Abstract
An extended dipole antenna for an uplink transmitter positioned in a wellbore includes an electromagnetic telemetry system interface sub, wired or lined drill pipe segment, and upper dipole terminating sub. The electromagnetic telemetry interface sub includes an outer tubular in electrical contact with a negative output of the uplink transmitter and an inner conductor in electric contact with a positive output of the uplink transmitter. The wired or lined drill pipe segment includes an outer tubular in electrical contact with the outer tubular of the electromagnetic telemetry interface sub and an inner conductor in electric contact with the inner conductor of the electromagnetic telemetry system interface sub. The upper dipole terminating sub including an outer tubular at least partially in electric contact with the outer tubular of the wired or lined drill pipe segment and an inner conductor in electric contact with the inner conductor of the wired or lined drill pipe segment. The upper dipole terminating sub includes an electrical connection between the inner conductor of the upper dipole terminating sub and the inner conductor of the upper dipole terminating sub.
