A simple method for the design of ultra‐wideband antennas in planar format is presented. This method is demonstrated for a high‐dielectric‐constant substrate material, which allows for a considerable antenna size reduction. Simulations are performed using Ansoft's High‐Frequency Structure Simulator (HFSS) for antennas assuming DuPont951 (ε r = 7.8) and RT6010LM (ε r = 10.2) substrates. For the 1‐mm‐thick DuPont951, the designed antenna with 22 × 28 mm dimensions features a 10‐dB return‐loss bandwidth from 2.7 GHz to more than 15 GHz. For the 0.64‐mm‐thick RT6010LM a 20 × 26 mm antenna exhibits a 10‐dB return loss bandwidth from 3.1 to 15 GHz. Both antennas feature nearly omnidirectional properties across the whole 10‐dB return‐loss bandwidth. The validity of the presented UWB antenna design strategy is confirmed by measurements performed on a prototype developed on RT6010LM substrate. © 2006 Wiley Periodicals, Inc.
