Abstract:
The invention relates to an internal monopole antenna of especially a flat a radio device, which monopole antenna has an arrangement for improving its characteristics. The antenna comprises a planar monopole radiator (310) and an auxiliary element (320), which is located at the point of the planar element as viewed in the direction of its normal. The auxiliary element can be a mere conductor strip or a ceramic plate partly coated with a conductor. The conductor of the auxiliary element is connected to the ground at a point (SP), which is relatively close to the feed point (FP) of the planar element. The planar element (310) can be shaped to form two operating bands for the antenna. The auxiliary element can be used to increase the bandwidth of the internal monopole antenna and/or to improve the omnidirectional radiation of the antenna.
