Key result
A 915-MHz cap-choke antenna for microwave ablation shows excellent agreement between modeling and phantom measurements.
Why the study?
A 915-MHz antenna design is needed that produces specific absorption rate distributions with preferential power deposition for microwave thermal ablation therapy.
The designed 915-MHz cap-choke antenna demonstrates favorable heating profiles and minimal reflected microwave current, making it suitable for intracavitary microwave thermal ablation therapy.

Does not support clinical use; leaves open in vivo validation of the 915-MHz antenna for ablation.
Pisa et al. (2001) studied microwave thermal ablation therapy. 915-MHz cap-choke antenna was evaluated on specific absorption rate distributions and heating. A 915-MHz cap-choke antenna designed for microwave thermal ablation demonstrated excellent agreement between numerical modeling and experimental measurements in tissue equivalent phantom materials.
