A Multiband Antenna For Gsm, Wlan, S-Band Radar And Wimax Applications

Abstract

The futuristic technologies needs the low profile and compact multiband antenna for their applications as the size of the communication devices are reducing significantly. In this manuscript, a patch antenna is intended over Flame Retardant (FR4) substrate and then Defected Ground Structure (DGS) as well as Defected Microstrip Structure (DMS) were introduced in it, which increases the number of resonant frequencies and their return loss. Coaxial feed was utilized in this plan. The designed antenna radiates efficiently for the applications like Global System for Mobile Communications (GSM) at 1.8 GHz resonant frequency, WLAN with 2.4 GHz resonant frequency, S-Band Radar by means of 2.9 GHz resonant frequency and WiMAX standard by the side of 3.4 GHz resonant frequency. High Frequency Structural Simulator (HFSS) was utilized for the simulation of the projected antenna design.
