    摘要： A sensor device for detecting a change fluid level within body tissue comprising a housing with bridge segments connecting at intersections arranged to circumscribe an opening. Further, antenna elements are partially seated within the housing at intersections of bridge segments, comprise a generally planar antenna mounted to a substrate material at a base of the planar antenna, and an electrical shield surrounding the substrate. Also, an outer surface of the planar antenna faces away from the substrate. The antenna elements comprise at least first and second antenna element pairs having transmitting and receiving antenna elements and a bridging segment. A high sensitivity zone is formed between the transmitting antenna and receiving antenna. The antenna element pairs are spaced to create an area of reduced sensitivity between the high sensitivity zones, and the space is set so that the sensor is insensitive to fluid changes of a predetermined volume.
