DESIGN AND DEVELOPMENT OF FOUR ELEMENT SERIES-FED TWO DIPOLE ANTENNA ARRAY FOR WLAN BASE STATION APPLICATIONS

Abstract
Antenna design is the primary stage for development of wireless communication technology. In this paper, four element series-fed two dipole antenna array is developed for the WLAN base station applications. The proposed antenna operates at IEEE 802.11b standard 2.4GHz frequency band with reduced size and improved gain for supporting 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 1.6mm and loss tangent of 0.002 to achieve lower return loss. The dimension of the proposed antenna is 160*105*160[mm]^3. This antenna is simulated in an integral based solver simulation software called CST Microwave studio v2018 and obtained results such as VSWR 1.3, Return loss -18dB with Bandwidth of 200MHz, Directivity of 12.5dBi, gain of 11.9dB, Port isolation is -16.5dB Efficiency of 90%. This antenna suitable for WLAN base stations used in larger coverage areas.
