Abstract: A substrate antenna (300, 700) that includes conductive shielding (712, 714) positioned adjacent to and covering at least two, preferably opposing, sides of a conductive trace (702) or antenna structure formed by the trace or traces, supported on a substrate (704). The conductive enclosure is realized by using a tubular material (1030) or planar conductive layers (1020a, 1020b) positioned adjacent to the trace. Preferably, shielding layers are disposed on at least two opposing sides of the trace. In one embodiment, a layer of dielectric material (716) is formed over the antenna trace, and one shielding layer (714) is formed on a surface of the substrate opposite that of the trace, and a second shielding layer (712) is formed on the non-conductive material, effectively sandwiching the trace and substrate between them. In further embodiments, a conductive surface (1016, 1020) is formed between and joining together the two shielding layers, along either one or two sides of the trace or substrate. One method of forming this surface is to apply a planar layer of conductive material (1020) extending between and coupled to the first and second conductive shielding layers. Alternatively, a plurality of conductive vias (1016) are formed extending through the substrate between and coupled to the first and second conductive shielding layers. A passage is provided through or around an end of the shielding enclosure near a conductive pad (710, 1010) to provide appropriate access with a signal feed for the antenna.

Abstract: A method of screening for fetal Down's syndrome is described. Screening marker levels are measured. These may be measurements of a biochemical marker in a maternal sample or measurements of a marker from an ultrasound scan. The marker levels are used to calculate a risk of Down's syndrome. Instead of using markers from a single stage of pregnancy, the method uses markers from two or li more different stages of pregnancy, typically one being in the first and another being in second trimester. The method may be automated.
