A compact sierpinski-carpet-based patch antenna for UWB applications

In this paper, we propose a low-cost small-sized microstrip antenna based on a trapezoidal connection between a double-Sierpinski-carpet-shaped (2
^nd
iteration) patch and an I-shaped feed line. The ground plane is partial and is flushed with the feed line. The fundamental characteristics of the proposed design over the UWB frequency band are illustrated herein.
