Abstract

Considering the ever-increasing and high demands in wireless communication applications for 4G, L TE, and 5G, a proposed antenna design has been put forth that incorporates dual-band millimeter wave technology with the sub-6 GHz band. This design has been expertly created to cater to the growing needs of the telecommunications industry and aims to effectively meet the requirements of modern-day 5G applications. The integration of dual-band millimeter wave technology with the sub-6 GHz band offers a seamless user experience and improved network reliability. The round-shaped antenna boasts four inverted-cone slots located at the center of the circle and is connected to a radiating patch element at the top front. This element features a square slot shape and is complemented by a partial ground plane to optimize its functionality and performance. The antenna is designed on a Rogers 3003 substrate, 2.2 dielectric constant with dimensions of35 mm x 25 mm x 1.52 mm, and a loss tangent of 0.0009 using a CST microwave Studio. This antenna boasts an impressively wider bandwidth of 8.293 GHz, spanning from 27.009 to 35.302 GHz. Additionally, a bandwidth of 1.54 MHz (between 2.23 GHz and 3.77 GHz) was observed at the sub-6GHz band. Notably, the antenna also exhibits impressive return loss values of -36.46 dB and -30.44 dB at the sub 6GHz band (3.5 GHz) and millimeter wave band (28 GHz), respectively. This antenna, despite its small and compact size, can combine two discrete frequency bands, namely the millimeter wave band and the sub-6 GHz band. Notably, the frequency ratio between the two aforementioned bands stands at 8, which is a remarkably large ratio.
