Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a small non-film type antenna, which may not be indistinctive even in a vehicle, and has wide band characteristics capable of covering frequency bands of terrestrial digital broadcasting. SOLUTION: The antenna includes a first element, a second element, and a plate. The first element includes a first feeding end, a first parallel transmission line, and a feeder. The second element includes a second feeding end, a second parallel transmission line, and a folded shape portion. The second feeding end is electrically connected to the plate set at ground potential. The first and second parallel transmission lines are mutually arranged parallel and the folded shape portion is arranged in the proximity of the plate set at ground potential to enable band-widening. Then, a meander form or a helical form is adopted for the folded shape portion. Thereby, the whole antenna can be made smaller. COPYRIGHT: (C)2011,JPO&INPIT
