In this article, we propose a general design procedure to develop unequal split Bagley power dividers (BPDs). Based on the mathematical approach carried out in the insight of simple circuit and transmission line theories, exact design equations for 3-way and 5-way BPDs are derived. Utilising the developed equations leads to power dividers with the ability of offering different output power ratios through a suitable choice of the characteristic impedances of the interconnecting transmission lines. For verification purposes, a 1:2:1 3-way, 1:2:1:2:1 5-way and 1:3:1:3:1 5-way BPDs are designed and fabricated. The experimental and full-wave simulation results prove the validity of the designed unequal split BPDs.

This paper presents a design methodology for a dualfrequency unequal-split Bagley power divider (BPD). This is accomplished by replacing each quarter-wavelength transmission line by T-shaped transmission lines network. Simulation results obtained using the full-wave IE3D simulator prove the validity of the design procedure.I.
