  • Low-profile antenna receiving vertical polarized signal
    Patent number: 8803748
    Abstract: A low-profile antenna is provided. A laminated substrate is formed into a structure in which a plurality of substrates having different permittivities are stacked, and a radiator consists of a plurality of unit patches disposed on an upper surface of the laminated substrate and generates an electric field perpendicular to the upper surface of the laminated substrate. Ground vias are formed from the respective unit patches to a ground plane disposed on a lower surface of the laminated substrate through the substrates constituting the laminated substrate. In the low-profile antenna, the radiator consisting of the plurality of patches is disposed on the upper surface of the laminated substrate having a structure in which the plurality of substrates are stacked to generate a magnetic loop around the patches, so that vertical polarized signals can be received due to a magnetic field perpendicular to the upper surface of the laminated substrate.
