Abstract

REDUCED-HEIGHT WAVEGUIDE-TO-MICROSTRIP TRANSITION
Abstract The present invention relates to a transition wherein a microstrip line (10), formed on one major surface of a substrate (11), is capacitively coupled to a reduced-height waveguide (15), comprising a predetermined width-to-height ratio, by means of a T-bar conductive pattern (12) formed on a substrate at the end of the microstrip line. Such T-bar transitions can also be connected on opposite ends of the microstrip line to provide connections between two waveguide sections. (FIG. 1)
