ABSTRACT:
In a helical antenna to be installed inside a mobile communication terminal, for processing low-bandwidth signals, a substrate is made of magnetic dielectric material, a plurality of lower electrodes are disposed on the underside of the substrate, and a plurality of upper electrodes are disposed on the top of the substrate. The upper electrodes are inclined with respect to the lower electrodes, respectively, at a predetermined angle. A plurality of side electrodes electrically connect the lower electrodes with the upper electrodes, respectively. At least a part of a magnetic moment vector, which is formed around each of the lower electrodes by a current flowing in the each lower electrode, is directed in parallel with a current flowing in each of the upper electrodes corresponding to the each lower electrode.
