A Novel Design of Microstrip Monopole Antenna for UWB Applications

This paper presents the design and analysis of a microstrip monopole antenna for ultra-wideband applications which are illustrated through simulations in HFSS. The proposed antenna operates in a frequency band 4.3 GHz to 11.6 GHz which covers the C band and X band. A return loss of more than 10dB is observed in this frequency band. This antenna exhibits dual resonance with a return loss of 35 dB observed at the resonant frequency 5.4 GHz and a return loss of 34 dB observed at another resonant frequency 9.4GHz. The maximum gain is 1.3dB at 5.4GHz. This antenna is suitable for radar applications, satellite communication and other wireless computer networks.
