NEW CONCEPTS FOR RF TRANSMISSION LINES
Abstract
A description is given of 4 new types of RF transmission lines for satisfactory use in the frequency band of 1 to 10 gc, with regard to bandwidth; low-loss, flexibility, and small size and weight. Four new RF transmission lines are recommended, based on 6 advanced concepts. The RF transmission lines are: (1) special coaxial cable for 1 - 3 gc use, (2) flat shielded Xguide for 3 - 7 gc use, (3) higher mode suppressed shielded X-guide for 7 - 10 gc use, and (4) balloon type O-guide (gas-filled thin dielectric pipe) for long distance communication use. The advanced concepts are: (1) the thin dielectric membrane surface wave transmission concept, (2) the double-layer thin dielectric membrane surface wave transmission concept, (3) the shielded dielectric waveguide concept, (4) higher mode suppression by using an anisotropic conductor, (5) the multi-layer stranded conductor concept, and (6) the transposed multi-layer conductor concept. The 4 lines and the 6 concepts are theorized in detail. Some experiments with the X-guide are given in order to verify the theoretical analysis. (Author)
