Development of a Symmetric Waveguide T-Junction Power Divider with Equal-Phase Characteristic

An efficient method is proposed to design a versatile rectangular waveguide T-junction power divider without changing the length of either of the output branches for phase compensation. Instead, the phase balance is controlled by the widths of the output branches, which, in turn, help to achieve the same timeof-arrival of waves propagating to the two output ports. This method does not sacrifice the T-junction's symmetric characteristic physically. Numerical analysis has been utilized to design several T-junction power dividers operating in Ku-Band with different power ratios, and results are compared with the measured ones to verify the design feasibility.
