This paper presents analysis of non-asymmetry antenna configuration for microwave ablation at 2450 MHz using three-dimensional finite element analyses. Treatment of hepatic cancer often requires removal or destruction. Using coaxial-slot antenna is opened slot at one-side of antenna. We study the characteristics of Antenna design for microwave hepatic ablation using an axisymmetric electromagnetic model - PubMed Central … Axial and radial schematics of a coaxial-based double slot choked antenna designed for hepatic microwave ablation (MWA). All units are in mm. where c is the speed of light in free space (m/s), f is the operating frequency of the microwave generator (2.45 GHz), and ε r = 44.4 is the relative permittivity of bovine liver tissue at the operating Development and Analysis of Coaxial Slot Antenna in … 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 …
