PROBLEM TO BE SOLVED: To provide a DAB(digital audio broadcasting) film antenna which has a simple structure, is small-sized and light in weight, is capable of being manufactured at a low cost, is not limited by an installation place, is simple to be installed, expands a frequency band with a simple means and secures required directivity. SOLUTION: This DAB film antenna is provided with a compound antenna element 2 consisting of a resin film 1 and a strip-shaped thin film conductor and feeding cables 4 and 5 connected to a power feeding part 3 of the element 2. The element 2 consists of a 1st antenna element 21 adapted for a 1st frequency band f1 and a 2nd antenna element 22 which is provided side by side with it and is adapted for 2nd frequency band f2 being lower than the band if, and the element 22 is bent and formed at a zero level point part of a current distribution based on the electromagnetic waves of the band f1 which occur on the element 22. |
