Analysis of a Longitudinal Rectangular Waveguide Power Divider/Combiner Using Multiple Cavity Modeling Technique

A method of moment based analysis of the feed network of a waveguide fed two dimensional array antennas has been presented using Multi Cavity Modeling Technique (MCMT). The proposed power divider/combiner is unlikely to the structure of the family of Tees. The output ports are in the same planes as the input which is an advantage for phased array applications. The proposed longitudinal power divider/combiner has good agreement with the theory; CST microwave studio simulated and measured data. In the input of the waveguide at 10 GHz frequency band, it behaves as an H-Plane tee, over 2 GHz.
