ANALYSIS AND DESIGN OF A TRIPLE BAND-NOTCHED UWB ANTENNA BASED ON COMPLEMENTARY SPLIT RING RESONATOR
RÉSUMÉ
In this paper, an ultra-wideband (UWB) antenna with triple band notched characteristics is presented. The proposed reference antenna is composed of a circular radiating patch, a 50 Ω microstrip feed line, and a partially modified ground plane to enhance the impedance bandwidth. Two CSRRs are used to achieve the stop band function. A single CSRR is incorporated in the radiator to notch a bandwidth from 3.3 to 4.3 GHz for both WiMAX and C-band. The WLAN (5-6 GHz) and the X-band (7.25-8.4 GHz) are rejected by etching a codirectional CSRR in the ground plane with a CSRR slot in the substrate as method to improve the rejection level. The key parameters of CSRRs are investigated and exploited in the optimization process. Simulated results show that the proposed antenna has a wide impedance bandwidth (2.8–13.2 GHz), stable radiation patterns, and constant gain which make it a promising candidate for UWB applications with band notched features.
