A novel, low-profile, directional UWB antenna for WBAN

Abstract

This paper presents a novel antenna design for ultra wide-band body area network applications. The design is composed of two Vivaldi shapes placed opposite to each other on the same substrate, which achieves constant impedance matching over a wide band and uniform radiation pattern. To reduce the backward radiation, two types of reflector were used: flat and curved. Results show that using a curved reflector enhances the radiation pattern on most of the UWB with less effect on the antenna impedance compared to the flat reflector.

A Low-Profile and Wideband Unidirectional Antenna Using Bandwidth Enhanced Resonance-Based Reflector for Fifth Generation (5G) Systems Applications

“…Ultra-wide band (UWB) directional antennas are characterized by high security, good efficiency, low transmission power and high data rates, thus, more attentions have been paid to UWB directional antennas, which are also desired with the characteristics of compactness and low-profile. Such an antenna has a significant role in many applications, such as point to point communication, military services, wireless body area networks (WBAN) and microwave imaging [1]- [5]. Moreover, the 5G systems are expected to be The associate editor coordinating the review of this manuscript and approving it for publication was Chan Hwang See.…”
