Microstrip Patch Antenna for the Applications of WLAN Systems using S-Band

Abstract

The popularity, demand, and necessity of WLAN systems are vastly growing day by day. Since WLAN systems' future requires higher gain and efficiency, considering that a rectangular microstrip patch antenna has been designed in this paper, which is carried out with the CST Studio Suite 2016 software. The proposed model has a better Return Loss (S 1,1 ) and a sound efficiency characteristic. The operating frequency of 2.3025 GHz (S-band) was applied here, one of the vital frequency bands for the WLAN systems. The patch's architectonic formation is 60.46*78.73*1.7 mm 3 , with the help of which a Return Loss (S 1,1 ) of -40.35952 dB, a gain of 5.93 dB, VSWR of 1.019375, and directivity of 6.992 dBi have been achieved. The determined efficiency of 84.81%, a bandwidth of 75.2 MHz, and a surface current of 35.65 A/m from the proposed model is a better WLAN system considering its healthy prospects. Considering these parameters, the designed antenna can be a worthy upgrade for the WLAN systems soon.
