In this article, a printed flame‐shaped monopole antenna with a self‐similar slot for wideband application has been presented and investigated. The wideband characteristic is easily achieved by inserting a self‐similar slot in the flame‐shaped radiator. The effect of the slot is investigated. We discover that the slot can be effectively used for bandwidth enhancement, while the position of the slot has a negligible effect on the performance of the proposed antenna. Experimental results show that the proposed antenna obtains a bandwidth from 2.65 to over 12 GHz with VSWR < 2. © 2009 Wiley Periodicals, Inc.
