Abstract

In this paper, an ultra-wideband (UWB) antenna with triple notch bands is pro- posed and well designed by etching an arc-shaped slot (ASS) on the fan-shaped radiating patch and integrating a U-shaped resonator (USR) alongside the microstrip feed signal line. The pro- posed antenna consists of a microstrip feed structure, a trapezoidal ground plane, a fan-shaped radiating patch, an ASS and a USR, which are printed on a thin substrate with dielectric con- stant of 2.65. The three band-notched characteristics are realized by the use of the ASS and USR, while the center frequencies of these notch bands are tunable by adjusting the dimensions of the proposed ASS and USR. By using these techniques, the proposed antenna can filter out unwanted narrowband signals from WiMAX, WLAN and RFID bands. The proposed antenna is well designed and extensively investigated. The experimental results are given to verify that the proposed antenna with a wide bandwidth, three designated band-notched functions and good omnidirectional radiation patterns, which is suitable for modern high data rate UWB communi- cation applications.
