The invention provides a non-contact IC card read-write equipment antenna. A plurality of inner ring coils (13) disconnected with one another are disposed spirally from outside to inside from the tail end of an outer ring coils (11). A disconnecting position of every two inner ring coils (13) has two opposite disconnecting points (131). The corresponding inner ring coils (13) and the outer ring coils (11) are connected by short-circuiting the corresponding disconnecting points (131) to change to the number of coils of the non-contact IC card read-write equipment antenna. The number of coils of the antenna can be flexibly, conveniently and quickly adjusted to adapt to the varying product demand and using environments, the redesign of the antenna is not required, and the time for developing the antenna is saved.
