Design and analysis of dual band star shape slotted patch antenna

Abstract : This article proposes a new dual-band patch antenna for applications in the wireless local area network (WLAN) using MIMO technology. It consists on star shape slotted microstrip patch antenna, using FR4 substrate. The rectangular slotted patch uses microstrip feed line of 50 Ω characteristic impedance. This designed antenna can operates at 2.4 and 5 GHz resonant frequency. The dual band characteristic is obtained by integration of two open or partial star-shaped slots on the upper side of the patch and the third star slot is embedded in the center of the patch. In order to optimize characteristics of this patch antenna, "Computer Simulation Technology" Software (CST) is used. The results of simulations show that the proposed antenna covers the operating bands of 2.41 GHz (2.38-2.45 GHz) and 5.075 GHz (4.98-5.16 GHz), with return loss S[1,1] < -10dB, also it presents a good omnidirectional radiation pattern, who meets the requirement of WLAN applications.
