A novel wideband polarization diversity antenna without parasitic elements is proposed. The diversity antenna is simply composed of a balanced, printed dipole and a modified tapered slot antenna. The antenna is numerically and experimentally studied for its performance. As will be reported, the diversity antenna's operation bandwidth is from 5.04–11.85 GHz, in which the average isolation between the...
Design concept of a novel, dual-band balanced antipodal ultra-wideband antenna is proposed. The antenna is composed with a symmetrical dipole and balanced tapered slot radiators and can be directly integrated with differential microwave circuits. Operation principle and performance of the antenna, such as return loss, radiation patterns and gain, are simulated and analyzed. As will be presented, the...
Design concept of a compact, novel ultra-wideband (UWB) 2-element antenna array having polarization diversity function is proposed and numerically studied. The array is composed with a monopole antenna and a symmetrical dipole-slot antenna. The array is numerically studied for its return loss, element isolation, radiation patterns and gain. The array is also compared with conventional wideband polarization...

Novel arc-shaped antipodal slot antenna fed by microstrip line with an elliptical tuning patch for ultra-wideband (UWB) applications is proposed. Arc-shaped half-folded antipodal structure is employed to improve the radiation characteristics of the antenna. The antenna has been investigated numerically and experimentally and compared with conventional rectangular wide slot antenna. As is reported,...
This paper, a novel half-folded antipodal slot antenna fed by microstrip line is proposed. A half-folded tapered slot and patch-like tuning stub is employed to achieve both wideband and low cross-polarization performance. For comparison, a reference rectangular slot antenna fed by microstrip line is also designed, fabricated and measured. As is reported, the operation bandwidth of this antenna is...
A compact diversity antenna for Ultra-wideband applications is proposed. The proposed antenna is composed of two square monopoles. In order to reduce the mutual coupling between the two elements, A T shape stub is introduced. The antenna has been investigated numerically. As is reported, the operation bandwidth of the antenna is from 3.3GHz to 10.4GHz. Good isolations can be achieved. It may be useful...
A printed diversity antenna for ultra-wideband applications is proposed. The proposed antenna is composed of two square monopoles. In order to reduce the mutual coupling between the two elements, A cross shape stub is introduced. The antenna has been investigated numerically.
