PROBLEM TO BE SOLVED: To provide a helical antenna installed inside a mobile communication terminal and processing low-bandwidth signals. SOLUTION: The rectangular helical antenna according to the present invention includes: a substrate made of magnetic dielectric material; a plurality of lower electrodes disposed on the underside of the substrate; a plurality of upper electrodes disposed on the top of the substrate and inclined at a prescribed angle with respect to the lower electrodes, respectively; and a plurality of side electrodes for electrically connecting the plurality of lower electrodes with the plurality of upper electrodes, respectively. At least a part of magnetic vector moment, which is formed around each of the lower electrodes by current flowing along the each lower electrode, is directed in parallel with current flowing along each of the upper electrodes corresponding to the each lower electrode.
