A ground penetration radar (GPR) antenna system is integrated into a digging machine such that the system is configured to remain operable under the same environmental conditions as the machine. The system includes a GPR antenna and an inertial measurement unit (IMU). The GPR antenna includes a rectangular hollow enclosure made of a conductive material defining a cavity therein and is affixed to a bucket of the digging machine. The IMU is mounted to the hollow enclosure and provides a space trajectory over time of the GPR antenna on the bucket as the digging machine is operated.

Radio frequency antenna and monitor

A ground penetration radar (GPR) antenna system is integrated into a digging machine such that the system is configured to remain operable under the same environmental conditions as the machine. The system includes an RF antenna and an antenna monitor. The antenna includes a rectangular hollow enclosure made of a conductive material defining a cavity therein and is affixed to a bucket of the digging machine. The antenna monitor is rigidly connected to the hollow enclosure and monitors inertial antenna location and/or movement.

A radio frequency (RF) antenna that may include a hollow enclosure made of a conductive material; wherein a first portion of the hollow enclosure has a bow tie shaped slot; a conductor that is spaced apart from the slot, is positioned within a cavity defined by the hollow enclosure, and is electrically isolated from the hollow enclosure; a first port that is coupled to the conductor; and a dielectric element that is made of dielectric material that at least partially fills the cavity and the bow tie shaped slot; wherein the conductor is configured to perform at least one operation out of: (a) receive, via the cavity, received RF radiation and send a received RF signal to the first port; (b) receive, from the first port, a transmitted RF signal and radiating transmitted RF radiation via the cavity.
