摘要：PROBLEM TO BE SOLVED: To provide a sheet antenna that comprises an antenna sheet on which an antenna pattern is printed and that can be used at a practical level in such a way that the sheet antenna is adhered to a window of an automobile with a sufficiently high gain. SOLUTION: An antenna pattern formed on a sheet 31 comprises: a radiation element part 32 formed by arranging a plurality of radiation elements 32a, 32a in series via an inverse phase component part 32b and integrally forming them; and a matching part 33 for enclosing the end of the radiation element part 32 acting as a feeding point 32d as a center nearly in a U shape and having a pair of ground parts 33b, 33c extended in a direction orthogonal to the axial direction of the radiation element part 32.
