Abstract

A 2.44 GHz high gain circular polarized (CP) patch antenna is designed, fabricated and tested for operation while mounted on a rotating cutting drum of a mining or excavation machine. This design incorporates a radiating element that is elevated above the ground plane to increase the antenna gain. The design utilizes a single feed source and a square truncated corner patch to produce CP radiation. The gain of the final design reached 9 dBi with a sufficiently CP axial ratio and more than −25 dB cross-polarization isolation. This system enables the data communication between the rock cutting tools installed on the machine and the unit to enable the remote monitoring of tool conditions as well as identification of the formations being mined.
