| This paper proposes a two way L and S band Gysel power divider/combiner that uses line to ground resistors. Step by step methods to obtain a wide isolation and transmission bandwidth are presented. A design that uses five resistors is selected and optimized based on Quasi Newton method. Then the Defected Microstrip Structure (DMS) and Defected Ground Structure (DGS) is used to obtain better transmission and isolation in wider bandwidth. By resizing the structure to meet impedance matching, the two-way L and S band power divider is achieved. Also the optimization of the design is checked using circuit configuration. Finally, the theoretical results are validated by comparison with simulations of structure and experimental results. The simulations are found to be in good agreement with measurement results in the range of 0.7 to 4.3 GHz. | ||
