摘要： An antenna apparatus includes a ground layer, patch antenna patterns, feed vias, ring-type meta patterns, and coupling-type meta patterns. The ground layer has one or more through-holes. Patch antenna patterns are each disposed above the ground layer. Feed vias are disposed to penetrate through the one or more through-holes, and electrically connect to the patch antenna patterns, respectively. Ring-type meta patterns are arranged between the patch antenna patterns. Coupling-type meta patterns are alternately arranged between the patch antenna patterns in fewer numbers than the ring-type meta patterns in positions more distant from the patch antenna patterns than positions in which the ring-type meta patterns are arranged.

摘要： An antenna apparatus includes an antenna structure and an integrated circuit (IC). The antenna structure includes a magnetic core extended in one direction, a conductive wire wound around the magnetic core to form a coil, and a magnetic material surrounding the conductive wire in a portion of the coil. The IC supplies an electrical current to the coil. In addition, a portion of magnetic flux generated by flow of the electrical current supplied to the coil exits from one end surface of the magnetic core and enters another end surface of the magnetic core opposite to the one end surface in the one direction. Another portion of the magnetic flux flows through the magnetic material surrounding the conductive wire.
