Range Distance Measurements Using an UWB Tapered Slot 0.43 GHz to 6 GHz Antenna for IoT Application

This paper presents a compact and innovative design of a UWB radar sensor. The basis of the proposed UWB short pulse generator is a driver, a pulse sharpened and a Monocycle-forming network MFN. The driver converts the step-like waveform in Gaussian pulses, and the pulse sharpened converts slow rise time waveform edge to a faster one. However, the pulse-forming network forms the adequate and required pattern: Gaussian or monocycle. The purpose of this work is to design and fabricate a high-power and low-cost monocycle pulse generator with high accuracy in order to use it on the Internet of Think application especially for applications in The-four-generation-of-industry. To overcome this challenge, a useful technique has been employed; this technique consists of making the discharge path as short as possible, the measurement results give an output waveform of 0.7 volts in amplitude with a minimum ringing around 3:6% in overshoot at 1 MHz. The generator circuit is completely fabricated using micro-strip structure technology characteristics. Good agreements between the measured and theoretical results are achieved which can consider very attractive in many application fields, especially in IoT Application. (C) 2019 The Authors.
