Electromagnetic propagation in unbounded inhomogeneous chiral media using the coupled mode method

Abstract

especially for the highest one. In addition, the measured data demonstrated that the proposed antenna maintains SWB characteristics, possessing a ratio bandwidth of 19.7:1 from 0.595 to 8.95GHz for VSWR Յ 2. The radiation patterns of the antenna were simulated and the results are very close to those of a conventional planar monopole antenna. The simulated peak gain is plotted in Figure 6, showing a low radiation level in the notched band. CONCLUSIONIn this paper, a rectangular monopole antenna having a band-notch function is presented for SWB applications. The study on the band notch function has been introduced in detail. Experimental results have shown an obvious rejected band in the WLAN frequencies.The bandwidth of the antenna covers 0.595-8.95GHz (15:1) for VSWR Յ 2, while the band rejection performance in the frequency band of 5.07-5.85 GHz is obtained.
