| 摘要 | A radar or other microwave antenna comprises at least one antenna element, a feed structure for the element extending to the antenna element substantially normally thereto through a dielectric substrate, and characterized in that the dielectric substrate is anisotropic whereby to reduce unwanted common-mode currents in the feed structure. The anisotropy may be provided by elongate conductive elements distributed through the dielectric substrate and aligned with their longitudinal axes parallel to the feed structure. | ||

| 主权项 | 1. An antenna for a phased array comprising at least one antenna element, a feed structure for the antenna element extending to the antenna element substantially normally thereto through a dielectric substrate, an array of discrete elongate elements distributed through the dielectric substrate, and a ground plane, each of the discrete elongate elements of the array being spaced apart from the feed structure and disposed with their longitudinal axes aligned in a first direction that is parallel to the feed structure, each of the discrete elongate elements of the array being suspended between and separated from, each of the at least one antenna element and the ground plane. | ||
