Abstract:An important element of any waveguide-based dispositive is the termination or load. At relatively large wavelengths the idea is to make them as compact as possible and usually contained inside of the waveguide. However, as the working frequency increases, the involved dimensions make more difficult such approach. In this memo, we describe a relatively simple waveguide load which is appropriate when the waveguide dimensions are prohibitory small. The load described here is rather large compared with the waveguide making it relatively easy to realize at small dimensions. Moreover, from the results of a simulation it is shown that besides its simplicity it can have a reflectivity as low as -40 dB if the appropriate material is used.
