Ultra-Wideband (UWB) technology has been gaining increasing interest from the industry due to its recent application in communications. The technology itself has been well known for decades and its use was mostly reduced to radars in industrial applications. During the standardization process which is not over yet, two realizations were proposed – Impulse Radio (IR), which has been known for ye...

It is very common that when a broadcaster needs to install an FM transmitting antenna within a large metropolitan area he places it on the tallest structure or building available. When the rooftop is already occupied by a large number of other types of transmitting and receiving antennas, the panel dipole antenna should be chosen. This antenna is secured to the side walls of the upper floors wi...

In this paper, a design of compact coplanar waveguide fed UWB slot antenna is presented. The proposed antenna has simple structure consisting rectangular slot with uneven coplanar ground structures. The proposed antenna structure is investigated by using MoM based electromagnetic solver IE3D. The simulation and measured results show that the antenna offers performance for wideband system from 4...

Based on the effective medium theory for multilayers, we present the design of several all-angle, polarization-insensitive absorbers spanning the visible, near-IR and part of the mid-IR (from 400nm to 3500nm) using periodic, one-dimensional, metallo-dielectric structures. OCIS codes (310.4165) Multilayer design; (310.3915) Metallic, opaque, and absorbing coatings. Visible and IR absorbing mater...

Nonlinear silicon photonics has been an immense research subject in the past several years with promising prospects of delivering chip scale signal modulation, shaping and characterization tools. In particular, broadband parametric process has been considered for applications ranging from wideband light amplifiers to signal characterization and signal shaping tools. Although underlying nonlinea...

Ultra Wide Band (UWB) technology is a developing wireless technology which promises high data rate short distance communication. In this paper, propose an advanced method for generating UWB signal for many UWB related applications. Important area of application is Wireless Local Area Network (WLAN). The basic idea of the work is to develop pulses of nanosecond range for the UWB transmission and...
