In this paper, we have investigated printed monopole antennas, which is basically printed microstrip antenna with etched ground plane for UWB applications. In particular, we have simulated two types of UWB printed monopole antennas: circular and modified circular disk monopole antennas. Simple rectangular microstrip lines are used for feeding the printed monopole antennas. This UWB monopole ant...

Several wideband antennas are presented for either wireless application. This paper presents the performance of a simple monopole antenna loaded with an annular dielectric resonator as a wideband transmitting/receiving antenna. By adjusting the length of the monopole and load arm, a 10-dB bandwidth of 94% is achieved while maintaining monopole-like radiation pattern, which covers UWB applicatio...

Abstract—This paper presents a planar microstrip-fed tab monopole antenna for ultra wideband wireless communications applications. The impedance bandwidth of the antenna is improved by adding slit in one side of the monopole, introducing a tapered transition between the monopole and the feed line, and adding two-step staircase notch in the ground plane. Numerical analysis for the antenna dimens...
