Abstract
This paper describes an unequal Bagley divider using uniform transmission lines with adjustment electrical lengths between output ports. To obtain an arbitrary dividing ratio of Bagley divider, we have only adjusted the electrical lengths of the transmission line between output ports. All the transmission lines have the same characteristic impedance value. This design method does not require an impedance transformer for port matching. For verification, we simulated and fabricated a 3-way, 1:2:1 and 5-way, 2:3:4:3:2 ratio Bagley divider with an operating frequency of 2 GHz. The experimental results are in agreement with the simulated results.
