ABSTRACT:
A film antenna comprises a base film formed of an insulating material; and first and second antenna elements of film-like electric conductors formed on the base film, wherein each of the first and second antenna elements is a planar shape in which two end faces from a feed point to a tip have two different lengths or a planar shape in which an end face and a diagonal line from a feed point to a tip have two different lengths, a core wire of a coaxial cable is connected to the first antenna element at the feed point, an external conductor of the coaxial cable is connected to the second antenna element at the feed point, and the first and second antenna elements have an area as a capacitor for performing impedance matching.
