Abstract
This paper proposes a novel Super Ultra Wideband (S-UWB) monopole printed microstrip antenna. Analysis of tapering the feedline of S-UWB antenna is done to study the various parameters like return loss (S 11 ), Voltage Standing Wave Ratio (VSWR), Gain and radiation pattern. Study shows the improved performance of S 11 , VSWR as well as gain by tapering the feedline. The associated 10 dB bandwidth of the proposed antenna is from 1–35 GHz. The volume of the proposed antenna is 40 x 50 x 1.6 mm3 with substrate as FR-4 epoxy having the permittivity 4.4 and loss tangent 0.02. The return loss (S 11 ) less than −10dB), VSWR and radiation pattern shows in good agreement with the bandwidth. The proposed antenna is designed, simulated and optimized using HFSS commercial software. Investigation of S11 and VSWR is done for various tapered feedline to study the effect on its 10dB bandwidth. This proposed antenna is capable of covering the satellite navigation, UMTS, Bluetooth, PCS, WiMAX2500, LTE2600 Surveillance RADAR and UWB/S-UWB applications.
