A Modified Wideband Bow-Tie Antenna with DGS for Wireless Fidelity Range

In this research work design a modified wideband bow-tie antenna for Wi-Fi ranges. Now a day's demand of wireless device increases in rapidly due to require a wide range application antenna. Wide band antennas are those antennas full fill the demand of current generation communication devices. In this presented research work design a bow-tie antenna for 1 to 6 GHz frequency range. In this current generation most of the wireless devices exist in this range. This research work shows Bow-Tie Shape antenna with bow shape slot. In slotted Bow-Tie antenna on patch side, and apply defected ground structure on the ground side. On the ground side apply two right angle cuts with parabolic cut on the ground side. For the enhancement of bandwidth apply CPW feed in the structure and obtain enhanced bandwidth as well as return loss. The proposed bow-tie antenna shows result in the range of 3.0 GHz to 4.87 GHz range and the total bandwidth obtain 1.86 GHz. In this region got two impedance frequency on 3.47 GHz and 4.41 GHz with return loss is -32.45 dB and -34.45 dB. Designed antenna is shows wide band (WB) nature also shows dual band nature. The result of proposed design show good return loss as well as VSWR.
