A novel monopole-type antenna, which covers the bandwidth 3.1 10.6 GHz is presented. The shorted and folded planar monopole antenna is constructed by folding a thin copper sheet in such a way that one edge of the radiating element is connected to the ground plane. Simulated and measured results show suitable characteristics for communications systems using ultrawide-band (UWB) technology. Moreo...

The design of a simple small-size antenna for worldwide interoperability for microwave access (WiMAX) application is presented in this paper. The antenna covers the 3-5 GHz WiMAX band.

An offset T-shaped slot dual functions employed to improve the bandwidth of one element and enhance isolation. Then, double L-shaped stubs are loaded impedance matching other MIMO antenna. Finally, 2 × constructed by four monopole antennas, t...

A planar monopole antenna suitable for broadband wireless communication is designed and developed. With the use of a truncated ground plane, the proposed printed monopole antenna offers nearly 60% 2:1 VSWR bandwidth and good radiation characteristics for the frequencies across the operating band. A parametric study of the antenna is performed based on the optimized design, and a prototype of th...

Micro strip antennas have been the subject of some inventive work in recent years, and are currently one of the most dynamic fields in antenna theory. A single wideband, E-shaped, compact microstrip antenna is presented in this article in order to be employed for high speed WLANs operating in the C band range. Employing only a single patch, a high impedance bandwidth is achieved. The simulated ...
