Optimization of microwave T junction power-divider circuits

In our earlier paper we had developed microstrip T junction models, from a qualitative design aspect, to act as equal and unequal power-dividers. In this paper, we have applied optimization techniques to design power-divider circuits which give pre-specified transmission characteristics. These circuits include the asymmetrical tee, the 1-step tee, the 2-step tee and the linearly tapered tee junction circuits, The results give the optimized dimensions of the latter four circuits for different power-divider ratios.
