1. A near field communication (NFC) antenna structure comprising a first conductive body, a second conductive body, a conductive connection structure, a micro-slit structure, a first feed point, and a second feed point,
wherein the conductive connection structure bridges the first conductive body and the second conductive body,
wherein the micro-slit structure is positioned between the first conductive body and the second conductive body to separate the first conductive body from the second conductive body,
wherein the first feed point is provided on the first conductive body,
wherein the second feed point is provided on the second conductive body,
wherein the micro-slit structure includes at least one conductive layer and at least one non-conductive layer, which are separate from the first conductive body and the second conductive body and arranged alternatively along a first direction from the first conductive body to the second conductive body or along a second direction from the second conductive body to the first conductive body,
wherein the at least one conductive layer included in the micro-slit structure is connected to the conductive connection structure, and
wherein a length of the conductive connection structure is greater than a thickness of the micro-slit structure in the first direction or the second direction.
