The present invention concerns application of a unique conductive electrode geometry used to form an efficient wideband one- or two-way wireless data , link between autonomous systems separated by some distance along a bore hole drill string. One objective is the establishment of an efficient high , bandwidth communication link between such separated systems using a unique , electrode configuration that also aids in maintaining a physically robust drill string. Insulated or floating electrodes of various selected geometries provide a means for, sustaining or maintaining a modulated electric potential adapted for injecting modulated electrical current into the surrounding subsurface …
