Compact Conformal Multilayer Slot Antenna for Hyperthermia
A compact, conformal applicator having good impedance matching over various loaded conditions with minimum leakage radiation is desirable for hyperthermia treatment of cancer. Hence, in this paper, a new compact conformal multilayer slot antenna with embedded water bolus terminated in muscle medium is presented for hyperthermia application. A simple $50 \Omega$ microstrip line with fork-shaped tuning stub is used to excite the proposed conformal antenna. The antenna input reflection coefficient and hyperthermia assurance parameters viz. effective field size, depth at $\Delta\mathrm{T} /2$ and heating area in the tissue medium are evaluated for different antenna curvature at 2.45 GHz (curvature of the applicator is identical to the bio-model). The simulation results for the proposed antenna show a reduced tissue surface heating and back field irradiation.
