  • Antenna Designs for Microwave Tissue Ablation

    Semi rigid coaxial cables have been widely used as feeding transmission lines within MW ablation applicators. The differences in the length of these two legs leads to an unbalanced dipole antenna. The difference in construction of the dipole and slot is that, in the dipole, the distal end is a solid metallic cylinder, whereas, in the slot
