[Also in Division H3] A microwave detector arrangement (see Division H3), utilizes a crystal diode 4 which is secured to the upper end of a connecting pin 6 held in a cylindrical conductive shielding sleeve 8 by means of an insulating ring 7. Connecting spring 5 is connected to the sleeve 8, the terminals of the detector being sleeve 8 and pin 6. The assembly is located in a conductive stump 2 provided at one corner of waveguide 1; the pin 6 extends into a vertical bore 9 provided in the middle of the side wall 10, while sleeve 8 lies within a circular aperture in stump 2, leaving narrow gap 11 so as to form a high capacitance which is substantially a short-circuit for microwaves. The gap 11 preferably has a height equal to one-quarter wavelength at the operating frequency.
