摘要： A magnetodielectric substrate includes a first dielectric layer, a second dielectric layer, conductive patterns, and a plurality of air vias. The first dielectric layer has a predetermined height, and the second dielectric layer is stacked on the first dielectric layer. Conductive patterns are coated on an upper surface and a lower surface of one of the first and second dielectric layers. A plurality of air vias is formed with a predetermined diameter and a predetermined interval such that they pass through up to the conductive patterns of the upper and lower surfaces from the dielectric layer on which the conductive patterns are coated.

摘要： A Global Positioning System (GPS) signal reception apparatus including a GPS antenna unit, a GPS signal selection unit, and a jamming signal detection unit is provided. The GPS antenna unit includes a first-type antenna and a plurality of second-type antennas which have directivities different from each other. The GPS signal selection unit selects any one of the first-type antenna and the plurality of second-type antennas as a selected antenna. The jamming signal detection unit detects a jamming signal present in a GPS signal by analyzing the GPS signal which is received via the selected antenna.
