Abstract:
1. A downhole signal transmission system for providing communications along a drill string of downhole components comprising a plurality of interconnected downhole components, comprising: a plurality of signal repeaters spaced along said drill string of downhole components, said signal repeaters being receptive to radiofrequency signals having information modulated thereon; and at least one of said downhole components comprising: a first end containing a resonance circuit, said first end interconnecting with an end of a first adjacent downhole component, a second end, said second end interconnecting with an end of a second adjacent downhole component, and wherein said radiofrequency signals having information modulated thereon are coupled from said first adjacent downhole component to said downhole component through said resonance circuit; and are transmitted through said conductor of said downhole component to at least one of said repeaters.
