Abstract
A waveguide-to-microstrip transition (30) for converting and directing electromagnetic wave signals to an electronic signal processing component (53). A waveguide (32) directs the signals to a waveguide input and is received by a probe (36). A bent microstrip line (40A) which is connected to the probe (36) directs the received signals from the probe (36) to the electronic signal processing component (53). An output port (43) provides a connection between the bent microstrip line (40A) and the electronic signal processing component (53). The output port (43) is not inline with respect to the probe (36), but the microstrip line (40A) includes a bend so as to direct the received signals from the probe (36) to the output port (43).

A waveguide-to-microstrip transition for converting and directing electromagnetic wave signals to a signal processing component, comprising:
- a waveguide for directing said electromagnetic wave signals to a waveguide input;
- a substrate positioned on the waveguide and including an iris;
- a probe formed on the substrate for receiving said directed electromagnetic wave signal, said probe including a widened shorting stub portion and an elongated portion, said shorting stub portion being connected at one end of the elongated portion, said shorting stub portion being mounted on the substrate and said elongated portion extending across the iris;
- a bent microstrip line connected to said probe for directing said received electromagnetic wave signals from said probe to said electronic signal processing component, and
- a first stub and second stub being disposed on a substrate;
- whereby said first and second stubs have been short-circuited for substantially matching an impedance of said probe and an impedance of said bent microstrip line,
- an output port for providing a connection between said bent microstrip line and said electronic signal processing component, said output port not being inline with respect to the probe,
- said probe transitioning into said bent microstrip line along a first axis, said output port having a second axis which is at an angle other than 180 degrees from said first axis, said bent microstrip line including a bend so as to direct said received signals along the first axis of said probe to the second axis of said output port.
A waveguid-to-microstrip transition for converting and directing electromagnetic wave signals to an electronic signal processing component, comprising:
- a waveguide for directing said electromagnetic wave signals to a waveguide input;
- a substrate positioned on the waveguide and including an iris;
- a probe formed on the substrate for receiving said directed electromagnetic wave signals, said probe including a widened shortinq stub portion and an elongated portion, said shorting stub portion being connected at one end of the elongated portion, said shorting stub portion being mounted on the substrate and said elongated portion extending across the iris;
- a bent microstrip line connected to an end of the elongated portion of said probe opposite the shorting stub for directing said received electromagnefic wave signals from said probe to said electronic signal processing component, and
- an output port for providing a connection between said bent microstrip line and said electronic signal processing component, said output port being offset with respect to the probe,
- said bent microstrip line including a bend so as to direct said received electromagnetic wave signals from said probe to said output port, wherein said probe transitions into said bent microstrip line along a first axis, said output port having a second axis which is at an angle other than 180 degrees from said first axis, said bent microstrip line directing said received signals along the first axis of said probe to the second axis of said output port.
