Abstract Semi-insulating (SI) silicon carbide (SiC) was evaluated as a candidate material for dielectric substrate for patch antennas suitable for monolithic antenna integration on a SiC semiconductor chip.
Microwave Tumor Ablation - JVIR triaxial, choked, or slotted antennas. (38–44). Microwave antenna design is a bal- ance of power efficiency, tissue heating pattern, and antenna diameter with de ...
Microwave ablation (MWA) is a promising thermal therapy that uses heat to kill tumors. A large ablation zone with high circularity is desirable in clinical setting because most tumors are nearly spherical shapes. Single or multiple slot antennas are favored in MWA due to their good clinical outcomes, small dimensions and easy fabrication.
Antenna design for microwave hepatic ablation using an … Feb 27, 2006 · An axisymmetric finite element method (FEM) model was employed to demonstrate important techniques used in the design of antennas for hepatic microwave ablation (MWA). To effectively treat deep-seated hepatic tumors, these antennas should produce a highly localized specific absorption rate (SAR) pattern and be efficient radiators at approved generator frequencies. Microwave Ablation Antenna with the ablation pattern being a … Jul 22, 2016 · The Microwave Ablation Antenna works at 2.45GHz and also has a good impedance matching. This kind of Microwave Ablation Antenna can solve the specific shape of the tumor and to realize a large ablation pattern, meanwhile our design has lesser damage to body (for the outer radius of the coaxial-slot antenna is less than 4mm). 3D FINITE ELEMENT ANALYSIS FOR NON- ASYMMETRY …
Finite element analysis for optimizing antenna
Erdem Topsakal - Academia.edu Abstract Semi-insulating (SI) silicon carbide (SiC) was evaluated as a candidate material for dielectric substrate for patch antennas suitable for monolithic antenna integration on a SiC semiconductor chip. Vol 3 No 1 (2014) | Advanced Electromagnetics
while the inside of the tip of a slot antenna is still the dielectric of the coaxial cable. Like all other antennas, a slot antenna is usually sealed in its catheter to be used in MWA procedure. For frequency at 2.45 GHz, a slot antenna works very similarly to a dipole antenna having very low power reflection of -16 dB as shown in Fig. 3. An analysis of heat transfer in liver tissue during microwave ablation using single and double slot antenna …
