Design of multiband Reconfigurable Inverted F-shaped antenna for Wireless applications

Abstract

This work presents the inverted F-shaped Frequency Reconfigurable Monopole Antenna, fabricated on low cost 1.6-mm thick dielectric substrate (FR4) having a partial ground plane. The designed antenna resonates at three single band frequency modes (2.1 GHz, 2.67 GHz and 3.8 GHz) as well as two dual band frequency modes (2.6 GHz, 5.5 GHz / 2.4 GHz, 5.3 GHz) using three switches. These reconfigurable band are used for valuable wireless communication applications, such as UMTS (2.1 GHz), Wireless Fidelity (2.4 GHz), 5G Mobile broadband (2.6 GHz), WiMAX (3.8 GHz / 5.5 GHz) and WLAN (5.3 GHz) and other wireless services. The proposed monopole antenna system comprises of Inverted F-shaped elements. The Reverse F-shaped is responsible for leading the higher frequency bands and F-shaped for lower frequency bands. The designed monopole antenna is simulated using Finite Element Method (FEM) employed in CST EM simulation tool-2020.
