Investigation of wideband Wilkinson power divider using multi-section approach

This paper investigates the performance of two Wilkinson power dividers over a wide band frequencies range from 1 to 13 GHz. The first power divider is designed and developed using single section method while the second power divider is designed using double section method. The main purpose of this study is to determine how much bandwidth improvement can be achieved using double section compared to single section approach. Both designs are investigated using CST Microwave Studio simulation tool. The designs are fabricated on microstrip printed circuit board and measured using vector network analyzer. The simulated and experimental results of both developed dividers are compared and analyzed.
