摘要 |
The present invention provides a magnetic field antenna (1200) and method for utilizing a central loop (1202), carrying a current produced by a signal source or induction by an external field and a plurality of at least three non-collinear peripheral loops (1204, 1206, 1208, 1210), distributed along a perimeter of the central loop (1202), arranged for substantially cancelling a moment of the central loop (1202), and where transmitting, minimizing radiation, and where receiving, for minimizing a current induced by a substantially uniform field. |
