Waveguide T-junction and directional couplers are widely used in microwave/millimeter wave systems, because its circuit is simply and easily to be designed and fabricated. In this paper, a ka-band E-plane rectangular waveguide power divider is proposed and optimized. The first level of the network is the T-junction, which can halve the power for the first time, and the second level are two 3dB directional...
In this paper, two classes of Ka-band Substrate Integrated Waveguide(SIW) power divider are presented and studied. The advantages of the SIW technique are its low profile, low-lost, mass-productive, ease of fabrication and fully integrated with planar circuits. All the modules are designed to be operated in a wide frequency range. The Y-junction shows a bandwidth of 29.4%.
