The invention relates to a dielectric antenna, particularly suited to portable
radio devices. The feed conductor (231) of the antenna is shaped so that
it at the same time in itself serves as a radiator in the same frequency range
as the dielectric resonator (220) of the antenna. The resonance frequencies
of the feed conductor and the dielectric resonator are advantageously arranged
to be so near to each other that there is formed a united operation band. The feed
conductor is advantageously located on a surface (223) of the dielectric
element. The structure may also include parasitic conductors. For the antenna according
to the invention, there is obtained a larger bandwidth than for corresponding antennas
of the prior art. Moreover, the air gaps between the feed conductor and the dielectric
element are avoided, as well as resulting changes in the electric properties.
