Abstract
Bi-directional couplers for very overmoded tubular HE11 waveguides (consisting of arrays of coupling holes in mitre bends) as well as for Gaussian beam waveguides (consisting of phase gratings with small amplitude on mirror surfaces) have been designed, fabricated and tested at 70 and 140 GHz. High directivity and good mode selectivity have been obtained.
