Abstract
An attachable booster antenna attachable to a coil antenna, includes a body; and an antenna including a multiple resonant antennas arrayed on the body, with each resonant antenna including an insulator layer having first and second surfaces; and first and second loop antennas disposed on the first and second surfaces, respectively, so as to confront each other via the insulator layer. Moreover, the first and second loop antennas each having an opening that discontinue a part of a loop and are arranged such that a closed loop is defined by at least a part of the first loop antenna and at least a part of the second loop antenna in a transparent plane viewed from a normal direction of the insulator layer. Furthermore, in the plan view of the insulator layer, the opening of the first and second loop antennas and the opening of the coil antenna overlap each other.
