  • Patent number: 11005166
    Abstract: Disclosed is a patch antenna module, which receives a signal for position information and a signal for vehicle communication by using one patch antenna, thereby minimizing a mounting space. The disclosed patch antenna module includes a dielectric; an upper patch formed on one surface of the dielectric and for receiving a signal for position information; a lower patch formed on the other surface of the dielectric; and a feed pin for penetrating the dielectric, the upper patch, and the lower patch, formed in a length within a predetermined range, and for receiving a signal for vehicle communication.

  • Patent number: 10923823
    Abstract: Disclosed is a patch antenna, which is formed so that the upper surface of a dielectric layer has a wider area than the lower surface thereof and is mounted on a printed circuit board to form an air gap, thus maximizing antenna performance while implementing lightweight. The disclosed patch antenna includes a dielectric layer, a radiation patch formed on the upper surface of the dielectric layer, and a lower patch formed on the lower surface of the dielectric layer; and the dielectric layer is formed so that an area of the upper surface is wider than an area of the lower surface to form an air gap between the printed circuit board and the dielectric layer.

  • Patent number: 10439266
    Abstract: Disclosed is a wideband patch antenna module where two feeding points are formed on a lower patch at a preset angle therebetween, whereby ultra-wideband characteristics receiving both a GPS signal and a GLONASS signal may be realized, and antenna size and manufacturing costs may be minimized. The wideband patch antenna module includes a base layer; a radiation patch provided on a top surface of the base layer; a lower patch provided at a bottom surface of the base layer; a first feeding point provided at a bottom surface of the lower patch; and a second feeding point provided at the bottom surface of the lower patch, wherein an imaginary line connecting the first feeding point and a center point of the lower patch intersects with an imaginary line connecting the second feeding point and the center point of the lower patch.
