Electromagnetic Field-to-Wire Coupling in the SHF/EHF Frequency Range

摘要

A feasibility study has been conducted to examine methods of treating field-to-wire coupling in the SHF/EHF frequency range. In this region, transmission line lenghts and wire separations become very large electrically, and field-to-wire coupling problems become intractable. Several types of transmission lines have been examined in the SHF/EHF range, including uniform and non-uniform transmission lines, coaxial transmission lines, and multi-conductor transmission lines. Current distributions are predominantly of the standing-wave or traveling-wave form. The higher order modes are not significant for those cases examined. Rounds may be obtained for induced currents in the field-to-wire problem by considering the transmission line as an antenna and using the equivalent circuit of the receiving antenna which has been extended to multiport receivers. A method has thus been outlined for treating transmission lines at SHF/EHF.
