Module substrate antenna and module substrate using same

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.
