A wideband bow-tie antenna has been designed using the finite-difference time-domain (FDTD) method. When positioned at the surface of a biological tissue half-space, the calculated reflections from the antenna ends are 106 dB below the exciting pulse. This facilitates detection of local weakly-scattering tissue structures
