Dual band‐notched ultra‐wideband printed antenna with two different types of slots

Abstract

Abstract A compact wideband printed antenna with dual band‐notched characteristics for wireless local area network (WLAN) (2.4 GHz/5.8 GHz) is introduced.It is demonstrated that dual band rejection characteristics at 2.4 and 5.8 GHz with desired bandwidths can be obtained by using two different types of slots, one is a folded stripline slot on the radiation patch, and the other is a pair of inverted‐L‐shaped slot on the ground. The proposed antenna operates over 2.2–11 GHz for VSWR <2, while providing a band‐stop function in the frequency bands of 2.3–2.9 GHz and 5.5–6.3 GHz. © 2010 Wiley Periodicals, Inc.
