Claim 2:
3. The module substrate antenna of claim 1, further comprising:
a third coil connected in parallel with the first and second coils,
wherein:
the third coil is composed of a pattern in which a spiral fifth antenna coil pattern and a spiral sixth antenna coil pattern are interlayer-connected in series,
the first antenna coil pattern, the third antenna coil pattern, the fifth antenna coil pattern, the second antenna coil pattern, the fourth antenna coil pattern, and the sixth antenna coil pattern are located in this order, and
the first to sixth antenna coil patterns are wound so that directions of a current flowing through the first to sixth antenna coil patterns are all the same direction with respect to the axis of the coil, are wound so that the directions of a current in the first, third, and fifth antenna coil patterns are the same direction with respect to the radial direction of the coil, and are wound so that the directions of a current in the second, fourth, and sixth antenna coil patterns are an opposite direction to the direction of a current in the first, third, and fifth antenna coil patterns with respect to the radial direction of the coil.
