Multi-service miniature ultra-wide band monopole antenna for motor vehicle, has primary and secondary resonator forming parts for transmission and/or reception in frequency modulation band and digital audio broadcasting band, respectively

摘要

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.
