  • Artificial magnetic conductor
    Patent number: 9093753
    Abstract: An artificial magnetic conductor includes a conductor layer, a ground layer, and a via. The conductor layer is formed in a first direction and includes a plurality of grid cells. The ground layer is formed in a second direction that is opposite to the first direction and generates a lower frequency than that of an artificial magnetic conductor including a plurality of grid cells having the same size as that of the plurality of grid cells of the conductor layer and a conductor plate having a form that is not modified. The via is formed between the conductor layer and the ground layer to electrically connect the conductor layer and the ground layer.
