Abstract:
A sheet antenna comprising:a sheet of electrically-insulting material;antenna feed means comprising an electric source, a first feed element connected to said electric source, and second feed element connected to said electric source;a first pair of electrically conducting lands comprising a first land and a second land, said first land and said second land being disposed on said sheet, wherein said first land is electrically connected to said first feed element and said second land is electrically connected to said second feed element and said first land and said second land are positioned symmetric about and spaced apart from an imaginary line on said sheet; anda second pair of electrically conducting lands, comprising a third land and a fourth land, said third land and said fourth land being disposed on said sheet, wherein said second pair of lands is spaced-apart from said first pair of lands along the imaginary line, electrically-insulated from said first pair of lands, and wherein said third land and said fourth land are symmetric about the imaginary linewherein each land in said first and said second pair of lands is substantially two-dimensional with an x-axis parallel to the imaginary line and a y-axis orthogonal thereto, the maximum x-axis dimension being about the same as the maximum y-axis dimension for each said land.
