Design and Analysis of a Tunable Rectangular Microstrip Slot Antenna for Narrow Band Internet of Things Applications at 1800 MHz

Abstract

This chapter presents a tunable rectangular slot antenna on a Rogers RT/duroid 5880 (tm) substrate for narrowband internet of things applications. The proposed antenna has an operating frequency from 1601.20 MHz to 2051.90 MHz (tunable operating frequency range). The resonant frequency can be tuned by adjusting the length of the antenna as the application requirement. At each tuning step, the proposed antenna has sufficient bandwidth to fulfil the requirement of narrow band internet of things. The amount of power transmitting from the proposed antenna has been investigated at different aspects of the antenna. The proposed antenna has the ability to transmit above 99% at resonating frequency. All the analysis of the proposed antenna has been carried out in high frequency structural simulation. For the performance validation of the proposed antenna, it has been simulated in FEKO tool and its return loss behavior has been compared with HFSS results.
