Our analysis is for an ideal coupler, one which has no losses and the even- and odd-mode phase velocities are equal, so θ = θ = θ. We first e o 37 Coupled Transmission Lines and Modal Analysis consider the conditions for an input match. 2. 4), respectively. 12) = Z , Z = Z , as desired. 13) is the condition for matched ports. To find an expression for the coupling, in terms of voltage, we need to find V / V . 7). 20) and, finally, we can use that process to show that the voltage at port 3 is zero.

2 In the absence of radiation, however, its losses are fairly low, as its characteristic impedance is high (usually several hundred ohms) so the currents are relatively low, for a given power level. Its dimensions are generally large compared to other practical transmission lines. Parallel-wire line is sometimes used to feed large, low-frequency dipole antennas. A 300-ohm “twin lead,” a parallel-wire line embedded in polyethylene dielectric, was commonly used for television antenna lead-in cables until the mid-1980s.
