It is necessary to design antennas by considering human body in applications such as ultra-wideband (UWB) radar antennas for breast cancer diagnostic, body area network (BAN) and so on. The electromagnetic modeling of human body for design of those antennas has been investigated by the authors. A wideband pentagonal patch antenna using FR-4 substrate is proposed in the paper. The reflection coefficient is below -8 dB within UWB frequency range (3–10 GHz). It was confirmed by simulation that the variation of radiated electric field distribution against frequencies is small. Measured and calculated frequency characteristic of S-parameters matched well with each other for both single and 4 × 4 array antenna. It was also confirmed that the change of group delay is not large in UWB band.
