摘要

The scan range of an antenna array can be increased by providing a degree of curvature to its structure. However, achieving a wide scan range with an antenna array with limited number of elements is a challenging design issue. In this study, a novel 8-element linear array of polarisation reconfigurable antennas conformed to four different array structures; namely 2-faceted, 3-faceted, 4-faceted and 8-faceted are analysed and synthesised. Observations are made on the influence of the tilting angle of the faceted structures to the geometrical characteristics and the scan range of the array. It is shown that the 3-faceted array can achieve the widest scan range with the smallest dimension compared with the other faceted structures. Furthermore, the results show that the 3-faceted structure achieves +69u000b0; scan range, compared to +56u000b0; achieved with a linear array.
