Multiband Antenna Design Comprising the Future 5G Mobile Technology

Abstract

The pervasiveness of mobile internet, in conjunction to the ubiquitous computing of the internet-of-things has claimed the concept of 5G technology research to allow massive growth of machine communications. One of the main challenges is the scalability problem, which implies issues like small mobile device antennas to fit in the limited amount of space for the smartphone's design, followed by radiation control and low cost. The purpose of this paper is to develop an antenna, which meets the next generation of the mobile technology 5G as well as other resources available and desired in a smartphone (GPS-1575 MHz, WLAN-2.4 GHz, 3G-2.1 GHz, Brazilian 4G-2.6 GHz e GSM-900-1800-1900-2100 MHz). The design adopted only one ultra-wideband microstrip antenna that resonates in the frequencies of these technologies. This kind of antenna is thin, has low cost and good radiation control. Besides, this is the most popular type of antenna in mobile devices; the radiant elements use the manufacturing process of printed circuits. It is built in a plate composed by a conductor (the radiant element of the antenna), a substrate, and by another conductor, which is the ground plate. The principal feature of an ultra-wideband antenna is the usage of 1.5 GHz bandwidth or more. The prototype was manufactured and the simulation results for each type of technology resources are compared.

Design and Analysis of a Low-profile Microstrip Antenna for 5G Applications using AI-based PSO Approach

“…A graphene-packed dual band mmWave antenna for 28.1 GHz and 37.4 GHz with a DC bias was proposed by Luo et al [13]. A tiny, portable ultra-wideband microstrip antenna for 5G applications was developed by Araujo et al [14], while a small and dual-polarized triple-band antenna for sub-6 GHz 5G applications was created by Alieldin et al [15]. Naji demonstrated in [16], three fork-shaped monopole-based CPW-fed MPAs: SFA, MFA, and DSFA.…”

A Comprehensive Review on Multi-band Microstrip Patch Antenna Comprising 5G Wireless Communication

“…Araujo, Freitas, Prata, Casella and Capovilla [28] realized a thin and compact ultra-wideband microstrip antenna which resonates at 5G as well as 1575 MHz for GPS, 2.4 GHz for WLAN, 2.1 GHz for 3G, 2.6 GHz for Brazilian 4G, 900-1800-1900-2100 MHz for GSM wireless communication applications. The antenna offers good radiation control with 1.5 GHz or more bandwidth usage.…”

Multiband Handset Antenna System for UMTS/LTE/WLAN/Sub-6 5G and mmWave 5G Future Smartphones

“…Smartphones have been rapidly developed during the last decade where many services have been added and integrated into one single device. This has been accomplished by incorporating several technologies in one device such as the global system for mobile communication (GSM), 3G & 4G, Wi-Fi, and Bluetooth [2,3]. By increasing the demand on utilizing more applications of the internet of things (IoT), another demand is emerged on designing systems that provide high data rates to cope with the rapidly emerging IoT requirements.…”
