This study theoretically analyses the transmission performance of UWB antennas and presents a design methodology for improving the transmission performance of printed monopoles. Using this methodology, a modified circular monopole are proposed and analyzed as the design example. Both measured and simulated results are provided and discussed for verifying the validity of proposed design methodology. In a typical lab environment, the deleterious multi‐path transmission effects on the transfer function of the example antenna pair were observed and discussed. This optimization methodology would not bring any size or cost increase to the printed monopoles, and the improvement of transmission performance is quite discernible, which appears to be a significant improvement over printed UWB monopoles. © 2008 Wiley Periodicals, Inc.
