Design and Analysis of a Connected E-Shape and U-Shape Dual-Band Patch Antenna for WLAN Application

This paper represents a numerical simulation of connected Eshape and U-shape for WLAN application. In this paper, dual operation E-shape and U-shape Patch Antenna is fed by transmission line. The objective in this design is to obtain the enhancement in bandwidth (BW) for WLAN applications over the frequency band (2 to 6 GHz).The proposed antenna is designed on two-layer, one FR4 substrate and another ground plane with an area of 33 mmx42 mm. The dual operation frequencies are 2.66 GHz and 5.72 GHz. In addition, the antenna has achievable return loss, radiation pattern and also bandwidths within the 6dB return loss bandwidth. It is observed that the impedance bandwidth can be expanded by using FR4 substrate. Furthermore, this antenna provides a stable radiation pattern across the operating bandwidth.
