Ultra-wideband (UWB) sensors are a radio frequency technology that use wireless communication between devices to precisely determine the position. The most recent applications focus on locating and sensor data collecting on mobile phones, car keys and other similar devices. However, this technology is still not being utilized in the mining sector. To overcome this gap, this perspective offers implementation options and solutions. Additionally, it evaluated the benefits and drawbacks of using ultra-wideband for mining. The measurements provided were made using QORVO two-way ranging sensors, and these were compared to theoretical and existing technological solutions. To ensure the optimal use of UWB sensors, a special emphasis was placed on certain influencing factors, such as ways of locating via UWB and factors affecting measurement accuracies, such as the line of sight, multipath propagation, the effect of shielding and the ideal measurement setup. A conducted experiment showed that the most accurate results are obtained when there is no multipath propagation and the arriving signal travels directly from the transmitter to the receiver.

“…Since the ruling of wideband technology by the Federal Communication Commission [1], the wideband antennas have drawn more attention for use in many applications such as modern high-speed wireless communication systems [2,3,4,5]. For example, different types of wideband antennas with relatively good performance in published works [6,7,8,9,10,11] have been developed.…”

A circularly polarized radial line slot array with enhanced bandwidth is presented in this letter. The proposed antenna consists of two parallel plates, a monopole probe and a spiral slot array. The parallel plates form a radial cavity and is fed by the probe. Then, the spiral slot array etched on the upper substrate can be excited by the radially outward wave to provide broadside radiation. In this design, the side wall of the cavity is left open, which helps to obtain wideband operation and has little effect on radiation patterns. To enhance the bandwidth further, a square cavity is used here to substitute for an initial circular one. With such a structure, the antenna is wide in bandwidth and compact in size. The proposed antenna is designed and fabricated. Measured results reveal that the antenna can provide an impedance bandwidth of 37.2% (15.1-22.0 GHz) and an axial ratio bandwidth of 31.0% (15.0-20.5 GHz), respectively. Additionally, the measured maximum gain is 26.7 dBic at 17.5 GHz.
