Besides providing multiple services for emerging applications, ultra-wideband antennas play an important role in cancer detection in human tissues by acting as biosensors. The proposed biosensor consists of a slotted ground patch antenna (SGPA) backed by a metasurface (MS). The reported antenna’s expanded meandering line topology reduces size to \({0.08\lambda }^{2}\) . The etching of ground slots induces a multiple resonance which encompasses together to form UWB ranging from 3.92 GHz to 13.1 GHz. The metasurface is made up of 3 × 5 arrangement of an epsilon negative (ENG) metamaterials. The ENG property of the presented metamaterial redirects the signal in the forward direction and thus enhances the gain to 7.2 dBi. The estimated group delay and fidelity factor (FF) for the proposed biosensing system are under 1 ns and 85.8%, respectively, which guarantees minimal distortion. The measurements are done with breast cancer detection system which consists of dual antenna with MS acting as a biosensor, breast model with tumor and imaging system to perform microwave imaging (MWI) for detecting cancerous tumors.
