Classification: CPC H  G | IPC G  H

Claim 0:
1. A module substrate antenna, comprising:
first and second coils connected in parallel,
wherein:
the first coil is composed of a pattern in which a spiral first antenna coil pattern and a spiral second antenna coil pattern are interlayer-connected in series,
the second coil is composed of a pattern in which a spiral third antenna coil pattern and a spiral fourth antenna coil pattern are interlayer-connected in series,
the first antenna coil pattern, the third antenna coil pattern, the second antenna coil pattern, and the fourth antenna coil pattern are located in this order, and
the first to fourth antenna coil patterns are wounded so that directions of a current flowing through the first to fourth antenna coil patterns are all the same direction with respect to an axis of the coil, are wound so that the directions of a current in the first and third antenna coil patterns are the same direction with respect to a radial direction of the coil, and are wound so that the directions of a current in the second and fourth antenna coil patterns are an opposite direction to the direction of a current in the first and third antenna coil patterns with respect to the radial direction of the coil.
