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.
Claims12
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.
Apparatus for coupling electromagnetic signals to a waveguide having a wall including a transverse endwall portion and a sidewall portion extending longitudinally therefrom to define an internal space, the apparatus comprising;
- 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.
Method for coupling electromagnetic signals to a waveguide having a wall including a transverse endwall portion and a sidewall portion extending longitudinally therefrom to define an internal space, the method comprising the steps of;
- providing 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;
- 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;
- supporting, with said waveguide wall, a pair of transmission walls to extend longitudinally in said waveguide internal space;
- and
- transversely spacing said transmission walls from one another to accommodate said probe transmission portion therebetween.
