COMPACT DOUBLE BAND-NOTCHED ANTENNA WITH NONEQUIWIDTH W-SHAPED SLOT AND '6'-SHAPED RESONANCE LOOP FOR UWB APPLICATIONS

摘要

In this article, a novel compact double band-notched antenna with nonequiwidth W-shaped slot and "6"-shaped resonance loop on the two sides of the feed line is proposed, which consists of a cone-shaped monopole patch with nonequiwidth W-shaped slot and "6"-shaped resonance loop on the two sides of the feed line, the metal earth-plate with step slot is designed on other side of the substrate. The simulated and experimental results demonstrate that the proposed antenna can obtain the double band-notched feature within the bandwidth of 3.3-3.8 GHz and 5.0-6.0 GHz, the impedance bandwidth can achieve from 2.4 to 11.6 GHz (VSWR<2),which is more than 131%.
