In this paper, we introduce an advanced design of a horizontally steerable planar antenna array, specifically engineered for sophisticated radar applications. The design features a comprehensive 60° steering sector alongside a notable 12% bandwidth, achieved through an innovative configuration of eight identical elements. Each element consists of a 3-element series-fed vertical array, utilizing aperture feeds with meticulously dimensioned patches to optimize performance. This paper explores the detailed process of designing and refining this array, focusing on its exceptional horizontal steering capabilities and bandwidth efficiency. By employing series-fed vertical arrays with variable patch dimensions, we have successfully developed an antenna array that meets the stringent bandwidth requirements essential for radar technology, thereby enhancing the operational versatility of radar systems.
