摘要：In this paper, a novel ultrawideband (UWB) antenna is proposed. This proposed antenna is microstripfed in design. The proposed antenna has dual band characteristics for Wideband Code Division Multiple Access ,WCDMA ( 1.92.1 GHz) at the center frequency of 2 GHz and Xband (812 GHz) with resonant frequency of 10 GHz. The design of proposed structure comprises of a rectangular patch and two inverted and identical rectangular strips. A rectangular patch design is employed to operate antenna on UWB frequency band from 3.110.6 GHz. The dimensions of proposed antenna is also minimized to increase the antenna gain and high impedance bandwidth. On the back side of antenna, a ground plane is designed. The ground structure is modified and connected with two inverted Lshaped strips to obtain the dual band characteristics resonant at 2 GHz and 10 GHz respectively. The proposed antenna is designed using FR4 substrate of compact dimension 25 mm × 25 mm × 1.6 mm. The microstrip antenna is fed by 50 Ω. The simulated results of proposed antenna are good and shows neary omnidirectional radiation pattern, constant gain, small group delay. The return loss (S11) is < 10 dB and VSWR is also < 2 throughout the UWB band. At 2 GHz and 10 GHz resonant frequencies, the S11 are 21dB and 23dB respectively. The designed antenna configuration is simulated and analysed by using high frequency structure simulator (HFSS).
