1. An apparatus for sensing signals on conductors comprising:

  • a ceramic sensor body;

    a plurality of antenna elements formed in the ceramic sensor body, wherein each antenna element includes a conductor sensing end and is positioned to each other to form an antenna array having a substantially planar sensor face that is to be placed adjacent to the conductors to be sensed, each of said antenna elements further comprising,a central electrode, anda surrounding shield electrode spaced from the central electrode; and

    signal processing means connected to each antenna element for receiving the signal output from each antenna element and processing the received signals for determining the presence of signals passing through the conductors.
