Design and development of antenna is the first step in improving overall effective coverage area of wireless communication. In this paper, two element series-fed two dipole antenna is designed for the WLAN base station applications with improved mutual coupling. The proposed antenna operates at IEEE 802.11b standard 2.4 GHz frequency band with reduced size and improved gain for increasing effective access to wireless internet to the end users in wireless communication. 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 105 mm length 160 mm width. This antenna is simulated in an integral based solver simulation software called CST Microwave studio v2018 and achieved best results such as VSWR 1.3, return loss -16.56dB and bandwidth of 200MHz, directivity of 9.26dBi, gain of 8.68dB and an efficiency of 70%. This antenna suits for WLAN base stations.
