characteristics of the elements. Five shapes of elements, i.e., ring, rectangular loop, triangular loop, square loop and ellipse loop have been investigated. Each element is designed on Kapton sheet positioned on top of a coverglass layer that protects the silicon layer. Rogers RT/Duroid 5880 dielectric substrate (εr = 2:2 and tan δ = 0:0009) is used to support the layers above. These elements are designed to operate at Ku-band frequency range using CST microwave studio. The elements dimension are varied thus modfies the surface current distribution that leads to variation of phase reflection from the elements. The relationship of bandwidth performance with the obtained reflection loss of each element is then investigated. It has been demonstrated from this work that triangular element can offer the highest static linear phase range about 263°, whereas the square element gives the lowest static linear phase range of 153°. The surface area of resonating element has significantly control the current distribution hence leads the triangular element with the lowest surface area to has steep phase variation. While square element with greater surface area is shown to exhibit smoother phase variation with broader bandwidth performance. Moreover, the CST simulation results also shown that triangular element can operate at two resonant frequencies within Ku- band at 12.22 GHz and 14.09 GHz which can be further exploited for satellite and communication applications.
