A novel hybrid design of microstrip-fed parasitic-coupled monopole antenna is presented. The proposed antenna structure consists of a directly fed main patch and electromagnetically coupled parasitic patch, both in the semi-ellipse shape. Wider impedance bandwidth can be achieved by carving two sectors on bottom-side of the parasitic patch. An additional inverted semi-ellipse-shaped patch is connected...
As wireless communications applications continue to require more and more bandwidth, there has been continued increase in demand for ultra-wide bandwidth antennas. Planar monopole antennas are generally suitable for mobile applications and hence we researched avenues to improve the bandwidth of this antenna structure. First part in this paper describes the design of novel compact and ultra-wide bandwidth...
In this paper, the design, simulation and measurement of UWB antenna is presented. Fundamental considerations in UWB antenna design were outlined, with emphasis on the extra constraints placed on antenna design by ultra wideband operation. Several parameters were taken into account in analyzing strengths and weaknesses in the potential antenna designs including impedance bandwidth, radiation pattern,...
A modified small-size tapered monopole antenna is optimized for ultra wideband applications in co-design with the transceiver. Our optimization procedure aims at finding an antenna not only with low VSWR, but also miniaturizing the antenna at the same time. Our proposed optimization algorithm, real-coded compact genetic algorithm, RCCGA, has lowered the antenna area more than 48% compared to previous...
A compact vertical circular disc monopole (CDM) antenna with U-shape slot and inverted U - shape slot (radius, a=1.5 cm, thickness, t=0.02 cm, height gap, h=0.01 cm and the ground plane size of 14 cm2) is presented in this paper. The CDM antenna has been reported to yield wide-impedance bandwidth, good radiation efficiency and one of the best candidates for ultra wide band (UWB) antenna system. The...
