A NOVEL MONOPOLE ANTENNA WITH A SELF-SIMILAR SLOT FOR WIDEBAND APPLICATIONS

摘要

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.
