RF/microwave waveguide

A waveguide is a transmission medium for use in transferring radio frequency signals from a first location to a second, different location. Waveguides may be used for communicating signals at all frequencies of the electromagnetic spectrum such as at radio frequencies and radar frequencies in addition to optical frequencies. A waveguide is generally configured such that current and voltage distributions can be represented by one or more traveling waves, usually in the same direction. A waveguide may be a parallel plate type waveguide, or may be any rectangular or circular "pipe" that confines and guides electromagnetic waves between two locations. The waveguide may be coated with a highly reflective coating that causes the signal to be totally reflected from one side of the guide to the other. Signals are coupled into and out of the waveguide using transitions known as waveguide feeds. Waveguide feeds generally include one or more waveguide probes for launching energy into and sensing energy from the waveguide and some means for coupling electromagnetic energy to/from an external coaxial cable. A dielectric waveguide comprises a dielectric strip provided between two conductive planes, which are substantially parallel, so that electromagnetic waves are transmitted along the dielectric strip. One dielectric waveguide, a non radiative dielectric waveguide (NRD guide) is developed as a transmission waveguide exhibiting less transmission loss.
