✦ Synopsis

Abstract

A novel spade‐shaped microstrip‐fed ultrawideband planar monopole antenna with dual band‐notched characteristics is presented. Dual narrow band‐notched characteristics are achieved by employing an Ω‐shaped slot on the radiating patch and a split‐ring resonator on the backed side. Experimental results demonstrate that the proposed antenna satisfies the voltage standing wave ratio requirement of less than 2.0 in the frequency band of 3–12 GHz, except two frequency stop‐bands of 3.3–3.9 GHz and 5.70–6.05 GHz. Moreover, measured group delay and transmission characteristics indicate that the proposed antenna has good transient response. © 2009 Wiley Periodicals, Inc.
