    摘要: A multi-field antenna (300) is configured to be able to receive a signal over one of a plurality of different fields in response to a switch. The multi-field antenna (300) comprises a mobile computer interface (316), first (302) and second (304) magnetic loops, and a first metallic element (308). The mobile computer interface (316) interfaces the multi-field antenna (300) with a mobile computer for receiving and processing the signal. The first magnetic loop (302) is tuned by a first tuner (312) to provide a first field for reading data. The second magnetic loop (304) is tuned by a second tuner (314) to provide a second field for reading data. The second field is narrower than the first field. The first metallic element (308) covers at least a portion of the second magnetic loop (304) and comprises a slot (320) extending along its length from one end of the first metallic element (308) to a point proximal an opposite end of the first metallic element (308).
