A Via-Based Rectangular Patch Antenna for Narrow Band IoT Applications

Abstract

A simple asymmetric rectangular patch antenna has been projected for narrowband internet of things applications. A new via-based technique has been proposed to realize its bandwidth and increase the amount of transmitting power. And tuning aspects of this antenna has been explained for the radius of the copper via conductor. FR4 material has been utilized as dielectric material with loss tangent 0.02 with an effective dielectric constant of 4.259, and its performance has been explained under the different radius of the copper via. The designed antenna has a resonating frequency at 857.00 MHz, 879.00 MHz, 888.00 MHz, and 904.00 MHz at a different radius of the via with the bandwidths of 32.50 MHz, 29.40 MHz, 28.00 MHz, and 20.50 MHz. The proposed antenna has been simulated using HFSS and FEKO EM simulation tools.
