Abstract

A multiband antenna based on a dielectric antenna component. The antenna component (501) comprises a dielectric substrate (510) and two radiators on its surface, which radiators extend towards each other from the opposite ends of the substrate. At an end of the substrate, the first radiator (521) is connected to the antenna's feed conductor and the ground (GND). The second radiator (522) is parasitic, and it is coupled from two points to the ground at the opposite end of the substrate. These two ground couplings take place through serial resonance circuits (C51, L51; C52, L52) with different natural frequency to constitute two operating bands for the antenna. The basic component of a dualband antenna does not have to be a dualband one, in which case it can be made very small. In addition, the structural parts of said resonance circuits are very tiny. The efficiency of an antenna is good in both bands, because the volume of the whole substrate is utilized in them.
