Development and analysis of microstrip antenna for Wireless Local Area Network (IEEE 802.11y)

This paper presents a compact narrow band antenna for Wireless Local Area Network (WLAN) which operates at 3.6 GHz. The proposed antenna has M-shaped structure with length (l) of 35.89 mm and width (w) of 22.99 mm respectively. In this, selection of the patch length and width are the major parameters taken into considerations when designing an antenna. Desired patch is initially simulated by using IE3D simulator and is realized as per design requirements. This antenna provides return loss of -20 dB while the -10 dBpassband of the developed antenna is 1GHz from 3.5GHz to 3.7 GHz. the designed antenna is fabricated on FR4 substrate with dielectric constant of 4.4, loss tangent of 0.0004 and thickness of 1.6 mm using dual side Printed Circuit Board (PCB) technology. The measured S parameter of an antenna is compared with the simulated one, where the results obtained over the desired passband is at acceptable level.
