摘要

A transmission line model for the TFTR ICRF antenna is presented. The antenna is considered as being composed of mutually coupled transmission lines. Expressions for the input impedance of such a structure are given. Details of the considerations in setting up the antenna feed structure are presented. The requirement of dual feed drive coupled with the desire for phase and amplitude control place restrictions on the operating circuit.
