LOOP ANTENNA

摘要

A loop antenna (206) is provided. The apparatus comprises a substrate (302), a first metallization layer (308), and a second metallization layer. The substrate has first and second feed terminals and a ground terminal. The first metallization layer is disposed over the substrate and includes a first window conductive region (408), a first conductive region (404), a second conductive region (406), and a third conductive region (402). The first conductive region (404) is disposed over and is in electrical contact with the first feed terminal (310-1); it is also is substantially circular and located within the first window region (408). The second conductive region (406) is disposed over and is in electrical contact with the second feed terminal (310-2); it is also substantially circular and is located within the first window region (408). The third conductive region (402) is disposed over and is in electrical contact with the ground terminal, and the third conductive region (402) substantially surrounds the first window region (408). The second metallization layer is disposed over and is in electrical contact with the first, second, and third conductive regions (404, 406, 402) of the first metallization layer (308), and the second metallization layer includes a second window region that is at least partially aligned with the first window region.
