Octaband antenna for mobile applications

Rajarajan K 1, Sudarsanan S 2

Abstract

An octaband micro strip antenna is designed that integrates the current wireless technologies with some of the older and upcoming technologies of the mobile communication. It provides backward compatibility to the technologies like 2G, 3G. It operates in all the three Wi-Fi bands, the proposed 5G band at 3.3 to 3.4 GHz (lower 5G bands) and the Wi-Max band. It is designed with copper as the conductive material and FR-4 as the substrate. Defective ground structure (DGS) has been implemented to improve the return losses. This antenna radiates at 8 different frequencies which are: 2G (1.8 GHz), 3G (2.1 GHz), 4G (2.3 GHz), 5G (3.3GHz), Wi-Fi (2.4 GHz,5.0GHz,5.9 GHz), and Wi-Max (4.2 GHz).
