A New Compact Printed Triple Band-Notched Uwb Antenna

Abstract

Abstract-A novel planar ultra-wideband (UWB) antenna with triple-notched bands using triple-mode stub loaded resonator (SLR) is presented in this paper. The basic UWB antenna consists of a circularshaped radiating element, a 50 Ω microstrip feed line, and a partially truncated ground plane. Then, the resonance properties of the SLR are studied. Results reveal that the multiple-mode property of the SLR can be utilized in the UWB antenna design to achieve triple band-notched performance. To validate the design concept, a novel planar UWB monopole antenna with three notched bands respectively around the WiMAX band, WLAN band, and X-band satellite communication band is designed and fabricated. The results indicate that the proposed planar antenna not only retains an ultrawide bandwidth, but also owns triple band-rejections capability. The UWB antenna demonstrates omnidirectional radiation patterns across nearly whole operating bandwidth that is suitable for UWB communications.

A Compact Notched Uwb Mimo Antenna With Enhanced Performance

“…High data rates and better Quality of Service (QoS) are the main concerns of future wireless communication systems. In April 2002, the FCC approved ultra-wideband (UWB) that lies within 3.1 to 10.6 GHz for the commercial use [1]. The use of UWB technology is encouraged in wireless communication, as it is one of the most favorable techniques for improving data rate.…”

Usage of Shaped Stubs for Mutual Coupling Reduction in A MIMO Antenna

“…In April 2002, the FCC approved ultra-wideband (UWB) that lies within 3.1 to 10.6GHz for commercial use [1]. Ultra Wideband (UWB) technology has gained much importance in the recent times because of its ability to use a very low energy level for shortrange, high-bandwidth communications over the radio spectrum high data rate and its low cost of fabrication made it as a useful application in mobile and wireless communication.…”

“…In [9] and [11], minimum number of notching elements used for creating triple band notches is one, but sizes of the antennas are bigger than the proposed antenna. The proposed design uses three notching elements and has dimensions 26 × 27 × 1.6 mm 3 equivalent to 0.24λ × 0.23λ × 0.01λ with respect to the first resonance frequency at 2.7 GHz which is compact in size as compared to all the references taken, and hence, is a good candidate to be integrated in miniature UWB portable devices.…”

“…To keep the antenna footprint unaltered, effective ways to achieve band rejection behavior are inserting strips or slots of various shapes and sizes in the radiating patch/ground plane [2,12] or embedding a tuning stub within a large slot on the patch [4]. Methods using open loop or split ring resonator [3,5,6], inserting the band-rejecting elements integrated in the feed line [7,13], capacitance loaded loop resonator [8], triple-mode resonator [9], electromagnetic band gap structures [10], and triple mode stub loaded resonator [11] have also been presented.…”
