ABSTRACT: The present work designed and investigated a 3D basic model for breast
cancer detection at the ISM band. The model consists of two multi-slotted
rectangular patch antennas and a three-layer breast phantom containing two
tumors. A multi-slotted antenna was designed at 2.45 GHz using CST STUDIO SUITE 2018, where the simulated
results showed a return loss better than -35 dB and attended more than 77 MHz bandwidth. The diagnosis approach is based on
exploiting the electrical properties (frequency dependent) of breast tissues, i.e., mass density,
relative permittivity, and conductivity. Once the proposed slotted antenna
radiates electromagnetic signals toward the breast model (with and without
tumors), the radiation properties in terms of the scattering parameters (S11 and S21), the electrical field, the power flow, the current density,
and the power loss density were altered. As a result, the values of these
radiation parameters increased when tumors were implanted inside the breast
model, informing the presence of cancerous tissues. Moreover, the specific
absorption rate (SAR) was estimated as a function of input powers, where the
proposed antenna showed a set of low SAR values compared to the IEEE standard
of 1.6 W/kg,
validating its potential use for diagnosing purposes. The simulated results
indicated the prospective use of two slotted antennas (in the first instance)
to detect multiple tumors which could be a challenging task using a
single-element antenna, where the ultimate goal is to realize a compact antenna
array to detect multi-tumors.
