Radiation Physics from Two-Wire Transmission Lines
The radiation mechanisms from two-wire transmission lines in the gigahertz range were analysed through method of moment (MOM) and the developed analytical formula. Total radiation power (TRP) was used to evaluate the radiation from a straight two-wire transmission line and a two-wire transmission line with right-angle bends. The contribution of the wire segments connecting the source and load to the two-wire transmission line and the contribution of the right-angle bends to the TRP were analysed with travelling wave currents on the two wires. The increase of TRP from the bent wire is due to the change of the current locations, not caused by the reflections at the bends. With standing-wave currents on the wires, the radiation increases dramatically at half-wavelength resonances when there is significant increase of current magnitude at these resonances.
