Sažetak
In antenna array design, linear arrays forming pencil beams are usually considered. For their design, various optimization and analytical methods have been developed. Despite many efficient optimization techniques, the analytical methods are preferable since they ensure fast and robust design. The simplest analytical method is based on polynomial approximation. In this paper, we propose a class of symmetrical linear arrays that approximate the pencil beam by using the Pascal polynomials. The proposed arrays bring very low far-out sidelobes even for a small number of elements. On the other hand, such sidelobes increase dynamic range ratio with an increase in the array size. However, for a small number of elements, the ratio is reasonably low. Furthermore, the proposed arrays exhibit higher beam efficiency than do many known low-sidelobe arrays. Such behavior is paid by somewhat wider beamwidth and slightly lower directivity.
