A drill string tool can be used in a drilling system, with the drill string tool configured for wireless communication. The drill string can include a central structural member, a wire coil, an antenna core, and a wear protection shell. The antenna core can surround the central structural member. The wire coil can be positioned around an outside of the antenna core, with the antenna core and the wire coil forming an antenna assembly. The antenna assembly can be configured to wirelessly transmit the data signals from electronics associated with the drill string tool. The wear protection shell can surround the antenna assembly and be configured to minimize a formation of eddy currents therein during operation of the antenna assembly. In an embodiment, the drill string tool can be a drill head wireless transmitter.

A wireless data telemetry system for use in a drilling system can include a drill head wireless transmitter and at least one data link transceiver. The drill head wireless transmitter can be in a drill head of the drilling system, the drill head wireless transmitter configured to generate and transmit one or more data signals associated with a drilling process. The at least one data link transceiver can be wirelessly coupled to at least one of the drill head wireless transmitter or another data link transceiver, with the drill head wireless transmitter and the at least one data link transceiver configured to be physically coupled within a drill string and spaced apart from one another. The drill head wireless transmitter and the at least one data link transceiver together configured to wirelessly communicate the one or more data signals beyond a transmission range of the drill head wireless transmitter.
