  • Publication number: 20210313691
    Abstract: A display device includes a display panel in which an active area and a peripheral area are defined, and an antenna unit including a main pattern, a first sub-pattern, and an antenna line. The main pattern is disposed on the display panel in the active area, transmits and/or receives a signal, and operates at a first frequency. The first sub-pattern is disposed on the display panel in the active area, is spaced apart from the main pattern in a first direction, is capacitively coupled to the main pattern, and operates at a second frequency different from the first frequency.

  • Patent number: 9819089
    Abstract: A circularly polarized Global Positioning System (GPS) antenna using parasitic lines, in which circular polarization is implemented to improve the efficiency of the reception of satellite signals by an antenna. For this, a circularly polarized GPS antenna using parasitic lines according to an embodiment includes a substrate, a radiating patch formed on a top of the substrate, a parasitic line part formed on the top of the substrate and disposed to be spaced apart from the radiating patch, thus implementing circular polarization characteristics by inducing reverse current, a ground plate formed on a bottom of the substrate, and a feeding via formed through the substrate and configured to electrically connect the ground plate to the radiating patch.
