摘要

Spiral-shaped UWB antennas, which are differ from each other in terms offeeding structure are presented in this manuscript. CPW and microstrip linefeeding are used to excite the designed antenna to obtain different performanceparameters. The overall physical dimensions of proposed antennas are27 × 27 × 1.6 mm~3. These antennas are designed on low cost FR4 glass epoxysubstrate with 1.6 mm thickness and dielectric constant 4.4. Impedance bandwidth(S_(11) < −10 dB) obtained for measured CPW-fed antenna is 176.82%ranging (1.23-20.0 GHz) and microstrip line-fed antenna is 169% ranging(1.68-20.0 GHz). Various performance parameters of both the designed antennasare observed and calculated, such as, radiation pattern, gain, group delay,and radiation efficiency, which all are in the acceptable range for distinctUWB communication and other wireless standards. The optimized designedantennas are fabricated and tested for the validation of results and comparisonamong simulated and measured results of antennas have been made andfound in good agreement with each other.
