Abstract: Security paper based on an RF tag using a dipole array structure and a method for manufacturing the security paper. The security paper based on an RF tag using a dipole array structure includes first base paper, second base paper, and an RF tag printed on at least one of the first base paper and the second base paper, wherein the RF tag is configured such that multiple dipole antennas form an array structure. Also, the security paper based on an RF tag using a dipole array structure may include a layer configured with a pattern or a color or a carbon-coated layer, whereby the location of the RE tag is prevented from being exposed and whether the corresponding paper is security paper may be detected.

Abstract: An ultra-wideband (UWB) antenna having a frequency band notch function is provided. The UWB antenna includes a substrate, a radiation part, a feeding part, and a slot. The radiation part is formed on one surface of the substrate, and radiates radio signals. The feeding part is formed on the other surface of the substrate, and feeds electric signals to the radiation part. The slot is formed in a stub formed at one end of the feeding part, and rejects frequencies in a notch band in the radio signals that are radiated by the radiation part.

Abstract: Disclosed herein is a method for constructing a joint between thin flexible sheets of electromagnetic shielding material. The method includes adhering first sides of multiple first sheets of shielding material to a wall and adhering first sides of multiple second sheets of shielding material to second sides of the multiple first sheets of shielding material. A conductive adhesive or a conductive double-sided adhesive tape may be applied to the first side of each of the first sheets of shielding material and the second sheets of shielding material, the first sheets of shielding material may be arranged to abut each other along at least one first seam, and the second sheets of shielding material may be arranged to abut each other along at least one second seam.
