1. A sheet member for improving communication used when performing wireless communication using an antenna element in a vicinity of a communication jamming member having a portion made of a conductive material, the sheet member being disposed between the antenna element and the communication jamming member, and comprising:

  • a pattern layer in which a conductive pattern portion is formed, the conductive pattern portion resonating with an electromagnetic wave used for wireless communication, storing electromagnetic energy, forming electromagnetic coupling with the antenna element, and transferring the stored electromagnetic energy to the antenna element; and

    a storage layer that is interposed between the pattern layer and the communication jamming member, that is made of a non-conductive dielectric layer and/or magnetic layer and that collects energy of electromagnetic waves used for wireless communication to pass therethrough, thereby improving a communication distance by wireless communication.
