Higher performance, lower cost, and compact size antennas are important in today's
wireless communication system where everything is connected. Many approaches are …

In this paper compact Ultra Wideband (UWB) Vivaldi Tapered Slot Antenna (VTSA) is
designed simply by changing its Microstrip to Slot line (M/S) transition. To explain the effect …

The progressions in the field of wireless technology can be highly attributed to the
development of antennas, which can access high data rates, provide significant gain and …

Ultra Wideband radar systems have emerged as a good alternative for non-invasive and
harmless breast cancer detection. In this paper, bistatic and monostatic radar systems are …

This paper studies the feasibility of Microwave Imaging (MWI) for detection of fractures in
superficial bones like the tibia, using a simple and practical setup. First-responders could …

A new theory called Vivaldi nonuniform slot profile antenna (VNSPA) is developed based on
the nonuniform transmission lines (NTLs) theory and applied to reduce the size of the …

In this paper, we are interested in the design of a new Ultra-Wideband (UWB) directional
Vivaldi antenna with narrow beam, in the frequency range of 1.17 to 4.75 GHz. The …

This research proposes a through-wall S-band ultra-wideband (UWB) switched-antenna-
array radar scheme for detection of stationary human subjects from respiration. The …

The development of radar technology has an important role in several fields such as
aviation, civil engineering, geology, and medicine. One of the essential components of the …

In this paper, an ultra-wideband (UWB) antenna with highly directional property is
developed for microwave breast imaging applications. Two different patch antennas are …
