Abstract

There has been much interest recently in developing reflectarray antennas due to the combination of some of the best features between the parabolic reflector and phased array antennas. This paper presents the study of the relationship between phasing distribution characteristics and the bandwidth of different resonant reflectarray elements. The gradient characteristics of different elements of patch, dipole and ring, printed on a grounded dielectric substrate have been investigated at X-band frequency range using the commercial CST computer model. The preliminary simulated results demonstrate that ring elements contribute the highest reflection loss performance of about -1.737 dB compared to the other two elements of dipoles and patches. The attainable static linear phase range of 177 for ring elements is shown to offer a trade-off between the static phase range and the bandwidth of the reflectarray elements.
