METHODS AND APPARATUS FOR RADAR SIGNAL RECEPTION

摘要

An antenna is described which includes first, second, and third conductive layers (352, 354, 356) and a first and second laminate (358, 360) to separate the layers. The laminates (358, 360) are configured with plated through holes (364) to provide contact between the first and third layers (352, 356), the holes (364) defining antenna cavities, the second conductive layers (354) being the antenna. A plurality of slots (368) in the first conductive layer (352) align within the defined antenna cavities, further defining the antenna cavities for the second conductive layer (354).
