Abstract

A novel and compact ultra‐wideband (UWB) microstrip‐fed monopole antenna with frequency band notch function is presented in this study. Different from the conventional methods, a new method of inserting a lune‐shaped disk into the annular structure to achieve a notched band is proposed in this letter. The center frequency of the notched band can be adjusted with ease by tuning the length of the lune‐shaped disk. The designed antenna satisfies the voltage standing wave ratio (VSWR) requirement of less than 2.5 in the frequency between 3 and 40 GHz while showing the band rejection performance in the frequency band of 4.65 to 5.81 GHz. © 2009 Wiley Periodicals, Inc.
