Dipole antenna design as hyperthermia applicator using CST microwave studio

Compact Antenna Simulation with CST MICROWAVE STUDIO®

This article demonstrates the simulation of an electrically large antenna. The design and numerical results are courtesy and permission of Chelton Antennas, France. The antenna operates at 8 GHz and was simulated using the CST MICROWAVE STUDIO® (CST MWS) Transient Solver which is, as a result of its efficient memory scaling, ideal for such electrically large structures. In this case, the antenn...

Study The Various Feeding Techniques of Microstrip Antenna Using Design and Simulation Using CST Microwave Studio

Microstrip patch antennas can be fed by a variety of methods. These methods can be classified into two categoriescontacting and non-contacting. In the contacting method, the RF power is fed directly to the radiating patch using a connecting element such as a microstrip line. In the non-contacting scheme, electromagnetic field coupling is done to transfer power between the microstrip line and th...

Optimization of Inductively Coupled Coils using CST Microwave Studio

A head and neck hyperthermia applicator: theoretical antenna array design.

PURPOSE Investigation into the feasibility of a circular array of dipole antennas to deposit RF-energy centrally in the neck as a function of: (1) patient positioning, (2) antenna ring radius, (3) number of antenna rings, (4) number of antennas per ring and (5) distance between antenna rings. MATERIALS AND METHODS Power absorption (PA) distributions in realistic, head and neck, anatomy models...

Coaxial Slot Antenna Design for Microwave Hyperthermia using Finite- Difference Time-Domain and Finite Element Method

Hyperthermia also called thermal therapy or thermotherapy is a type of cancer treatment in which body tissue is exposed to high temperatures. Research has shown that high temperatures can damage and kill cancer cells, usually with minimal injury to normal tissues. Otherwise, ablation or high temperature hyperthermia, including lasers and the use of radiofrequency, microwaves, and high-intensity...
