An Elliptical Folded Dipole With Directive Radiation for UWB Applications
Résumé
In this paper, a novel design of an elliptical folded dipole with a microstrip line to slot line transition is proposed for achieving high gain performance in ultra-wideband (UWB) receiving applications. The planar antenna, folded over a ground plane, exhibits a measured bandwidth of 2.3-26GHz with S11<-6dB and meets the S11<-10dB condition in several bands. Additionally, the simulated gain ranges from 5 dBi to 9.5 dBi across the entire bandwidth with an efficiency of at least 75%. The use of symmetrical feeding results in a directive radiation pattern. © 2023 IEEE.
