Conclusions
The results discussed here can be useful for working with either large or small energy value millimeter and sub-millimeter wave ranges. For the former, the problem of optimal feeder choice is still unsolved. Such feeder should have large breakdown strength, small per unit attenuation, good electromagnetic hermiticity and mechanical durability. For the latter, the most important parameters are good commercial manufacturability, ability to ensure required values of electromagnetic coupling with various active elements, low cost, small weight and dimensions.
The prospects for new line utilization with millimeter waves are caused by essentially smaller, even in comparison with Н-guide, per unit length attenuations and better manufacturability along with the ability to "achieve coupling" in perpendicular directions ; the last property seems to be useful for:
* producing traveling-wave antenna with the complex form of polar patterns;
* for simultaneous realization of planar bonds and inter-planar coupling in three-dimensional integrated circuits.
