Preliminary fabrication and characterization of low-leakage hybrid coaxial cable

Abstract

In this paper we present the fabrication and the initial characterization of a new type of coaxial cable having reduced leakage characteristics and the capability of transmitting optical signals, in additional to the RF signal, through the glass medium between the metallic conductors. The suggested decreased leakage and material loss is obtained by using different metallic shield geometry. The suggested model is composed of a central conductor surrounded by plurality of metallic wires circularly disposed.
