Abstract
Abstract A structure (20) coupling a microwave signal to a waveguide (30) is provided. Transmission walls (26) are supported in the waveguide to only partially surround a probe (22) extending longitudinally from the waveguide wall. The probe preferably terminates at one end in a transmit/receive portion (36) directed into the waveguide internal space and at the other end in a launch portion extending through either the waveguide endwall (24) or sidewall (28). The structure is particularly suited for economical fabrication.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
123 words
A waveguide coupling structure, comprising: a waveguide comprising a wall including a transverse endwall portion and a sidewall portion extending longitudinally therefrom to define an internal space; an elongate probe having a transmit/receive portion at a first end, a launch portion at a second end, and a transmission portion connecting said transmit/receive and launch portions; means for mounting said probe on said wall with said transmission portion extending longitudinally in said internal space and said launch portion extending externally through said wall; and a partially open transmission member having first and second transmission walls supported by said waveguide wall and oriented longitudinally in said waveguide internal space, said transmission walls being transversely spaced from one another and accommodating said probe transmission portion therebetween.
Claim 2
Dependent Claim
