We report on the design of a 45° incidence diplexer to be used in a millimeter‐wave radiometer. This equipment will be flown on a low‐orbiting satellite and should analyze the natural emissions of the Earth and the atmosphere in the bands around 90, 157, and 183 GHz. The diplexer has been realized with two grids of tripoles arranged in an equilateral triangular lattice and printed on both sides of a quartz slab. Experimental data are presented that are in good agreement with the theoretical predictions. © 1993 John Wiley & sons, Inc.
