A compact printed monopole Ultra-Wideband antenna with three subband notches is proposed and analyzed in this paper. The proposed antenna has the bandwidth from 3 GHz to over 11 GHz. By using two simple types of slot, triple subband-notched characteristic is obtained. A simple straight slot is etched on the radiating patch to acquire the subband notch at 3.3-3.7 GHz for WiMAX band. In addition, three...
This paper has presented a method of size reduction of the CRLH transmission line antenna by using a magneto-dielectric material. The CRLH-TL antenna is composed of two patches and vias, and the magneto-dielectric material is constructed by split ring resonators. The resonant frequency of the antenna is reduced by using the magneto-dielectric material: 7.34% at -1st-order mode and 24.88% at zeroth-order...
An input impedance matching technique of a Fabry-Perot (FP) high gain antenna is introduced and demonstrated. By inserting two stubs aligned with the electric fields of the patch antenna, vertically, between the superstrate and the patch, and by adjusting the stub geometry, the input impedance of FP antenna can be matched easily. The FP antenna with the stub has been simulated for different resonant...
