This paper presents a new technique to improve the impedance bandwidth of a rectangular planar monopole. The method involves beveling one part while keeping the other edges near the ground plane, which is connected to the antenna‐feeding port. The measured impedance bandwidth of the monopole can reach a ratio of 14:1 for a voltage standing wave ratio (VSWR) equal to 2:1. The measured radiation patterns of the antenna retain the typical monopole characteristics throughout the bandwidth. © 2005 Wiley Periodicals, Inc.
