Broadband Printed-Dipole Antenna for 4G/5G Smartphones

Abstract

Nowadays, mobile communication systems are required to provide larger bandwidth and higher data rates to accommodate the increasing number of subscribers, and the vast amount of data handling. The fifth generation (5G) requires higher frequency bands as the sub-six and the millimeter bands. New designs for antennas are expected to fulfil these requirements in addition to covering the current mobile systems. Thus, there is an increasing demand to design antennas that cover both 4G and 5G bands for mobile communication systems. In this paper, a novel design based on monopole antenna of various shapes and dimensions is introduced. The single-element antenna yields an |S11| better than -6-dB over the operating frequency bands of (1.24 GHz- 2.64 GHz) and (3.34GHz- 5 GHz) with gain and efficiency of 5 dBi and 80% respectively. So, the proposed antenna covers 23 bands of the total (32) 5G NR bands in addition to 30 LTE bands.
