The ultra-wideband (UWB) antennas are required to cover high impedance bandwidth such that the return loss (RL) is greater than 10 dB with improved gain and radiation efficiency which are required for the different applications. In this UWB range (3.1–10.6 GHz), there are other applications, using narrow band frequency bands, such as WiMAX (3.3–3.7) GHz, WLAN (5.15–5.825) GHz and others. In this case...
In this paper, we propose a micro-strip antenna design for ultra-wide band (UWB) applications. The antenna has a deformed rectangular patch with diagonal cuts and circular edges replacing the sharp edges, a 50 Ω micro-strip feed line and partial ground with a single rectangular groove. These modifications were used to improve the bandwidth to up to 128%. The simulated parameters and analysis of the...

A compact single notch microstrip-fed monopole ultra-wideband (UWB) antenna with bandwidth (BW) enhancement is proposed. To improve the impedance BW, a rectangular slot is etched in the bottom edges of a rectangular radiating patch and the feed line is modified in staircase manner with single step junction. As a result, the antenna achieves a wide operational impedance BW ranging from 3.25 to 40 GHz...

The radiation pattern is dipole shape in the E-plane and almost omnidirectional in the...
In this paper a fast numerical algorithm to solve an integral equation model for wave propagation along a perfectly conducting two-dimensional terrain is suggested. It is applied to different actual terrain profiles and the results indicate very good agreement with published work. In addition, the proposed algorithm has achieved considerable saving in processing time. The formulation is extended to...
In this paper, a compact ultra-wideband (UWB) antenna with M-slot, three co-directional complementary split ring resonators (CSRRs) and ground staircase cut is proposed. The shape of the antenna achieves both the impedance matching of UWB and four rejection bands. The fabricated antenna is compact enough to be integrated into the UWB system. Measured results show the validity of the proposed design.
