Analysis of a disk-on-rod surface wave element inside a corrugated horn using the mode-matching technique

摘要: A disk-on-rod inside a corrugated horn is one of the configurations for dual-frequency or wide-band operation. mode-matching analysis method described. represented as series coaxial waveguide sections and circular connected to each other. Three kinds junctions need be considered: coaxial-to-coaxial, coaxial-to-circular, circular-to-circular. computer program was developed calculate scattering matrix radiation pattern horn. The software verified by experiment, good agreement between calculation measurement obtained. design gives an option Deep Space Network operation system, which currently two-horn/one-dichroic plate system.
