FIELD: antenna equipment.
SUBSTANCE: invention relates to the field of antenna technology, namely to compact resonant antennas. Resonant spiral antenna consists of a primary coil and a secondary coil. Primary coil is a frame connected to the power point. Secondary coil is a flat helix wound by a conductor in N layers and M turns. Primary coil and secondary coil are interconnected by an inductive coupling.
EFFECT: technical result consists in reducing the overall dimensions, increasing the maximum input signal power and improving the efficiency of small antennas.
