fn this paper we present a loiv-profile directional UWB antenna with improved radiation efficiency vhen operating in close vicinity to a biological tissuie. This antenna is intendedfor the use in UWB Wireless Body Area Aet cork (WBAAT) applications, betwveen 3 and 6 GAz. A novel design is based on a UWB slot antenna structure w4th an added radiato;rleflector element in order to achieve directional radiation pattern. We compaire resllts of our novel design, to those ofthe omni-directional UWB

Measurement and similotion resilts show that the developed directional UWB slot antenna has the improved radiaction efficiency in the vicinity of human body. Moreover, proximity of the h iman body much less influences its transfer finctions (the most important antenna parameter in UWB radio), compared to the omni-directional UWB monopole antenna.
