N-Way Microstrip Power Divider/Combiner Design for Satellite Communications

The Wilkinson power divider is a well-known device used for splitting or combining signals. Composed of resistors and quarter wavelength transmission line sections, it is widely used in order to be fed to a phased antenna array system. In this system a signal is either fed through an equal split power divider featuring a specific number of output ports, or a series of equal split power dividers. The split signals are then fed through phase shifters and then to an array of transmitting antennas. In this thesis the focus is on the design, fabrication, and tests of the two-way and eight-way equal Wilkinson power dividers/combiners in phase at 19.2GHz and 29GHz with operation bandwidth ±1.5GHz. The three-way cascade Wilkinson power divider/combiner in phase has also been designed, fabricated and tested at 19.2GHz with operation bandwidth ±1.5GHz.
