Abstract :
A novel ultra-wideband (UWB) antenna oriented for imaging cancerous cells in human breast is proposed. Fed by 50 Ω microstrip line, the proposed design features a p-shaped wide-slot and printed on PCB substrate of size of 16 mm × 16 mm. This design is optimized resulting in an improved array ability and wideband characteristics. The image reconstruction is performed using the enhanced version of the delay-and-sum algorithm, from which the cross-sectional image depicting the permittivity distributions in heterogeneous breast is produced.
