ABSTRACT:
A transducer adapted to couple radio frequency (R.F.) energy from a section of waveguide to a section of stripline is shown to comprise a section of stripline supporting a series of probes projecting inside the waveguide with a shaped length of a dielectric material disposed around the probes within the waveguide to match the velocity of propagation of the R.F. energy in the waveguide to the velocity of propagation in the stripline, thereby achieving tight coupling and improved directivity.
