Abstract:
1. A coupled-loop chip antenna comprising: a microwave substrate shaped as a hexahedron; a first conductive layer, disposed on an upper surface of the substrate, adapted to form a first loop; a second conductive layer, disposed on a first side surface of the substrate, and electrically coupled to a feed-in point and a ground point; and a third conductive layer, disposed on a lower surface of the substrate, adapted to form a second loop, wherein the first conductive layer and the second conductive layer are electrically coupled at a first junction between the upper surface and the first side surface, and the second conductive layer and the third conductive layer are electrically coupled at a second junction between the first side surface and the lower surface; and wherein the third conductive layer includes a bent conductive layer and a rectangular conductive layer, and wherein the first conductive layer partially overlaps the rectangular conductive layer and does not overlap the bent conductive layer in a vertical direction perpendicular to the upper surface of the substrate.
