A portable breast cancer imaging system with cross-shaped dome antenna array

Imaging of a breast cancer phantom was demonstrated by use of radar-based ultra-wide-band (UWB) complementary metal oxide semiconductor integrated circuits (CMOS) with 16 cross-shaped dome array antennas on a hemispherical breast phantom. The dome antenna array was rotated and the combinations of transmitter and receiver antennas were selected by two CMOS switching matrices. A breast cancer phantom target in a silicone-based breast phantom was successfully detected by confocal imaging.
