1. A waveguide-to-waveguide power combiner/divider, comprising:

a waveguide having a first opening at a first end of a first section of the waveguide in a first plane and n openings of n sections at n other ends of the waveguide, wherein n is a positive integer greater than or equal to three, wherein at least one of the n sections is bent in at least one plane different from the first plane of the first section, and wherein the first section and the n sections each have at least two sides that are broader than at least two other sides; and

n−1 walls within the waveguide configured to divide a height of the first section into n heights, wherein each of the n sections has a height equal to one of the n heights, and wherein the n−1 walls are located at a junction of the first section and the n sections and extend toward the first opening of the first section;

wherein a length of at least one of the n sections is extended for path length equalization; and

wherein the heights of the n heights vary to provide insertion loss equalization.
