Abstract
A data transmission system for use with a drill string in a primary wellbore is disclosed. The data transmission system includes a toroidal antenna assembly. The toroidal antenna assembly is disposed around the drill string at a primary downhole location within the primary wellbore and configured to transmit a signal from a transmitter. The signal corresponds to sensor data. The toroidal antenna assembly includes a plurality of toroidal antennas, wherein each toroidal antenna is configured to transmit the same signal from the transmitter. Because a plurality of toroidal antennas are utilized to transmit the same signal, construction of the drill string can be more mechanically robust than a conventional insulated gap collar while permitting reliable and fast transmission of sensor data to the surface.
