Abstract :
This paper proposes a miniaturized Wilkinson power divider by folding the quarter-wavelength section of the conventional topology into the meander coupled line with inductive slit. It is not only physically small, but also provides better electrical performance than that of the conventional one. Additionally, we have investigated the performance of this divider using an EM simulator and obtained a design formula for an optimum structure. This divider has return loss of 30 dB, isolation of 55 dB at the center frequency of 1.5 GHz, and the fractional bandwidth of approximately 73% (S11<15 dB). Experimental results are in good agreement with simulation results
