- Materials Science
- IEEE Antennas and Wireless Propagation Letters
- 2017
We present a technique for minimizing the impact of coaxial baluns on the invasiveness of coax-fed microwave ablation (MWA) antennas. The technique uses an air-filled coax section at the end of a… Expand
A Minimally Invasive Coax-Fed Microwave Ablation Antenna With a Tapered Balun

- Materials Science
- IEEE Transactions on Antennas and Propagation
- 21 September 2017
We present a minimally invasive coax-fed dipole antenna with a tapered slot balun for microwave ablation (MWA) applications. The balun is created by gradually tapering the outer conductor of the… Expand
A Decoupling and Matching Network Design for Single- and Dual-Band Two-Element Antenna Arrays
This article presents a new decoupling and matching network (DMN) design for symmetric, single- and dual-band two-element antenna arrays. The DMNs use parallel-line-based coupling elements. The… Expand
