Abstract

This paper presents the design and performance evaluation of a planar ultra-wideband (UWB) antenna employing an elliptical dipole structure, targeting comprehensive omnidirectional coverage within the 1-10 GHz frequency band for 5G Internet of Things (IoT) applications. The antenna, constructed on a cost-effective FR4 substrate, exhibits an impressive impedance bandwidth of 10:1 (S₁₁ ≤ -10 dB) and frequency-dependent gain ranging from 3 to 8 dBi. Its design features ensure minimal side lobe levels below -20 dB, contributing to enhanced signal integrity and reduced interference. Notably, the azimuthal plane radiation pattern maintains a remarkable 1 dB out-of-roundness, facilitating robust communication in diverse IoT environments. Extensive 3D radiation pattern measurements affirm the antenna's effectiveness in optimizing signal propagation and reliability across varying deployment scenarios. This study underscores the significance of the elliptical dipole configuration in advancing UWB technology, highlighting its potential for seamless integration into future 5G IoT networks.
