Design of Dual Band Monopole Antenna Using Defected Ground Structure

Mahesh H. Jadhav | Prof. V. U. Deshmukh

Abstract: A novel dual band monopole antenna using defected ground structure is proposed. DGS is used to increase bandwidth, the designed antenna operate at the frequency range 1.92- 3.04 GHz, 4.6 -5.8 GHz which suitable for WLAN and WiMAX application. The proposed antenna has a small size and can be easily fed by 50 ohm microstrip line. The designed proposed geometry is simulated by using HFSS software. The simulation result shows that the antenna gives the monopole like radiation pattern and it achieves return loss -20.3 and -19 dB at 2.4 and 5.3 GHz frequency respectively with FR4 substrate. The result gives the satisfactory performance.
