Patent ID: 7928920

Claim:
A film antenna comprising: a base film comprising an insulating material; first and second antenna elements comprising film-like electric conductors formed on the base film; and an insulating protection sheet provided on the first and second antenna elements, wherein: each of the first and second antenna elements has one of (i) a planar shape in which two end faces from a feed point to a tip have two different lengths, or (ii) 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, the first and second antenna elements include an area as a capacitor for performing impedance matching, and the insulating protection sheet comprises a hole portion disposed at a position of the feed point for soldering connection between the first and second antenna elements and the coaxial cable.
