Abstract

The invention relates to an antenna structure for a motion metal detector, comprising an antenna body, at least one receiving coil, and one transmitting coil. One of the main objectives of this invention is to provide an antenna structure capable of maintaining a stable induction balance while being less sensitive to shocks inherent in its field use. To this end, the inventor proposes an innovative configuration of the coils, which are arranged with respect to a reference plane so as to capture or transmit signals of opposite directions in a central portion 113. In particular, the arrangement of the central portion of the antenna structure is designed so that, in response to a shock, the signals captured or transmitted in the central portion 113 tend to cancel each other out, while maintaining the induction balance.
