Development of a Compact Wide-Slot Antenna for Early Stage Breast Cancer Detection Featuring Circular Array Full-View Geometry

Abstract EN

A novel planar type antenna printed on a high permittivity Rogers’ substrate is proposed for early stage microwave breast cancer detection.

The design is based on a p-shaped wide-slot structure with 5 0 Ω microstrip feeding circuit to eliminate losses of transmission.

The design parameters are optimized resulting in a good reflection coefficient at −10 dB from 4.5 to 10.9 GHz.

Imaging result using inhomogeneous breast phantom indicates that the proposed antenna is capable of detecting a 5 mm size cancerous tumor embedded inside the fibroglandular region with dielectric contrast between the target and the surrounding materials ranging from 1.7 : 1 to 3.6 : 1.
