DESIGN AND DEVELOPMENT OF EIGHT ELEMENTS SERIES-FED TWO DIPOLE ANTENNA ARRAY FOR OUTDOOR WLAN BASE STATION APPLICATIONS

Abstract
Antenna design is the key performance indicator in the development of wireless communication technology. In this paper, eight-element series-fed two dipole antenna array is developed for the outdoor WLAN base station applications. The proposed antenna operates at IEEE 802.11b standard 2.4GHz frequency band with the improved gain for supporting outdoor wireless local area network applications. A modified microstrip balun feeding is used for providing impedance matching. This antenna is designed on the FR4 substrate with dielectric permittivity of 4.4 and height of the substrate is 1.6 mm and loss tangent of 0.002 to achieve lower return loss. The dimension of the proposed antenna is 400?160?105mm3. This antenna is simulated in an integral based solver simulation software called CST Microwave studio v2020 and obtained results such as VSWR of 1.26, return loss of -18.26dB with Bandwidth of 200 MHz, Directivity of 15.4dBi, gain of 14.9dB, Port isolation is -16.5dB and an efficiency is of 85%. This antenna suitable for WLAN base stations used in larger coverage areas.
