An edge-guide mode microstrip isolator with transverse slot discontinuity

A novel configuration edge-guide mode isolator is described. The device utilizes a transverse slot, located at one edge of the upper conductor, to effect the isolation function. Results are reported on a series of experiments which confirm operation of the device. Considerations for optimizing performance are detailed, and supporting experimental data are included. A modified distributed lossy-termination Hines-type isolator is also considered.<>
