Abstract :
Spatial resolution of 4×4 planar ultra-wideband (UWB) antenna array was investigated for a confocal imaging system using Gaussian monocycle pulses. Two separate breast tumor phantoms having 5×5×5 mm3 embedded at the depth of 22 mm with the separation distance of 8 mm were resolved by use of 4×4 array antennas with 6 mm spacing due to the fact that the frequency characteristics of the antenna was improved in the frequency range from 6 to 10 GHz.
