A novel wideband circular slot antenna with tri‐band rejection characteristics at 2.45, 5.45, and 8 GHZ is proposed. Two different types of slots are used to obtain band‐notched characteristics at three frequencies; one is a split ring and the other is an inverted L‐shaped slot. These slots are employed inside a circular patch of the circular slot antenna and the rejection bands can be adjusted by selecting the lengths of two slots. It is demonstrated that tri‐band rejection characteristics at 2.45, 5.45, and 8 GHz with desired bandwidths can be obtained by using two different types of slots. © 2008 Wiley Periodicals, Inc.
