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 lame-shaped radiator. The effect of the slot is investigated. We discover that the slot can he 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 cc bandwidth front 2.65 to over 12 GHz with VSWR < 2. (C) 2009 Wiley Periodicals, Inc.
