Abstract

In this paper, a printed elliptical slot antenna fed by different tapered microstrip line with U-shaped and Circular ring-shaped tuning stub is proposed for ultra-wideband (UWB) applications. The tapering aids in minimizing the reflection at the interface between the microstrip feed line and the tuning stub. Introduced is a new tapering profile that minimizes the reflection and hence enhances the bandwidth. The tapering profile is based on the Willis-Sinha profile. The design parameters for achieving optimal performance are investigated. The operation and the performance of the proposed antenna are also analyzed. Good agreement between simulated and experimental results is obtained.
