Abstract:
A waveguide structure for coupling electromagnetic radiation to a coaxial connection, said coaxial connection including an inner conductor and an outer conductor, said structure comprising:a waveguide receiving the electromagnetic radiation, said waveguide including at least one surface being formed of a conductive metal and defining a ground plate, said outer conductor of said coaxial connection being connected to the conductive ground plate; anda probe positioned within the waveguide, said probe including a capacitive portion and an elongated conductive member, said capacitive portion defining a capacitance with the ground plate, said inner conductor of the coaxial connection being electrically connected to the probe so that the elongated conductive member extends in a direction substantially perpendicular to the inner conductor and transverse to the propagation direction of the electromagnetic radiation so that the electromagnetic radiation induces a current in the conductive member that is transferred to the inner conductor and the capacitive portion provides a shunt capacitance that resonates out the inductance created by the conductive member.
