Microwave Ablation at 10.0 GHz Achieves Comparable Ablation Zones to 1.9 GHz in Ex Vivo Bovine Liver
TLDR
We demonstrate the feasibility of using high-frequency microwaves for tissue ablation by comparing the performance of a 10 GHz microwave ablation system with that of a 1.9 GHz system. Expand

A Balun-Free Helical Antenna for Minimally Invasive Microwave Ablation
We present a balun-free coax-fed helical antenna for microwave ablation. The proposed antenna produces a localized specific absorption rate pattern at the desired frequency of operation without using… Expand

The Performance of Higher Frequency Microwave Ablation in the Presence of Perfusion
TLDR
Higher-frequency microwave ablation produces thermal lesions with volumes comparable to those achieved at lower frequencies, even in strongly perfused environments. Expand

Wideband Transmitarrays Based on Polarization- Rotating Miniaturized-Element Frequency Selective Surfaces
We present a new low-profile, wideband, transmitarray design based on polarization-rotating (PR), miniaturized-element, frequency-selective surfaces (MEFSSs). These MEFSS unit cells rotate the… Expand

A Wideband, Single-Layer Reflectarray Exploiting a Polarization Rotating Unit Cell
We present a new technique for designing wideband, single-layer reflectarray antennas. The proposed reflectarray exploits a wideband, polarization rotating unit cell that rotates the polarization of… Expand

Reduced-Diameter Designs of Coax-Fed Microwave Ablation Antennas Equipped With Baluns
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
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

High frequency microwave ablation for targeted minimally invasive cancer treatment
We demonstrate the feasibility of microwave ablation of tissue using much higher frequencies (e.g. 10 GHz) than those used in conventional MWA (e.g., <; 2.5 GHz). In this study we compare the… Expand

Design Method for Low-Profile, Harmonic-Suppressed Filter-Antennas Using Miniaturized-Element Frequency Selective Surfaces
A new technique for designing low-profile filter-antennas with wideband harmonic suppression capability is introduced. A filter-antenna element in a periodic infinite array consists of a radiating… Expand
