  • ANTENNA DEVICE
    Publication number: 20240195070
    Abstract: An antenna device includes an antenna unit including a radiator, a dummy mesh pattern disposed around the radiator and spaced apart from the radiator, the dummy mesh pattern including comprising dummy conductive lines and segmented regions where the dummy conductive lines are cut, and a parasitic element disposed between the radiator and the dummy mesh pattern to be spaced apart from each of the radiator and the dummy mesh pattern, the parasitic element having a mesh structure.

  • Nanocomposite nanostructure-based surface-enhanced Raman scattering respiratory droplet mask sensor and fabrication method therefor
    Patent number: 11921048
    Abstract: The present disclosure relates to a fine particle-trapping sensor including: a plasmonic hotspot layer formed of a first metal; and a trapping layer formed of a second material. The inventors of the present disclosure have made extensive research efforts to develop a more effective and novel sensor for the real-time and high-sensitivity detection of droplets emitted from the oral cavity. As a result, the inventors have developed an alloy composite nanostructure including a Raman sensor layer, formed of a metal, and a trapping layer formed of a dielectric material, and have found that, when the ratio between the two layers is adjusted, the alloy composite nanostructure effectively traps respiratory droplets rapidly emitted from the oral cavity and detects coronavirus (SARS-CoV-2 lysate) in the respiratory droplets at a concentration of 10 pfu/ml, indicating that the composite nanostructure may be very advantageously used in the field of fine particle trapping.
