Abstract
A protective shield for an electrically steered, high performance C Band antenna array is disclosed. The shield is of a multi-layer construction in which a sandwich is formed between two fiberglass layers and a central foam core to minimize electrical reflections; and in which an additional foam layer is provided for structural support and to minimize changes in mutual coupling, installed between the sandwich and planarly disposed dipoles of the array. In addition, a teflon layer is applied to the outer layer of the sandwich and coated with fumed SiO.sub.2. The hydrophobic properties of the teflon-fumed SiO.sub.2 combination minimizes the effects of rain on antenna performance.
