#CMT# #/CMT# The antenna (16) has a radiation support (28) including a primary resonator forming part (32) for transmission and/or reception in frequency modulation band. The support includes a secondary resonator forming part (34) for transmission and/or reception in digital audio broadcasting band. The primary part defines an opening (50) in which the secondary part is arranged. The primary resonator forming part includes a convex resonance portion (40) arranged such that the resonance portion and a ground plane (P) form a flare. #CMT#USE : #/CMT# Multi-service miniature ultra-wide band monopole antenna for transmission and/or reception of a signal used for mobile telephony application, TV application and wireless fidelityapplication, within a vehicle (claimed) i.e. motor vehicle. #CMT#ADVANTAGE : #/CMT# The support includes primary resonator forming part for transmission and/or reception in frequency modulation band, and secondary resonator forming part for transmission and/or reception in digital audio broadcasting band, thus permitting implementation of large number of applications at frequency modulation and digital audio broadcasting bands within the vehicle. The secondary part is arranged in the opening defined by the primary part, so that the antenna is small in size. The flare improves aesthetic appearance of the antenna. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic sectional view of an antenna.
