DESIGN AND DEVELOPMENT OF SERIES FED TWO DIPOLE ANTENNA FOR WLAN BASE STATION APPLICATIONS

Abstract
Antenna design is the crucial process in the development of any devices in wireless communication Era. In this paper, Series-Fed Two Dipole Antenna is designed for the WLAN applications. The proposed antenna operates at 2.4GHz frequency band which is IEEE 802.11b, industrial, scientific and medical (ISM) band with reduced size and improved gain for providing effective access to wireless internet to the end users. A modified balun feeding is used for improving impedance matching. This antenna is designed over the FR4 substrate with dielectric permittivity of 4.4 and height of the substrate is 1.6mm to achieve lower return loss. The dimension of the proposed antenna is 105mm length 80mm width. This antenna is simulated in an integral based solver simulation software called CST Microwave studio v2017 and achieved best results such as VSWR 1.25, Return loss -19 dB and Bandwidth of 200MHz, Directivity of 6.71dBi, gain of 6.19dB. This antenna finds its applications in WLAN Base Stations and wireless access points.
