Abstract :
In Wireless Body Area Network (WBAN) which is the network around a human body, Ultra Wide Band (UWB) communication is one of the candidates for a realizing a high transmission speed. However, the antenna characteristics can be degraded due to influence of the human body. Also, broadband antennas which cover the bandwidth of UWB are too large for WBAN´s antennas in general. In this paper, an antenna with a slot of a bow-tie shape focused and downsizing technique discussed. In comparison with the basic shape, it downsized by approximately 10% in the y-direction, 68% in the z-direction. And, average Front to Back ratio of 1.95dB is obtained in band from 4.7 to 10.6GHz.
