Abstract : The patent describes a miniature waveguide attenuator which may be used in a dominant-mode waveguide to maintain a low VSWR over a 20% frequency band, comprising a short section of waveguide with an E- or an H-plane tee whose width is selected to set the cutoff frequency of the branch line of the tee at the design frequency. The branch line of the tee is terminated in a lossy material followed by a short circuit for absorbing energy propagating down the waveguide at frequencies higher than the design frequency in accordance with a controlled attenuation characteristic.
